Recently created an app in Xcode and it runs fine on my computer. Sent the .app to a friend, he cannot run it

Question

Any suggestions as to why the app will launch and quickly disappear from the dock? It's a very small app with about 80 lines of code and no outside API's, libraries, or dependencies. A simple countdown app created in about an hour.

Answer 1

Have your friend run it from the Terminal window (ie ./MyApp.app/Contents/MacOS/MyApp ) and see if it prints out any helpful error message to stdout.
