EDIT: I ended up creating a new project as suggested by justColbs and moving all of my classes plus the launchscreen.xib file and storyboard file into the new project directly in XCode and it works now! Yay for bugs, and I'm never going to try to rename a project again...
I renamed my project by selecting the .proj file, going to view, utilities, show file inspector. I changed the name in the upper right corner and then a window came up and I couldn't click the rename button, so I clicked don't rename and the play button greyed out.
All that shows up in my Devices list now is Mac OS.
I tried changing the name back, and it is now saying that I don't have a launch screen image for iPhone 4 retina displays, which wasn't an issue before this change.
How can I make it so I can build my project again?

For some reason, XCode is acting up really oddly. I have been testing XCode's ability to load images with the -hd suffix, and realized that Xcode will load a file "welcomeBackground.jpg" regardless of whether it is actually in my project folder.
See, this code below will not crash when compiled. And this is the first screen that is displayed when the app loads. I deleted the file "welcomeBackground.jpg" from my project folder, and XCode still loads the file as if it were there.
This is really freaking me out. Please help?
I am 200% sure I deleted the file from my project folder even and yet Xcode does not crash on line 35.
EDIT: To repeat, things I have tried/checked
- Cleaned project
- Deleted Derived Data
- Checked for hidden files in project folder
- Deleted app from iPhone and re-run from XCode
- Deleted the files from my project folder
- Loaded another image "sadhieia.png" and crashed Xcode
because Xcode couldn't find the file (as it does not
exist), and then tried "welcomeBackground.jpg" again
and Xcode somehow finds it.
And yet, the background still loads...
In Cocos2d, if the specified image is not in your folder, it'll not crash. Instead, it'll return nil to your CCSPrite *background.I suggest you Don't use Camelcase for images. Use lowercases or underscores. Try deleting Derived Data. See this for how to delete derived data.
Scroll the project navigator down to the bottom, to "Products," then click the disclosure arrow to show your application.
Right-click the application and choose "Show in Finder" from the contextual menu that appears. A Finder window is displayed containing your application.
Command-click the title of that window; another contextual menu appears. From that, choose the folder "Derived Data." The Finder then displays a window for that folder.
In this window, you'll see a folder whose name is that of your application, followed by a long string of letters. Trash it. If you see multiple folders bearing your application's name, trash them as well.
Rebuild your project. That should take care of the issue.
This might be a slash and burn approach, but it's solved a lot of quirky project-related issues I've experienced in Xcode after attempting to clean.
Clean your project; your image file is still cached in the build folder.
Okay, I am a noob. It must be simple but I stuck here.
I do rigth-click and choose 'select file'.
After I choose the file the dialogue appears:
I want to keep my icons not in the root directory. But I can't figure out how to do this. I tried different ways, even create project from scratch...
Please help.
When you bring image assets into Xcode they will all be in your application bundle's root directory at run time.
It appears that you've added a file named "icon#2x.png" to your project at one time already. Go to the project's summary page in Xcode click Build Phases and then expand the section titled Copy Bundle Resources. There you'll find the reference to the resources that will be copied to your bundle at run time.
More on bundle structures here:
https://developer.apple.com/library/mac/#documentation/CoreFoundation/Conceptual/CFBundles/BundleTypes/BundleTypes.html
Anyway, the way I've done this in the past is to:
Remove the existing image duplicate from Xcode and from the folder structure in Finder.
Add a new folder in Finder call it "/AppIcons" (or whatever).
Copy all the app icons to that folder in Finder.
Drag the "/AppIcon" folder into your XCode project. I typically put images in an "/Images" subdirectory in the Xcode project. Again you can put it wherever you'd like.
In Xcode on the project summary panel, add your app icons from the folder "/AppIcons" by dragging / dropping or by right clicking and adding them as separate files.
Alternatively in the past when I've had problems with this sometimes Xcode will copy the app icons to the root project directory. If that happens, I make sure that I have the "/AppIcons" folder structure on disc (in Finder) and in my Xcode project. I add the app icons to the project, then move them to /AppIcons in Finder, and re-reference them all over again.
Your Copy Bundle Resources should then have the proper file reference. Note that my apps icons go in "/Images/AppIcons"
Good luck!
I would add the image files to your project with the name icon#2x.png. To do this right click where you want to add the files in xcode and click add file/s. Then search for your image and add them using the dialogue that pops up. - there is a check box so that you can either copy them to the projects destination folder which will copy them into you project folder or leave it unchecked (inadvisable) which would reference it's current location on your HDD. Make sure the file doesn't already exist in the project before doing this!
EDIT:
Sorry I forgot to mention then drag and drop the file from within xcode onto the image location box.
In XCode 4 (I'm using 4.6.2) you will get this confusing message if you've just moved the target's info.plist file, but not corrected the location at the top of the summary panel. Fix this and the icons will reappear, assuming they are added to the project, or if not you should now be able to drag them in without xcode insisting on making extra copies.
This tends to happen when you're starting a project and sorting out the mess of default file locations that xcode gives you. I like my project structure to be 99% the same as the file system structure.
This is an easy fix. If the image you want as your App Icon resides outside of the root of your project, when you get that dialog just click "Yes", and then click delete on the newly created file in the root, and "Move to Trash".
The reference is still there and works without a hitch, since the file will still be in the root at runtime
I am a newbie to iOS Development. Learnt a chapter 2 days back about using settings bundle in my apps. The tutorial also showed me how to add new plist files and images into the settings bundle by ctrl+click opening the bundle in Finder.
But the newly added items do not show up in Xcode project organizer list. Is that how it works or do we have an alternative?

Thank you guys for the replies. Actually I figured out something weird. When I added objects to the settings bundle from Finder, they did not initially show up on Xcode. I closed everything and then reopened Xcode and saw them in the bundle inside Xcode. So I guess the error was on my part expecting the objects to be added in Xcode as soon as I added them to the File system via Finder.
Sorry for the trouble and thanks for the advises.
It has to be there maybe inside any folder. When I add a file I usually add first a group (right click Add group) then there is a new folder so in the folder (example images) I right click and add a file.
It should be there, if not then right click on any folder/file in your xcode, tap on Show or Reveal in Finder, then it will take you to a place where all of your project files are placed, drag and drop from there into your project. It will not automatically pull into your project if you will add them in a folder on your disk. You will have to drag and drop into your project.
Let me know if you have any questions.

I've applied changes in interface builder for my app which has labels in it. I just changed the name and position of a label and in addition to that I changed the font of a text view in my app. When I started to run my app, the font remains the same as previous one and none of the labels are displayed in it.
Can anyone help it pls?
in Xcode try this: main menu:product:Clean
if not enough: main menu:Xcode:preferences: -> click over locations icon:
click over the little gray right arrow for derived data:
that will show you the finder folder "DerivedData": delete it.
one other thing to try: in simulator, delete your app.
quite your xcode and then again open your project . Clear your build then run your code.
You should also make sure, that the interfacebuilder file is linked to the target you are starting in simulator.
To do this, select your xib and open the File inspector. There you should see a dropdown named "Target Membership" where you can link the xib to the targets you want.
Also be sure to have the labels defined as IBOutlets in your header file and link them correctly in your xib. Easiest way to do this is using the Assistant Editor and drag the outlet to the header file.
I had the same problem - but only on the iPhone non-retina in the simulator. Cleaning the code did not help. Restarting and rebooting did not help. But removing the app from the simulator worked. Now changes to my UI show up next time I run.
To remove the app from the simulator I did it just like on a real phone. I select the app icon with the mouse and hold it down the mouse button for a few seconds. Then the icon displays a small delete icon that you can select (the app icons shakes too).
I'm running Xcode 4.1 and I've been following a tutorial about app settings. Everything has been going great up until I get ready to add a plist for a child pane that I want to add.
The video tutorial I'm watching (also using Xcode 4.1) shows the guy right-clicking the settings.bundle and choosing Add File... and then saving a file named More. In the video tutorial, he ends up with a More.plist showing up in the project and also in the settings.bundle right in the same level with the Root.plist. I just get it in the project. Nothing in the settings.bundle, and I can't figure out how to copy it there.
I've also noticed that in the tutorial, in the Project Navigator, the settings.bundle has an icon that looks kind of like an outline of a shield. In my Project Navigator, the settings.bundle looks like a white sheet of paper with a corner folded down.
Anyone know what the heck is going on?
FWIW, the root app settings works fine in the simulator. I can see the stuff I set up just fine. I can click on the link to my child pane and it switches to it, but nothing that I added in the more.plist shows up there.
Any help GREATLY appreciated!!
Argh, Apple tends to change things without letting anyone know. The whole settings bundle thing is just not well integrated into XCode if you ask me.
If you ever try to localize your application, you will find that you have to manually add the localization folders to the settings.bundle.
Looks like we have to do the same thing to add child menus now, as just adding the plist file does not put it into the settings.bundle.
Here is the set of steps I just tried that worked.
Open up finder, you can right click or two finger click Settings.bundle and choose "Show in Finder".
Right click Settings.bundle in the finder window, choose show package contents.
Copy the new plist file into this the settings.bundle next to the Root.plist
Delete the new plist from the main project.
I was not able to get the text field to show up under additional .plist page.
My Fix:
Leave only 1 Child.plist file outside Settings.bundle
Navigate to Root.plist
Right click and select 'Show Ray Keys/Values'
Right click and select 'Add Row'. Add:
Key: File
Type: String
Value: Root
In Xcode 4.3.2,
Right click the Project Name in the Project Navigator, and choose Show in Finder.
In Finder, right click the setting.bundle and choose Show Package Contents.
Copy the new .plist to setting.bundle.
Back to XCode, open the setting.bundle, wilfully add one item under the Preference Items, then expand it and modify the value of Type to Child Pane.I can't upload the image, so give the link of the blog.
This problem still exists in Xcode 4.2. Creating and moving [child].plist in Finder does help thanks to John S up there.
Some additional tips.
Make sure to turn on "Show Raw Keys/Values" by right clicking inside the opened root.plist file for the "ChildPane Type" to appear. Also make sure to select "Property List Type" as "iPhone Settings plist". If you're having trouble with ordering items, just open the plist file in a text editor and move the xml elements around accordingly.
Additional additional tip: in Xcode 4.2 to explore/expand the contents of the bundle make sure to set its type to Application Bundle (via File Inspector Menu).
Same issue, waste my almost 1 hour.
1st make sure your plist format is correct.
My solution:
Delete you bundle, and re-build & run.
Now everything is fine...
