Question

I’m trying to change my Bundle ID from the default one to the one I created in Apple’s Developer Center. But when I change the Bundle ID in the plist, then delete the app on my phone and try to run it from XCode, I get the following error:

Could not launch "MyApp"
No such file or directory (then it lists a path to the app's DerivedData folder)

Am I supposed to do anything special when I change the app’s Bundle ID?

Try cleaning the project. I prefer to simply delete the whole ~/Library/Developer/Xcode/DerivedData folder, because Xcode sometimes messes up and doesn’t clean properly.

Consider writing a simple bash script for that. In ~/.bash_profile (you might have to create this file first) add this:

clean(){
rm -rf ~/Library/Developer/Xcode/DerivedData
echo "Removed all derived data."
}

Save and run source ~/.bash_profile (or restart Terminal).

Now you can simply type clean into any terminal window and it will clean all your projects.
