  • 0

when i compile my app, Xcode just says “Attaching to Projectname…” and gets stuck there.
The debugger just prints this out:

error: failed to attach to process ID 0

I tried to clean & build again and it still doesn’t work out. I googled but couldn’t find anything helpful.
How can I fix this problem? Thank You!

    The solution for me was to delete everything Xcode has generated earlier:

    • the App on the Simulator…if this is not possible because you cant
      reach the Homescreen, you can delete the App directly under
      ~/Library/Application Support/iPhoneSimulator/6.0/Applications
    • delete the Derived Data in the Organizer under Projects or directly
      in ~/Library/Developer/Xcode/DerivedData
    • clean the Build Folder by choosing “Product” in the MenuBar and click
      while you press the Alt-key on “Clean Build Folder”
    • Restart Xcode
