IOS app with framework crashed on device, dyld: Library not loaded, Xcode 6 Beta

crashdyldframeworksiosswift

This crash has been a blocking issue I used the following steps to reproduce the issue:

  • Create a Cocoa Touch Framework project
  • Add a swift file and a class Dog
  • Build a framework for device
  • Create a Single View application in Swift
  • Import framework into app project
  • Instantiate swift class from the framework in ViewController
  • Build and run an app on the device

The app immediate crashed upon launching, here is console log:

dyld: Library not loaded: @rpath/FrameworkTest03.framework/FrameworkTest03
  Referenced from: /var/mobile/Applications/FA6BAAC8-1AAD-49B4-8326-F30F66458CB6/FrameworkTest03App.app/FrameworkTest03App
  Reason: image not found

I have tried to build on iOS 7.1 and 8.0 devices, they both have the same crash. However, I can build an app and run on the simulator fine. Also, I am aware that I can change the framework to form Required to Optional in Link Binary With Libraries, but it did not completely resolve the problem, the app crashed when I create an instance of Dog. The behavior is different on the device and simulator, I suspect that we can't distribute a framework for the device using a beta version of Xcode. Can anyone shed light on this?

In the target's General tab, there is an Embedded Binaries field. When you add the framework there the crash is resolved.

Reference is here on Apple Developer Forums.
