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?
