We have a Mac application we wrote about 3 years ago. We've been maintaining it through all versions of OS X since Leopard (10.5). It's a 32 bit universal binary and is part of a suite of packages, all compiled and built the same way.
All apps are working under Mavericks except one, and only one part of it is broken. In this "broken" app we have a menu option that allows the user to open up a simple logging window. All this thing is is an NSPanel with a text view in it. When we open it, the spinning beach ball comes up and observing the console, it identifies this program as "hung."
This thing has been working for years. It works on both PPC and Intel from Leopard up through Mountain Lion. I thought for sure there was deprecated code in it somewhere, but I went through it and couldn't find any. There's really not much to it anyway. All it does is open up and spit out text. I then traced through the code and found out the nib wasn't loading.
I have Xcode 3.2.5 installed on this system (it's been upgraded since Snow Leopard) without iPhone support and it seems to work. In any case, I thought I'd take a look at the actual contents and window layout to see if maybe I had some unsupported or dated support, and when I double click on the xib file from Xcode, when Interface Builder opens up, it locks up too. We have I think 5 xib files in this application, so I double clicked on all of them and they all open up properly in Interface Builder. The only one locking up is this one. As a test, I opened the xib up in Xcode 4 and it opened up properly.
We can't really move to Xcode 4 because we have a fair number of clients (about 30%) still using Leopard and Snow Leopard. We typically build in either Lion or Snow Leopard. but haven't had any problems compiling and building under Mountain Lion. This app, and all the other we have will compile and build using Xcode 3.2.5 on the Mavericks system. Everything seems to work except this one xib file.
Has anyone ever encountered something like this? Are we overlooking something? Are there changes to the OS we've overlooked? Is this an OS bug?
If you use Retrospect backup, check whether the NIB files have been caught in a backup on the server.
I have recently found several applications which Retrospect cannot handle backing up the NIB files and does not let go of the NIB files until after the backup job has been stopped.

I have just started working with Swish after buying my new imac and i am working on play ground. for last 2 days i am banging my head with wall but i could not fix this problem.
When ever i am writing few lines of code, Xcode hangs and mouse turns into small colored circle when you hoverover on the xcode window. I have to quit by force every time when xcode hangs.
I tried all possible option which i could find on stackoverflow;
I draged xcode from application to trash bin, cleaned trash bin, restarted the imac, downloaded xcode from app store installed it.
when i opened xcode after installation, it opened all my files automatically and problem was still there.
Then i followed this solution How to uninstall Xcode 5.0.2 from MAC 10.9 and removed all xcode related files by using appCleaner. It cleaned all files and folder. I restarted my system and installed xcode again :( and problem is still there.
I tried to uninstall xcode with sudo /Developer/Library/uninstall-devtools --mode=all but it does not work, terminal says
sudo: /Developer/Library/uninstall-devtools: command not found
I could see that there is something wrong with this run time compiler.
and yes i downloaded and installed the xcode 6.4 beta version and problem still there.
Can any one turn my face from :( -> :)
Here is a solution which #user3344236 provids. If someone has same problem use this trick. Create an empty project and then add playgrounds file in it. It would not crash or Xcode would not hang.
Playground is in early stages and there is something fishy with "standalone" playground, If you create swift file with File->New->PlayGround, there is high chances that Xcode will hang and you can have same problem what i had for 2 days.
A little late, but I have run into similar problems with the latest XCode (7.2) on Yoesmite. This is espcially annoying when you are, for example, writing up a long tutorial in the editor and risk losing content because of a Force Quit situation.
The simplest workaround I have found, especially when I am initially entering all the text and code (and hence really don't want it continuously trying to execute) is to insert the following at the top of each new file - removing it when I am ready to autorun the code.
don't execute
It can be any text, as long as it doesn't parse. The playground environment won't try to run while there is a syntax error in the file. But you still get all the context-sensitive help and auto-completion magic to aid in your writing.
I recently made a mac application using objective-c in xcode, and it works fine on my computer (archiving it as an application through Xcode). But when I move it over to another computer via USB (I moved the .pkg file that I generated through Xcode - this usually works fine) the images do not display.
I checked, and when I right clicked to show the package contents of the application, the correct images were there, with the correct names. I also checked and in the Build Phases page in Xcode, the images were there correctly in the Copy Bundle Resources.
Is this a permission issue? Or is it not recognising the files for some reason?
Just to clarify, this worked on the computer I compiled it on, without extra files. All the images necessary are in the package.
Also, the application was not frozen or lagging in any way I could see or notice, so I do not think it was because of a slow processor.
If this helps, the mac it worked on was a 2013 Macbook Air running OSX 10.9, and the mac where the images did not display was a 2010 iMac running OSX 10.8. The application is able to run on OSX 10.8 normally (The Deployment Target is 10.8).
When I open it on the iMac, the application just shows with the default gray background without any images, only text, buttons etc. (I am using a textured window with:
[NSColor colorWithPatternImage:[NSImage imageNamed:#"backgroundImage.jpg"]]
to have the image, as well as image wells).
Also, I am not sure if this is significant, but I went onto Activity Monitor whilst the application was running without images, and I could not see my application on the list, even with a search. (I don't have too much experience with this, so not sure if this is normal)
Thank you, any help would be appreciated.
I am learning about Objective-C/Cocoa and have downloaded the source code to a popular TeX typesetter and loaded up the project in XCode to play around with it. Compiling fails, and all of the error messages I have seen (so far) have to do with something called NSSharingServicePicker not being recognized. I gather (from this SO question and this Apple documentation page) that this is a class not available in 10.7.x. It therefore makes sense why the code won't compile on my Lion machine.
My question is, I guess, why I am able to run the downloaded package of TeXShop on 10.7 at all? (According to the website, this version is for OSX 10.7 and up.) I am interested in making a few minor changes to this project; am I not able to check my changes/compile unless I'm using a Mountain Lion machine? Is there some kind of update I can download for coding/compiling purposes?
Assuming you are using Xcode 4.6.*, you should be able to set your project to use the 10.8 SDK and get past the compile errors. (That's the "Base SDK" build setting.)
I have an OSX application written in Objective-C/Cocoa using xcode. The application is quite finished, tested and sold on the App Store.
I haven't worked on this application for some time and recently, I rebuilt it using xcode 4.3.3 on my OSX 10.7.4 and I noticed that while it builds just fine, there are some very strange visual glitches when running the application that were never seen before and occasionally, I get EXC_BAD_ACCESS when closing the application. All these seem to be related to the PDFKit framework I am using. I am unable to debug these problems since the glitches are just visual (nothing I can check in code) and EXC_BAD_ACCESS exception comes from internally allocated objects not related to my code.
The code itself haven't changed, I tried previous revisions of the code and they all exhibit the same strange behavior now. I tried running an old binary I have of the application (compiled couple of months ago) and it works just fine. Then I tried building it with previous versions of xcode, down to 4.2.1 (which I know was ok when I submitted the app to the app store) and the problems still occur.
Then I suspected this may be something specific to my environment so I built the project on different machine also with xcode 4.3.2 and OSX 10.7.4. Same results, the problems are still there.
So now I suspect that it has something to do with the OSX 10.7.4 update since this is the last thing that was changed between now and when I was able to produce a good build of the application. I am pretty puzzled to what to do next and how to identify the cause of this problem. I have an old binary that is working fine and I have a newly compiled binary of the same code revision that has problems.
Is there any useful information I can get from the difference of these binaries? What can I do to determine the cause of these problems? What can I try next?
Thanks!
NOTE (update): I stated it above but I want to make sure it is clear. This is a Mac OSX Cocoa application, not iOS.
just reset your simulator then try.
I hope you check the ARC information
go to your project Target set build settings --> Search Paths-->Always Search User Paths Set Yes.
And check your all class variables different from one another.
Xcode--> preferences-->Documentation check installed core Libraries (or) install it
like that
Xcode--> preferences-->Components check required component installed or not
check these things in your project.
Are you sure your customers are not having the same problem? Since you have tested the application on a different machine you probably do not have corrupt libraries installed (unless you did not install from scratch but used some migration tool?), so that is probably not the problem.
Most logical explanation to me would be that your customers also have this problem but they haven't reported it yet. In that case, you probably have a memory problem and there are techniques to attack that.
In any case, eliminate all the parameters that you can eliminate to simplify the problem. Deconstruct the application until the problem does not occur anymore or reconstruct the application in a different project until the problem occurs again.
It sounds like a nasty one, but you'll get there in the end, with patience and perseverance :)
First of all, you need check and verify the build log for suspicious compiler warnings.
For EXC_BAD_ACCESS, XCode analysis will give useful information.
You could try 10.6 or 10.5 (need manual installation) SDK. Or restrict the deployment target to 10.5 or 10.6.
I will answer my own question (since none of the above answers really answer it) so anyone with a similar problem might have a hint. I was not able to understand why exactly this happens but I'm pretty sure this is not a problem with my code but rather some glitch on Apple's side. And there is a workaround.
First, I compiled Apple's sample "PDF Annotation Editor" project on my Lion 10.7.4 and while the functionality is obviously different from my project, it also exhibited similar glitches with the PDFView display that my project does when compiled with 10.7.4
Then I proceeded to building a fresh clean system on new hard disk. Intalled Snow Leopard and upgraded to 10.6.8 and ONLY installed xcode. Compiled my project (the source code always stays exactly the same) and everything works fine. No problems seen in the compiled project.
Updated my OSX to Lion 10.7.4 and xcode 4.3.3, same source code. The problem is there after I compile it. I am pretty sure that if I tried 10.7.3 first, I would not see the problem as I remember it only starts with 10.7.4 but Apple doesn't provide any reasonable way to update to 10.7.3 first or downgrade to it after 10.7.4 is installed (shame on them, not very developer friendly!).
So, the problem appears in 10.7.4.
Then I installed the pre-release version of 10.7.5. This was the only thing that was changed, same source, same xcode. To my surprise, the compiled code works flawlessly now and the problems seen with 10.7.4 are now gone!
So my workaround - wait for 10.7.5 release before working on the project further. Hopefully Apple won't screw it in the future with Mountain Lion. I don't think I am going to try and debug it further or submit a ticket to Apple, going to be a tough case to explain.
Thanks for the responses.
I recently had the MacBook I'm using to develop an app (for work) rebuilt. Xcode failed to launch and there were a number of issues when running 'verify permissions' on the disk. I copied the project to a USB stick and prepared to have the machine re-imaged. Now I have it back, I've re-installed Xcode, copied my project over and it opens - great. I started some alterations to the storyboard and tried to run it in the simulator, at which point it seems to crash and returns me to the Xcode window, debugger running.
I've tried to step through the 'problems' but I can't find anything wrong. This was a working, simple project (based entirely on a storyboard approach, very little code yet as I've been building an interface that was acceptable) and the storyboard still opens fine, all the segue's seem intact etc. It just won't run. I've tried it on another MacBook (running Lion) and it also failed, complaining about 'NSBundle' and 'MainStoryboard' (I'm sorry, that machine is at home and I don't have the exact message) - yet for all intents and purposes looked fine.
The build settings etc all verify and it builds with no issues. The app is stored in a different location on the disk to where it was originally, so perhaps some of that information is stored somewhere and needs to be reset? I've tried this: XCode 4.2 MainStoryBoard Not Found with no change.
Short of me scrapping this and starting afresh, is there anything I can do/try to salvage it? It's not a huge amount of work (probably a day or so, mainly adding text/images to the views) but I'd like to try and save it, hopefully understand a bit more of what's happened? Short of thinking the drive was corrupted and also corrupted the project somehow before I made the backup I'm at a loss.
Any pointers appreciated!

The storyboard file doesn't seem to be getting put into your application bundle. Select it in the project navigator in the left-hand panel, and check that there is stick against the target in the file inspector in the right-hand panel.
Also, it sounds like you are not using version control. Use version control! If you had been using version control, you wouldn't have had to worry about moving the files from computer to computer, you could roll back to a working version, and you could easily see what the differences are between the old working version and the new broken version.
check the following settings in the xcode: and make sure to clean before building the app and running.
