iOS Simulator failed to install the application msg with successful build

Question

I have a Problem with xcode in running the app in simulator.

• There are no warnings/errors in the code.
• The build is success full in simulator.

Problem :
After the success full build, xcode shows a message saying "iOS Simulator failed to install the application."

Actions : result :

• On google search i got similar problems reported with following solutions :
  1. Reset Content and settings " for iOS simulator " : not success full in my case
  2. Close and restart Xcode : not success full in my case
  3. Restarting Mac : not success full in my case.
  4. Cleaning the build DIRECTORY by "cmd+shft+k" : not success full in my case.

xcode version : 5.1.1
mac OS version : 10.9
iOS version used in simulator : 7.1

Any Suggestion Would be a great help. Thanks in Advance.

I just solved the problem by reinstalling xcode from the app store.

Answer 2

There could be many reason. it's not clear from your question still you can try following

1> make sure you do not have any long task running on your main thread in didFinishLaunchingWithOptions

2> try with different simulator

3> Try after deleting derived data

4> Try it in device if possible. If it works on device than you do not need to worry. Probably it's intermittent issue and will be resolve.
