Xcode 4 hangs at “Attaching to (app name)”

Question

I just upgraded to Xcode 4 and for some reason my app won\'t run in the simulator or iOS device. It was working perfectly in Xcode 3, but all of a sudden now when I press ru

Answer 1

I noticed it happened to me when I edited the scheme from Build Release to Build Debug. I changed back, and it worked :)

Answer 2

What worked for me:

• Launch "Monitor" and kill gdb-i386-apple-darwin which was supposedly hung
• Restart iOS simulator

Answer 3

Also: make sure that you haven't included the Info.plst file in your Building Phases -> Copy Bundle Resources. If so, remove it from that list! I small mistake which could happen, but something that messes things up quite nasty :S

Answer 4

For me, none of these has worked. I realized that my project had 2 info.plist files (with two different names, like info.plist and Project-info.plist), so XCode got confused. I just removed the incorrect plist file, and it worked!

Answer 5

I really find the answer for me :)

for me,

project setting -> your target -> build phases -> validate setting -> perform

and now the problem is gone.

:)

I hope someone it help

Answer 6

I encountered this error after incorporating another project inside my new one. Make sure you delete the project that you have added's info.plist and .app
