I have been working on a project in Beta Xcode 8 using Swift 3 and just today when I tried to build my application I found that the "Main Interface" in Targets is missing and when I try to drop down to choose nothing is there.
Checked my storyboards and they are added to the project. Checked my storyboards for entry points, those exist and are in the right place.
The project builds to a black screen. Tried removing and re-adding entry points and that did not work.
If I try to force the name of the storyboard into the Main Interface I get errors saying that storyboard does not exist, it does and it is in the project.
Wondering if anyone came across this project and has a solution.

Using Xcode 6 GM seed my code completion has stopped working. It was working the other day. I was trying to get the unwind segue work around to work. I had made an Objc header file and assigned it as a header for a Swift class.
At this point I get code completion with an Objective-c project. But, not with a Swift project.
I have tried restarting Xcode, making a new empty project.
Just go in user->Library->Developer->Xcode->DerivedData and delete the Data of folder(Derived data) and restart Xcode.
This fix from apple dev forums works for me. I have had autocomplete issues with Xcode 6.1/Yosemite.
Quit Xcode.
Restart the computer (this is to clear any in-memory caches).
Delete the contents of the DerivedData folder (~/Library/Developer/Xcode/DerivedData), precisely run, a) cd ~/Library/Developer/Xcode/DerivedData/
b) rm -rf *
(Try this if Steps 1-3 dont really work as it rebuilds the cache later on restart which takes time) Delete the contents of folder ~/Library/Caches/com.apple.dt.Xcode, i.e., a) cd ~/Library/Caches/com.apple.dt.Xcode b) rm -rf *
Now launch Xcode once more…
I experienced a serious breakdown of code completion because I had some 'notes' after the #end statement of my .m file which were as follows:
/*
NSAlertFirstButtonReturn, NSAlertSecondButtonReturn, NSAlertThirdButtonReturn
*/
These lines can appear before the #end statement without destroying code completion.
There's an easier way to delete the Derived Data from within Xcode (no need to open finder or restart):
Xcode Organizer -> Projects -> (Your Project) -> Delete Derived Data
I just recently had this problem. Autocomplete did not work ...and when i typed for example tableView.... it did not give me the different functions available.
I tried the following and it worked for me.
Xcode Organizer -> Projects -> (Your Project) -> Delete Derived Data
delete the file ~/Library/Developer/Xcode/DerivedData/ModuleCache
Restart xcode
Hope this works
Another possible reason why it isn't working is because it's not part of the target membership. To fix this, select the file you're working on. Then, go to the File Inspector and in the Target Membership section, make sure your project is checked.
Try the following - as silly as it may sound:
Change Device to iPhone 6, close Xcode, Reopen Xcode and wait for the indexing to finish.
Go to Xcode menu, then Window -> Organizer, then select Projects. Pick your project and press on delete button beside dervied data
Then restart Xcode
That solution worked with me on Xcode 6.1
If your code completion problem is only with UI classes (e.g. UIImage, UIDevice), then you just need to add "import UIKit".
Swift files will NOT have code completion for UI classes unless there is an "import UIKit".
I had the same issue but under different circumstances,
I have 2 projects in my workspace
Swift framework for iOS and OSX
iOS Project (which uses the swift framework)
My code completion works fine in iOS but it keeps failing in the swift framework. I tried all the about solution and had no luck and was killing my productivity.
Finally i figured out the solution to this problem.
Select the file you are editing (in the framework )
Select the 'utilities' tab on the right
uncheck the Mac target (just keep the target you are working for
currently)
Thats it, this solved my problem.
hope it helps someone who is in this kinda situation.
user/Library/Developer/Xcode/DerivedData Delete all the files shown in this folder. after that go to your project name and clean project then come back to the file where you wanna see suggestions. Type any word and its done.
So all you have to do is make sure, in the file inspector view on the right side, under Target Membership, the first box is checked. I'm not sure why this changes things but I'm sure someone can come along and give a more complete answer.
In my case Some File(s) were deleted in File System but were still referenced in the Project i.e. in Red Color. Just delete those from Project and everything was fine. Code Completion started working.
Also Like to point that all the above answers about Clearing/Deleting Derived Data folder seems to work momentarily but whenever there was a new pull or update the problem started again, so the root cause was the unreferenced/moved/deleted files which show up as RED in the project, they needs to be manually cleared.
Like many of the prior 'MainStoryboard missing in NSBundle' questions, I've got the same prompt but have found no issue with naming and no issue with if the storyboard exists within an area XCode likes.
All the pointers lead to the same file, I've changed my .plist a good 5 times to make it responsive to the same call as found in Build Stages. Now I'm all kinds of tired of this crap because I just want to program, not debug compiler screw ups.
It happened in an instant and now I've been a day and a half without an interface that works. How should I proceed?
I got the following similar error in XCode 4.3.3:
Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: 'Could not find a storyboard
named 'MainStoryboard'
I fixed it by doing the following:
Make sure your -info.plist has Main story board file based name = MainStoryboard
Right Click on your Story Board file in Xcode and select Delete then References Only
Right Click on your project and select Add Files to [Your Project]
Navigate to the story board file, found in the en.lproj folder in your projects directory and add it
Clean, Recompile and Run and you should find it works.
Got the idea from this SO post: XCode 4.2 MainStoryBoard Not Found
Just as a reference to other first timers like me reading through all the SO questions about missing storyboards:
Don't put ".storyboard" at the end of your file name in your plist file. It should look like this:
Main storyboard file base name: MainStoryBoard
When you create a new *.storyboard file, Xcode (version to date) doesn't automatically add it into your build resources. To fix this you must add the file under "Copy Bundle Resources".
Select the Xcode project icon and navigate to: Targets > Build Phases > Copy Bundle Resources
Click the + button at the bottom to add the storyboard file.
After cleaning my Projekt i have every time this Problem......
My solution is:
move the Main.Storyboard intro trash.
Then "Add Files" select your soryboard, after moving the Main.stpryboard from trash zo your desktop.
and, voila. The Error ist gone.
Considering that there is not too much information about your problem, My best bet would be to go to the package Info, and see if the Main Storyboard is set to whatever your main storyboard is.
As of iOS 9 use just "Main" for storyboard name, worked for me.
Ralph Willgoss's steps didn't work for me. I managed to solve it by copying all the viewcontrollers in the storyboard, deleting it (Move to Trash, not Remove Reference), making a new one (rightclicking the project folder and clicking New File, selecting Storyboard) with the same name as the one I deleted and then pasting the copied contents into it.
Please show me how I can add and implement the libPusher library to my Objective-C iOS project
This is my first post on StackOverflow
I've just started working in Objective-C iOS app development for a company that I co-founded with a couple of colleagues. Our first app needs to have the libPusher library implemented in its porject. Right now, I'm at a crossroads completing the following task of adding and implementing it on Xcode 4.2:
Simply copy libPusher-combined.a and the contents of the headers directory into your Xcode project..
Source: http://github.com/lukeredpath/libPusher/wiki/Adding-libPusher-to-your-project
What does it mean by "copy"ing those files, and where should it be copied to? Can anybody who has experience with libPusher give me specific details as a list and source code on how to execute this so I can understand it better? I would truly appreciated any help, it will get our company up and running for us getting our app functioning and ready for reviewing submission to Apple Developer staff. The link I've provided will tell you more on what I'm talking about, if I need to specify anything I'll create a new post. Thanks!
What "copy" means in this context is that you want to drag and drop the .a (library) file and the header files (all the .h files) into your new Xcode project (to be precise: the file inspector is the list of files along the left side of the workspace window).
To copy anything to an Xcode project, find it in the finder, highlight all of the files you want to copy over (or just take the folder it comes in), then drag everything over the Xcode icon in the dock.
If Xcode is full screen (lion), the icon will kind of blink, then enter Mission Control mode, you then hold the files over the correct project and drop them into the Xcode file tree.
Make sure that your application is checked as a target for those files!!
If Xcode is not full screen, just drag the files or folder into the Xcode file tree and they will be added.
To link to a static library, just navigate to the name of your project>Info>Framworks. Click the plus, then select your framework if it isn't already there.
Assume you have two XCode4 projects
App
Library
Since the Library is active developing, so new headers might be added from time to time, code might be changed from time to time.
Even I can drag the Library XCode project into the App XCode project, I still need to copy the headers manually.
Are there any easy way, rather than copy the Library into the App library folder, I can develope the codes on two projects at the same time, e.g. debugging.
A few recommendations after beating my head against a wall:
Try creating an Xcode 4 workspace containing the 2 projects. It seems to work better than having one be a sub-project of the other.
Instead of copying the headers, add their path to the "header search paths", then select "always search user paths" (both in build settings).
To get started: Xcode 4 workspace docs
I have just upgraded to the new Xcode 4 and the code is not colored has it ought to be.
For instance, the string NSString is not colored in my custom code, but when I switch to Apple's code (NSString.h for example) everything is well colored.
How can I fix that?
It's a known bug with the latest XCode. This happens with some projects which are migrated from XCode 3.X to the new version. For some people it seems to help to go to the organizer, and in the project tab delete the derived data for the project where code sense does not work correctly.
If you have a small project, it might also help to create a new project in XCode 4 and import the files from the XCode 3 project.
Update: XCode 4.0.1 made the situation a bit better, at least in some of my projects I have syntax coloring and code sense back. But it's still far from fixed.
Update 2: XCode 4.0.2 did not change much. It seems that the problem is related to subprojects, specifically static libraries. According to comments of this blog post some people were successful by changing header search paths from relative to absolute paths, e.g. instead of Foo/Bar use $(SOURCE_ROOT)/Foo/Bar. This together with switching all projects to XCode 3.1 format and to use LLVM 2.0 fixed a lot for me as well. It's not perfect yet, but usable.
Update 3: After converting the sub projects to independent projects and putting them in a workspace (aka the XCode 4 way) I have now full syntax highlighting and code completion back.
My current environment is now a XCode 4 workspace with each projects being 3.1 compatible (as opposed to the default which is 3.2), LLVM GCC 4.2 (system default) and the header search paths are still absolute (using $(SOURCE_ROOT)/.../).
I used undefined Macro, But those macros defined in Preprocessor Macros in build settings. So the xcode4 didn't generate any error for that undefined macro.
Steps taken to resolve.
Removed undefined macros wherever I used those undefined macros.
Removed duplicate definitions of Marcos.
Removed duplicate Resources. (I'd added same (many Thumbs.db files) files into the project.)
Clean & Build.
if still you are not getting the color then, please relocate your project to some different location, I changed to my Desktop location.
After these steps I got the color in my eyes.
But its very bad issue. I sucks lot of valuable time. I think these steps may help you.
Thanks.
I had the same problem with mine. Its a cocos2d game with box and chipmunk. It was a hell of a mess getting the project to recognize and find the user search paths in the first place so I wasn't about to mess with those.
What I wanted to point out is that I DO HAVE recursive paths and I do have relative paths and I still got the issue. It happened when I added a new version of a 3rd party SDK I was using. It was Testflight 083 which I updagraded to 1.0. I erased my old version but only removed references. Then I manually deleted it from finder. Imported the new SDKv1 folder and readded it to my project and removed the old SDK0 folder path leaving only the newly added SDK1 folder path. For some reason I noticed that even though in v083 I had used a #import in my Prefix.pch file, it still wasn't recognizing a call to a method from AppDelegate. Which means the #import in Prefix.pch for some reason was not working. I had to add #import to my AppDelegate file individually. This gave me duplicate #imports as Jeeva said above. That sounded an alarm in my head.
So the solution was to go and effectively remove the duplicate #import in Prefix.pch therefore only leaving the one in AppDelegate. It reindexed and CodeSense works again. Thanks Jeeva!
This issue was driving me insane, and I had given up hope of fixing it without some ugly hack on XCode's configuration. I passed through this very forum thread a stack overflow of times. Then one day, I happened to accidentally fix it. I'm not sure if you need all these steps, but I've found this a sure-fire way to fix XCode's indexing issues:
Clean your project (Command-shift-K)
Open organizer, close your project.
Under the "Projects" tab in organizer, remove the derived data for the project you want to reset.
Quit XCode
In the terminal, run:
sudo mdutil -a -i on
This seems to reset spotlight indexing (I don't know much about it because I don't use spotlight).
When the command finishes, Spotlight will have to re-index. Look up to see a little dot in the magnifying glass for your spotlight's icon. When the dot leaves, spotlight has re-indexed. You can check the progress by opening spotlight.
Re-open XCode, and wait for it to re-index all your files.
Build the project.
On build success, you should now have appropriate syntax highlighting again. I hope you guys find this little discovery as useful as I did :)
EDIT:
I should probably add that the syntax highlighting sometimes seems to re-break when the debugger hangs the simulator during app launch. I just try to avoid this by being more careful about letting the process hang.
EDIT2: (sorry first contribution)
Works on XCode 4.6 and 4.6.2.
