I have problems with running OSX applications with XCode. Sometimes (about 30% of the time) the application doesn't start and "XCode cannot run using the selected / Choose a destination with a supported architecture in order to run on this system." message is displayed instead.
This is NOT a duplicate of other questions, because this is not a problem with a project file (in such case the app would never run, and in my case the behaviour is random - sometimes it starts, sometimes not). This only happens with OSX applications.
XCode 5.0.2 (5A3005), OSX 10.9.3, but I had this problem since the first version of XCode 5 on both OSX 10.8 and 10.9.
Have you ever encountered similar issue?
