md5: bff6c6663d4a3ebc6a32c42b59ea0a80

relates to:

  • SR-2227 Cannot conform to ObjC protocols with NSDictionary as argument

Issue Description:

The following causes a segmentation fault 11 at build time using Xcode Beta 3 and toolchain 07/29/16 :

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { }

I haven't found a work-around.

Very likely the same as SR-2227. Do you have the crash log?

  1. While generating Objective-C header
  2. While printing 'ViewController' at
  3. While printing type '[NSKeyValueChangeKey : Any]?'
  4. While printing NULL type!

Okay, very similar but possibly not exactly the same. cc @jckarter
