Is there an IDE which specifically supports Objective-C and has linked with Cocoa Touch (optionally Cocoa) build tools for easy writing, building and running of programs?
I am looking to switch from XCode because XCode is buggy and crashes when I load files which has thousands of lines of code. Also the beautifier isn't good. It's not that performant.
It doesn't need to come with Interface Builder. I just need to write Objective-C in the IDE. More like Aptana if you have been a web developer.
Jetbrains have AppCode http://www.jetbrains.com/objc/. it is an IntelliJ based alternative for Xcode but depends on an installed Xcode for IB and CoreData.
Only for writing Obj-C Code, you can use any text editor.
You can not draw any UI like IB, but you can code to construct any of the UI elements.
However I would suggest to use BBEdit.
Or if you wish you can go for any C / C++ / Java IDE. But it wont compile for compiling you need to to switch back to XCode.
Or you can compile through terminal by giving the following command.
xcodebuild -project "delta.xcodeproj" -target "delta" -configuration Release OBJROOT="/Users/anoop/desktop/delta" SYMROOT="/Users/anoop/desktop/delta"
I feel your pain but even if you find an IDE other than XCode you will find yourself coming back to XCode to do something anyway such as the Interface Builder, etc.
Also, unfortunately, AppCode also not perfect. There are scenarios it doesn't cover yet that might hinder you from migrating or cause you to do heavy hacks to get it to work.
However, I have a project with hundreds of files including source files and it works fine for me. I do admit that it crashes from time to time but there is nothing you can do about it. Maybe try refactoring your project to reduce the size of your source files. I did find having large text files can cause it to go bonkers. But it is a good practice anyway to have small class files. Maybe what you are describing is a code smell of bloated classes?
I'm not meaning to offend you or anything. It's just another perspective for you to look at. Use it or don't use it.

I have a project from 2 years ago that I'd like to bring back into action in xcode.
Is there a simple way to do away with the old style memory management I have in there with retain/releases and use the new .. ARM?
And this is a 32bit app using the QTKit and QuickTime frameworks - can this become a 64bit app that I can put on the App Store one day if it works well?
Also I realise that my app is one enormous .h and .m file - i'd like to break it into smaller files to make it easier to read and find what i am doing - any tips on how to do that?
Thanks guys!

Use the Xcode menu item Edit->Refactor->Convert To Objective-C ARC which can automatically convert everything to ARC.
You can also use Edit->Refactor->Convert to Modern Objective-C syntax to update the code to use the new array/dictionary/number literal syntax.
For breaking out one file into many, Xcode's built-in refacting support is pretty terrible. You can try out Jetbrains Appcode which has much better support for this kind of thing.
This question pops up quite often here, even if just implicitly when users mistag their iOS questions. So, what’s the difference between Xcode, Objective-C and Cocoa?
Objective-C is a programming language. It could be said that it’s just a description of what valid Objective-C programs look like and what they mean. If you have a source code listing written in Objective-C, you need an interpreter or a compiler to put the listing to work. Languages like Objective-C are usually compiled, so most people use a compiler (like LLVM). Objective-C is almost exclusively used to develop for iOS and OS X, but there are other uses, too – as an example, some people write Objective-C for Linux.
You can use a text editor to write the sources and a compiler to turn them into an actual programs, but with modern technologies there’s much more to take care of, so that there is another program to make your job easier. These are called Integrated Development Environments, or IDEs. An IDE offers you a convenient way to edit the sources, compile them, debug the resulting programs, read the documentation, and many other things. Xcode is one such IDE. An important observation here is that Xcode does not compile your sources itself, it just calls the standalone compiler (LLVM). And Xcode is not the only IDE you can use to develop Objective-C apps – there’s AppCode, for example.
Writing iOS or OS X apps from scratch each time would be very time-consuming. That’s why Apple provides the developers with a good set of libraries. The libraries are simply a huge amount of source code written by Apple, and this source code takes care of most things that apps have in common. These libraries are called Cocoa.
Now, if you can’t figure out how to extend a class, you are most probably talking about Objective-C. It doesn’t have anything to do with Xcode or Cocoa, you could be very well writing some GNUstep code for Linux using Vim as an IDE and GCC as a compiler. On the other hand, if your Xcode build process fails because of some mysterious setting, or if you’re trying to build a static library in Xcode, that’s clearly an Xcode issue. And if you can’t figure out how to use some NSObject facility or the NSFileManager class, that’s Cocoa. (But it doesn’t have to be Xcode-related, as you could use AppCode or TextMate as your IDE!)
Originally available on my blog. Feel free to link to the blog post or this question when retagging or explaining the difference.
Xcode is the integrated development environment (IDE)—the application—that developers use to write software for iOS and/or OS X. It includes the editor, the build system (determining what to build to produce the desired target), and quite a few other things.
Objective-C is the main language that developers write such software in. They may write bits of it in pure C, use C++ or combine it with Objective-C (producing Objective-C++), or write some or all of the program in another language entirely, such as MacRuby, Java (with j2objc), or C# (with MonoTouch).
Xcode includes the Clang compiler, which turns code written in Objective-C, C, and a few other languages into executable code. Most error messages come from Clang, and Xcode relies heavily on it for search indexing, syntax highlighting, and name completion of Objective-C code.
Cocoa and Cocoa Touch are application frameworks. Each one is a suite of many individual frameworks (libraries stored in folders named blahblah.framework), such as:
Foundation (both): General object-oriented utilities, including NSString, NSURL, NSFileManager, etc.
Core Foundation (both): Mostly the same thing, but different, mainly in having a C-based API rather than Objective-C
Application Kit (Mac): Application and windowing framework
UIKit (iOS): Application and windowing framework
Core Graphics (both): Drawing
Core Animation (both): Sprite-management and animation framework
(and many, many more where they came from, especially on the Mac)
So:
You can use a framework besides Cocoa or Cocoa Touch, but you'll have to have some Cocoa/Cocoa Touch code, at some level, in order for your application to talk to the system, receive events, draw, etc. Frameworks that specifically target Mac and/or iOS will include the relevant wrappers for you, at varying levels of quality.
You can use a language besides Objective-C, but you'll have lots of syntactic awkwardness, as most of Cocoa and Cocoa Touch are designed for Objective-C's unique syntactic features (particularly selectors).
You can use an editor besides Xcode, and you can even use a build system besides Xcode (such as make), but Apple's App Stores expect apps built a particular way (especially with regard to code signing), so unless you're not targeting the App Stores, any other build system has to replicate what Xcode does or risk its users getting rejections.
A clear mistake is failing to differentiate Xcode from everything else. Xcode is the tool you are using to program in - to edit code, run code, etc. So if you are having trouble with the tool (e.g., the window doesn't show you your code properly, or you're having trouble drawing your interface, etc.), that's an Xcode problem.
If you don't understand why your code doesn't work, you're probably having an Objective-C problem or a Cocoa problem. But you won't necessarily know which.
It's an Objective-C problem if the root of your trouble is that you don't know how the language works (e.g. you don't know what the asterisk is for, or that declaration is not instantiation, or that messages to nil do not error out but don't do anything either).
It's a Cocoa problem if you don't grasp the delegate architecture or how a view controller works.
But my experience of the way people pose questions is that you may be ignorant of which of these you are ignorant of. I don't mean you personally, I mean all of us. This can make it difficult to pose the question properly because you don't know what exactly it is that you don't know — if you did, you'd know it and you probably wouldn't be having a problem (you'd be fixing the problem and on to the next thing).
Are there frameworks/generators for producing iOS code from any other language?
A dynamic language like JavaScript, ruby or Python are preferred. Googling for iOS code generators was largely fruitless.
The problem with systems like PhoneGap is that their output is a full-fledged application. What I need to produce is a library (.a & .h file eventually) that other Objective-C developers can reuse in their projects.
RubyMotion may or may not do what you want. I haven't seen much about the practicalities of it yet, but I'm thinking since it's statically compiled chances are good that it can produce libraries that can be simply linked into Objective-C projects. One might need another tool to produce the header files.
Of course, this is all speculation.
I think the best solution for what you're looking for is Titanium. It has its own sdk (in JavaScript), a complete IDE and allows you to have one codebase for all major platforms (iOS, Android included). What it's really awesome is the fact that it actually generates native code (a valid XCode project or a Java one for Android). It's also free and open source. Definetely worth a look.
I've never seen code generators, but there are a variety of "spoofs" as it were.

I've seen links to python libraries and I think java too.
When it comes down to it though, they're all work arounds, not direct development.
I think Xcode is a good IDE, but having used Eclipse for Java development in the past I am quite underwhelmed by XCode's code completion and error/warning feedback. (Most of the time, XCode seems to simply try to match the beginning of a text fragment to "words" in the same document, without even using type information to try to determine the appropriateness of a suggested completion.)
Does anyone have ideas or tricks to make XCode approach Eclipse's cleverness, or to realistically develop Cocoa apps with other IDE:s than XCode?
EDIT: Worth keeping an eye on this: code.google.com/p/objectiveclipse/
The good news is, Apple’s working on the problem. One of the goals of the clang compiler project is to create a reusable parser which can be used for better code completion and refactoring support. Indications are that this has borne fruit in the latest Snow Leopard seeds.
Quite simply: no.
You can do almost everything by hand using your favorite text editor but it's not at all recommended. Try designing interfaces without Interface Builder for example.
My advice would be to just stick with Xcode and learn its way of doing things. Yes, it will be different and sometimes might not be "better" in your Eclipsed eyes. Console yourself in the fact that Apple's managed to release some great products using Xcode.
My personal experience is that, each time I use Xcode, I find a new trick which I can add to my bag. Xcode is far more full-featured than what you might think at first (or second) glance.
I've long voiced my rants about what's wrong with Xcode (and what's not wrong with Xcode). But you really don't want to use another tool. And without breaking NDA: Xcode 3.2 with SnowLeopard: Hooray. (Compared to what we have; not compared to what we might want.)
That said, to your original question about code completion, I personally turn off auto-completion in favor of on-demand completion. I find it far more useful and less distracting. In the Code Sense panel, set "Automatically Suggest" to "Never" and make sure the other two options are selected ("Show arguments in pop-up list" and "Insert argument placeholders...") This will do completion in a pop-up box when you hit Escape, making it easy to scroll through looking for what you want. I find that I have to type a lot less this way, especially for methods that are not unique for many characters. 80% of the time, it's highlighting the right thing already.
I have certainly felt your pain — as an experienced Java developer and frequent Eclipse user, I've wished for the same features myself. Unfortunately, I'm not aware of anything that fits the bill. I don't think there was any satisfactory resolution to this SO question, either.
However, I think you'll be quite happy with the improvements to Xcode code completion coming in Snow Leopard — it's vastly smarter about filtering the list of possible completions. Also, there are new conveniences for coding, such as inserting a starting bracket when you forgot one, etc. To my knowledge, there is still no predictive compiling like Eclipse, though.
Is anyone aware of an IDE other than Eclipse that supports predictive compiling and warning/error reporting? Does Eclipse itself support the feature for languages other than Java, such as C++? I'm led to wonder whether the fact that Java is built with independent .java files rather than .h and .c/.cpp/.m files makes it simpler to predictively compile. Also, anything compiled with gcc requires a little more care and attention than the comparatively simpler javac command. Any thoughts?
Check out JetBrains' new IDE called "App Code". It's still in the Early Access Program, but even with the Early Access bugs it is hands-down better than xcode 4.

Xcode does have some context awareness, when you are sending a message to an object it will generally have the "ESC" list pull up meaningful arguments.
One thing I strongly recommend is looking into text macros. These are not really type aware, but they can save a ton of typing - for instance, after #implementation type "init" and then hit control-. (period) to activate the text macro. It will fill out a whole init method for you. You can create your own, or override the existing macros.
I'm a complete Xcode/Objective-C/Cocoa newbie but I'm learning fast and really starting to enjoy getting to grips with a new language, platform and paradigm.
One thing is though, having been using Visual Studio with R# for so long I've kind of been spoiled with the coding tools such as refactorings and completion etc and as far as I can tell Xcode has some fairly limited built in support for this stuff.
On that note, does anyone know if any add-ins or whatever are available for the Xcode environment which add coding helpers such as automatically generating implementation skeletons from a class interface definition etc?
I suspect there aren't but I suppose it can't help to ask.
You sound as if you're looking for three major things: code templates, refactoring tools, and auto-completion.
The good news is that Xcode 3 and later come with superb auto-completion and template support. By default, you have to explicitly request completion by hitting the escape key. (This actually works in all NSTextViews; try it!) If you want to have the completions appear automatically, you can go to Preferences -> Code Sense and set the pop-up to appear automatically after a few seconds. You should find good completions for C and Objective-C code, and pretty good completions for C++.
Xcode also has a solid template/skeleton system that you can use. You can see what templates are available by default by going to Edit -> Insert Text Macro. Of course, you don't want to insert text macros with the mouse; that defeats the point. Instead, you have two options:
Back in Preferences,go to Key Bindings, and then, under Menu Key Bindings, assign a specific shortcut to macros you use often. I personally don't bother doing this, but I know plenty of great Mac devs who do
Use the CompletionPrefix. By default, nearly all of the templates have a special prefix that, if you type and then hit the escape key, will result in the template being inserted. You can use Control-/ to move between the completion fields.
You can see a full list of Xcode's default macros and their associated CompletionPrefixes at Crooked Spin.
You can also add your own macros, or modify the defaults. To do so, edit the file /Developer/Library/Xcode/Specifications/{C,HTML}.xctxtmacro. The syntax should be self-explanatory, if not terribly friendly.
Unfortunately, if you're addicted to R#, you will be disappointed by your refactoring options. Basic refactoring is provided within Xcode through the context menu or by hitting Shift-Apple-J. From there, you can extract and rename methods, promote and demote them through the class hierarchy, and a few other common operations. Unfortunately, neither Xcode nor any third-party utilities offer anything approaching Resharper, so on that front, you're currently out of luck. Thankfully, Apple has already demonstrated versions of Xcode in the works that have vastly improved refactoring capabilities, so hopefully you won't have to wait too long before the situation starts to improve.
I'm excited to say that JetBrains have decided to make a decent IDE for Objective-C coders.
It's called AppCode and it's based on their other tools like RubyMine and Resharper. It's not native Cocoa, but has loads of raw refactoring power.

I've started using it for my main Objective C project and I'm already in love. It's still in it's infancy, but for code editing and refactoring it already blows Xcode away.
Update
It's now at a totally usable speed. I've switched over to it full time and it still blows my mind how amazing refactoring and coding is compared with Xcode. It just handles so much for you - auto importing, almost infinite customisation. It makes Xcode look like a toy.
Xcode has refactoring for C and Objective-C built in. Just select what you'd like to refactor, choose "Refactor..." from either the menu bar or the contextual menu, and you'll get a window including the available refactorings and a preview area.
Xcode doesn't currently have a public plug-in API; if there are specific types of plug-ins you'd like Apple to enable, file enhancement requests in the Bug Reporter. That way Apple can count and track such requests.
However, there are third-party tools like Accessorizer and mogenerator (the latest release is mogenerator 1.10) that you can use to make various development tasks faster. Accessorizer helps you create accessor methods for your classes, while mogenerator does more advanced code generation for Core Data managed object classes that are modeled using Xcode's modeling tools.
Just so people know, Accessorizer does more than just generate accessors (both 1.0 and properties for 2.0) it also generates Core Data code for persisting non-standard attributes, your NSSet accessors for custom to-many relationships.
In fact, Accessorizer will help provide you with the init, keypath, keyed-archiving, indexed accessors, accessors for unordered collections such as NSSet, copyWithZone, KVO, key-validation, singleton overrides, dealloc, setNilForKey, non-standard attribute persistence (Core Data), locking, headerdoc, convert method to selector, NSUndoManager methods and more.
I found some xtmacro files in Xcode.app package:
/Developer/Applications/Xcode.app/Contents/PlugIns/TextMacros.xctxtmacro/Contents/Resources
Installed Xcode ver. 3.2.5.
