Xcode will not open my project

3 Solutions Collect From Internet About “Xcode will not open my project”

There are a couple of things you can try, first make sure Xcode is not running ,trash the ~/Library/Cache/ folder contents, and trash the contents of the ~/Library/Developer/Xcode/DerivedData/ folder, if you what to can just find the stuff for your project in ~/Library/Developer/Xcode/DerivedData/ and trash just that. Then restart your computer.

If that doesn’t work, rename your faulty projects folder to so method like ‘ old’, create a new project of the same name, and then move all of the source files from ‘ old’ to you new project and add them. Its a bit painful I known but I have had to do this once to get a project working again.

Nothing mentioned above worked for me. So, here’s what I did instead.

Right click on the .xcodeproj file and select Show Package Contents. Then delete project.xcworkspace file. Open the project in Xcode and viola! Hope this helps somebody.

This happens to me sometimes, but with other apps. There’s no real solution to it. All you can do is restart your computer. Some other things to do is make sure you are updated to Lion and Xcode 4.
