I'm pretty green, but I'm trying to modify a simple program to fit my own needs. You may remember the "BirdWatching" app from "Your Second iOS App: Storyboards" in the iOS Developer's Library.
Anyway, I've refactored most of the names, etc., successfully (it still worked), but then I tried to get rid of a file that kept appearing, even though its name had been expunged (or so I thought) through refactoring. Shows up in the Assistant Editor, right next to the file to which it was refactored.
Now I've got a mess. I tried to move the entire project into it's own folder, but now the compliler won't recognize the info-plist file (says it doesn't exist, and two other files are showing up in red, depending on their position in the navigator. However, it's the WMDG-info.plist that the complier complains about. Specifically, it appears to be following the old path to the file, even after it's been moved and re-added.
I've tried quitting and restarting xCode, re-adding the files, etc. I've searched under every keyword I can think of, but can't find a solution.
Please help!
Thanks!

I have a Xcode project I got from another developer. Initially when I opened it it has a bunch of errors (most of which were un-updated frameworks). I got it to work after a while and I fixed it. I want pass it back to the manager since I'm leaving uni in a few months. I copied it over to my friends Mac to see what would happen if I just took the project and all it's folders and made it a zipfile. It didn't work for some reason. It gave me an error:
error: using bridging headers with framework targets is unsupported
But why did that come up? I mean it's the same code on the slightly different versions of Xcode (13.1 versos 14.1) but I doubt there was a massive change between the two that would cause this. I want to be able to pass these app later in the future without having to care about this stuff. I made a GitHub (link below) would cloning that work? Also the laptop I chose was just a fresh reset. Would it be due to not having coco-pods installed?
I feel like I could go through and fix it all on that laptop and document that but then I'm afraid that every time I put it on a new one it would come up with random errors every single time making my documentation moot.

With big help this was Fixed.
Things that fixed it.
Having the correct version of Xcode
Turning everything from absolute path to relative
Lots of other code fixes. But those are my project specific.
You don't need bridging headers in framework. Use should have something like "YourFramework.h" where you can import your .h files.
I wanted to release an app I worked on and quickly change the project name. I usually duplicate projects before doing things like this but this time - because this procedure always worked on Xcode as I found it way more reliable than e.g. Eclipse - I didn't, which I immediately regretted.
Opened Xcode again and now I am seeing this
I guess all the linking is gone now which is why Xcode doesn't "find" the files anymore. Renaming the remaining project stem to the old name gives
couldn’t be moved to because an item with the
same name already exists
and also manual renaming of folders won't work as the .xcodeproj is gone.
The project is written in Objective-C, and all the classes are still persistent, but the effort of adding all the xib's, referencing the outlets, setting architectures, etc will become the nightmare of my life. I do have a half-way recent backup but everything I did to make the app store-ready today will be gone.
Any ideas on how to rescue my project?
EDIT: What Xcode is now showing on the welcome screen is a project called "project" (literally) and it has the usual compass icon but with a white instead of a blue background referring to the path <project folder>/<new project name>/ and below that "white" project there is a folder icon with the new name pointing to <project folder>.
I also made a snapshot before, of course it now says "Unable to read snapshots" in the "restore from snapshots" window.
Ok what I now did is renaming ALL references from the old project name to the new one. I even changed file names. I used Xcode's CMD+SHIFT+F and TextWrangler's "replace" function and thankfully I still had the .xcodeproj from yesterday's backup so from there I could copy it into the new project and rename stuff. There are still some things that don't work perfectly, for example auto layout doesn't "stretch" contents over the screen (it stays on iPhone 4s size, even on 6 plus simulator), I needed to set the scheme again and Launch Images / Icons got lost but I can look over that. The only thing I am afraid of now is that the final build might miss out a symbol or something like that so I eventually have a corrupt file in the App Store, but man it's a beta version, how much worse can it get anyway?
Thanks to everyone recommending me to even backup the broken project, I did this even before you said it but because I think it's a valuable advice I wanted to put it in my answer as well.
It's a shame that stuff like this can happen, I've been backing up my work on a daily basis and my project never got corrupted - until now.
Xcode 6 never gets past "Loading" when I try to create a new project. I actually was able to create a new project yesterday, but I decided to just ditch it completely (deleted). Clearly there must be a bad file somewhere, possibly related to the project I deleted, since I also see the same stalling behavior now with Xcode 5.1, which has worked fine for creating new projects in the past. Xcode 6 has worked fine when starting with an already existing project and still appears to do so. I did not see this exact problem in your data base, though one person saw the project creation freeze before reaching the stage I get to. Their solution was to delete Xcode and every possible file related to it, which I'm a little squeamish about, since I don't want to affect existing projects, and don't have an understanding of what the various files are for.
Deleting the DerivedData of Xcode should fix the issue. You can do this by heading to ~/Library/Developer/XCode/DerivedData (with a Finder window open press cmd+G) and deleting all the subfolders of it.
This is embarrassing, but if it could happen to me, maybe it could happen to someone else. The problem was that the window that came up after the second step in defining the type of project to be created, the one in which you choose where to save the project's files, extended off the bottom of the screen, so that only the very tops of the buttons were visible. Eventually, I realized the one to the far right might be the one to click to continue. Which it was. Feel free to delete this question.
First of all, I've never worked on iOS, so this may or may not be a stupid question, I don't know :)
I have an iOS App, and I need to run it.
In the 'Project Navigator' I have a folder/package called 'Reuse and Platform Libraries'. Inside, I have another four folders but 3 of them seem like missing.
I am not sure if this is the case. I've tried googling their name but without results so I assume they are not some open source libraries.
Can someone clear this up for me? Do I need to install some XCode packages?
Thanks!
I suggest you search the folder of the project for those files, sometimes when copying a project the paths get screwed up because they were set as absolute paths and not relative paths.
If you can't find the files, it's most likely that the library is a private one used by the previous developers, and usually kept out of the project folder so they probably forgot to send it along. I'd suggest simply asking them to send the files over :).
There is also a slight chance they are not needed to run the file, in which case, just deleting them from the sidebar should make the project run.
I'm at a complete loss as to what I did to cause this:
For the second time since I started using XCode about a month ago (my first time seriously using it after taking one class several years ago) I try to run my project and the next thing I know I have errors because I have duplicate references. I looked at the project and it appeared that most of the files in my project had duplicated themselves, however I discovered that they are not duplicate files just duplicate references. This happened to me today when I tried to build on an actual iphone for the first time but it also happened to me a few weeks ago while using the simulator. Neither time do I recall doing anything unusual. I have built and tested the project probably 100+ times and normally all goes ok. I was able to fix it the first time but I think I have made it worse this time and am probably going to add the files back into a new project. My co-worker also mentioned this happening to him (he has about as much experience with xcode as I do). He told me he ended up with files nested in folders (groups?) nested in other folders about 20 deep.
My question is this: Does anyone know what I may have done to cause this. I would really like to avoid this problem in the future since it is proving to be quite a headache. Any advice would be greatly appreciated.
E.T.A. xcode version 4.6.2 (possibly an earlier version the first time it happened)
Try this instead:
Highlight all the duplicate files
Right click on one of the files and press "Delete"
When prompted for which delete option, click "Remove Reference"
Also you asked for "any advice".
If you aren't already using git source control in your Xcode projects, start now.
You can spot many mistakes like this earlier and fix them more easily using git.
When you add files as a copy, the Xcode project navigator shows added files with an A and modified files with an M.
If the file is inside a closed group folder, the folder shows an A.
If you add a reference without a copy the project navigator won't show an A but MyApp.xcodeproj will show M.
In Xcode you can discard a change before committing it.
In the case below, you would discard changes to all added or modified files.
Typically you review and commit changes frequently.
Using a gui tool such as SourceTree, you have a good chance of spotting an accidental change before you commit. For example, you can see changes to the project file.
If you accidentally commit an unintended change, you can go back later and reverse a commit.
By committing frequently, you have more control over which changes you undo and which ones you keep.

I had the same 20 deep nesting of my main folder of images. If its not a bug its very strange behaviour. I just backed it all up !! Then I opened the folder in finder, found the point at which it was starting to nest and deleted it.
I did a rebuild, but I don't think Xcode even noticed. It made no difference to the size of my app so Xcode was not putting unnecessary files in the binary.
This happened to me when I imported a file. Suddenly I had two nested directories containing what looked like copies of all my files. The compiler complained about duplicate classes.
I found a solution, but it's a ball-ache and a time sink.
1: Click on your project in the navigator to open up the project settings in the main view.
2: Open the 'Compile Sources' accordion entry.
(This allows you to see which files are being used in the compilation process.)
3: Find any duplicates in here and delete them.
(At this stage your project should compile again.)
4: In your navigator view, slow-double-click one of the files that's duplicated there. This should allow you to rename it. Change the name (not the extension) slightly.
5: You should notice that the copy becomes red. Select it and hit delete.
(This avoids the delete operation removing the file from the 'Compile Sources')
6: Rename the original file back to its original name again.
7: Repeat from 4 until done, or until bored.
8: Explain to your boss why a simple copy change took half a day.
This process can be optimised up by first renaming all duplicated files, then deleting the duplicates all at once. However this means that you can't test for successful compilation between steps, which allows you to narrow the culprit down to a single file. And takes even more time.
If compilation fails, ensure all the files you need are still in the 'Compile Sources' section, as this process can cause them to be lost from there. The compiler will normally give some reasonable errors about missing classes and variables, but a missing AppDelegate will produce a more confusing error.
