I delete the storyboard by mistake from my app.
Where I can find it and restore it,
or I lost it?
The default storyboard filename is Main.storyboard, so that's what you should look for unless you gave it a different name. (Older versions named it MainStoryboard.storyboard, so if you are working on an older project, you might need to look for that instead.)
First, check your project folder (using the Finder). If it's there, you can drag it back into your project in Xcode, or you can use the “Add Files to …” menu option.
If it's not there, check the trash can. If it's there, you can right-click it and choose “Put Back”, then follow the steps in the previous paragraph.
Try running again your app and Xcode will create the file automatically, this worked for me.

I'm trying to localize my app.
I noticed that if I add a language every localized file become doubled.
In this way it's impossible to maintain code or storyboard so I learnt that I need Base internationalization.
The problem is that when I select that checkbox in xcode project setting it shows a window without nothing to select, does anyone know how to fix this?
Here's a screenshot
First, you need to go to your storyboard file, open the bar on the right side, and go to Show the File Inspector, the furthest tab to the left. Then, scroll down and click localize. After this, when you check Use Base Localization, you should see the storyboard appear.
This could happen if Base Internationalization was active before then disabled and files deleted manually.
Create Base.lproj folder in your project folder using the finder.
Move your main story board to it also using the finder.
fix the reference to it from Xcode.
remove app. from device, clean & build your project.
All will be back to normal.
I get this error, when try to create new action for UIButton by dragging blue arrow from UIButton to my header file (you know, this new feature of XCode 4...)
When I create action in code by myself and connect it in old way, simply by dragging from button to File's Owner, it's works well
Here's screenshot:
Make sure your .m file exists in the project and on disk. Make sure it is correct with an #implementaiton-#end block. Open it in Xcode, close it, if the error persist, restart Xcode.
Xcode is trying to write to EditPUViewController.m (in the dealloc method etc.) but could not find it.
Also, it always helps to hard-clean the project with ⌘+⌥+⇧+K.
Try this:
Open Organizer then Project Tab.
Clear the "Derived Data". Xcode should re-index your project then and code sense should work. At least worked for me.
I had a comparable problem when trying to connect an action. To solve it I manually added the IBAction and then XCode allowed me to connect from the button to the code.
Go to Xcode -> preferences -> location tab -> derived data -> clear derived dat.
I ran into this issue myself but none of the methods presented here worked for me. The error described in the question above occurred when I tried to create an IBAction in my view's header file (.h), whereas to my implementation file (.m) I couldn't even drag a line. (Xcode wouldn't even show this little popup where you can name your action.)
After trying for hours I figured that the reason why I couldn't create the IBAction was because I had removed the very last line from my .m file. Xcode automatically adds an extra empty line after the #end delimiter when you create a new Objective-C file.
Don't ask me why - but if you remove that line Xcode doesn't let you create any actions or outlets. (This is obviously an Xcode bug.)
I noticed that .m file was moved inside en.lproj folder.
Just delete (reference only) the .m file from the Xcode and moved .m out of the en.lproj. Add it again.Don't worry, you will get all your connections back.
It will fix the issue.
I recently came across this problem. I soon realized that the cause had been my own doing.
I had previously disabled XCode indexing (which used to take forever & eat up my RAM), using the below code in a terminal window:
defaults write com.apple.dt.XCode IDEIndexDisable 1
To revert XCode to its default state, i used the following line in a terminal window:
defaults write com.apple.dt.XCode IDEIndexDisable 0
Voila! All's well again..
I got the same error. Restarting Xcode did not fix it for me (I didn't want to reboot). The file was also not in the en.lproj folder (nor in the usual project folder after I deleted it from within Xcode). The fix for me was to re-create the file with a different name (Using different case in the filename alone was not enough to fix it... must be a different name entirely).
I ran into this problem when I created a class, deleted it and then created a new one with the same name. The workaround was not to reuse the name of the deleted class, but use a new one. Thus, I'd say it's a bug on the XCode side.
Remove the newly created class (don’t delete it, just remove link and then re-add it);
Save Xib file;
Restart Xcode;
You may want to delete Derived Data as well if it does still not work.
This seems because of XCode is missing reference or need to refresh manually.
In my case, removing the reference of the nib(.xib) and adding it again solved the problem.
In my case I had by accident selected the arm64 build. When compiling I got an error but I did not notice that since I was working with the UI trying to connect an action.
The error however was exactly the same. After changing to another architecture so the project compiled I could connect the action by holding the ctrl button as usual.
user2175983 and AstroCB answer's worked well for me:
Just delete all Derived data by running this command line in a terminal:
rm -frd ~/Library/Developer/Xcode/DerivedData/*
Restart Xcode
I just deleted the reference to the file in the Xcode project and then re-added the file back to project from the finder...
In Xcode 9 I had the same error after moving .m files in project from one directory to another. Deleting references to .m files and add them again did solve the issue.
I found the ANSWER. When you create a new file (Objective C files) for each view controller, you must check by clicking the box, next to your project name. So that your project includes this file. Otherwise, this error will persist, because your project hasn't connected to the file even though it created it.
I accidentally deleted my main iPhone view that was in my .xib file. This was after I had drawn my entire GUI and buttons. I was trying to delete a single button, clicked the main view and hit delete, tried to UNDO, but that didn't work.
I put a new view in the .xib file, but my original GUI appears to be gone.
Is there any way to get it back?
Thanks.
When you delete a file from xcode4, it should ask, "remove the reference" or "remove the file(physically)", but either one, try to find the file in the trash. If you are lucky enough, put back the file then add in to your project again.
Last step, start using version control system. XCode4 has build in version control system, you might give it a try (although I didnt like the XCode4 version, I use "synx", which is free).
Wait wait... back up is very important, so if you dont like version control, you can do simpler task like, zipped it the project folder, and put it in a backup folder before you start add anything new or update anything.
This looks like a bug in Interface Builder. Please file a bug at http://bugreporter.apple.com. In addition to the comments above about using version control, you can choose File->Revert to saved… to go back to the last saved version, if you haven't yet saved/closed the document.
I went back to an old project and recompiled it for OS 4.1 succesfully and ran it. I was asked to add a fourth tab to the Tab Bar, but I could not set its class to the newly added ModelsVC.h/.m. [edit: because it did not appear in the class dropdown, but the other viewcontrollers were there.]
I moved the project folder to a backup folder and unzipped a months old backup of the same project. It compiles and runs until the end of viewWillAppear for the first (default) view connected to the first tab, and then does nothing more. It is still running, but nothing is shown and nothing happens.
In the console, it says "Unknown class ModelsVC in Interface Builder file."
The problem is, that class didn't exist two months ago, so why should this way old project complain about it or even know about it?
I'd like to know where to look / tell XCode to use the .xib that is inside the project folder it is currently compiling.
And if it's path-related, how do I check what paths XCode looks in when a project is loaded/compiled?
For Xcode to run a .xib file inside the project folder, You can just open your xcode, add existing file and it is there.
I think the problem why the old project still runs is that it builds incrementally. That means when it builds the first time, the .xib file was there, and when it build the second time, it doesn't need to add and build the .xib file any more. So, in the second build, even if you delete and move out the .xib file, I think it still can build
Seems a 'sloppy copy' for whatever reason (such as a quick backup to try something experimental) of a project folder causes confusion. See this.
For some reason Xcode's Refactor is always disabled. I used to be able to activate it via selecting a class name and right clicking in the editor to select it. But now no matter what I do, it remains disabled. Any idea what's going on?
Working with Xcode 5, I kept getting "Can't refactor during indexing" when trying to refactor. Rebuilding the index seemed to hang at "Indexing - Waiting for make" forever.
I then noticed that make was already used by another process on my machine (not by Xcode). Shutting this process down enabled Xcode to finally finish indexing
Your project's index might be out of date/corrupt. In the General tab of the Project Settings window, click Rebuild Code Index and wait until it's done.
You can check the progress of the rebuild in the Activity window (Window > Activity).
I just ran into a similar problem in Xcode. I could not refactor anything in the class's .m (implementation file). The only explanation I could come up with is that it was not indexing the file for some reason, and I could not force it to reindex. The only hack that I found that worked was to copy the file to temporary location, remove it from my Xcode project, copy the file from the temp location back to my project's location, and then re-add the file via Xcode.
None of these suggestions work for Xcode 3.2 - the ONLY way is to select the file you want to rename in the left Groups & Files column. THEN highlight the name of the .m or .h in the right code view, then you can right click and select Refactor!
For instance if you're changing the DetailViewController name, highlight the actual DetailViewController.h word in code.
Note, you should also always make sure you've selected the .h file, not the .m
I faced the same thing in Xcode 11. and this worked for me:
I changed iPhone 8 simulator to generic iOS Device and it worked when it is on Generic
I'm new in iOS development,I have met this similar problem.
Xcode:Version 7.1 (7B91b),it looks like Refactor not working:
But when I put my mouse on the red circle point in the following picture，and then the Refactor working.
I think this is a low level mistake,but may be a reference for someone.
