Swift: Thread 1 signal SIGABRT

After upgrading Xcode from 5 to 6 beta, almost every project gives me an unexpected error after running the application. There are some other posts with this title but the error is different.

In AppDelegate.swift, sometimes the simulator goes completely black, without the error, sometimes it gives me the error on this line: 

class AppDelegate: UIResponder, UIApplicationDelegate {

In Xcode 5 I didn't had this error before, with Deployment Target set to 7.0 or 7.1.

Thanks in advance.

Solution

  • Seems like there was a bug with iOS 7.1 as target.

    Running tests on devices with iOS 7.1 installed now works. (17028705)

    Try it again with the beta 2 update
