Xcode 8 syntax highlighting doesn't work

Question

The code above has correct syntax highlighting in Xcode 7. It is mix of Obj-C + Swift:

I've updated project to support Xcode 8 and only few things was changed:

• In Build Settings Swift 2.3 support

After all the project is compiled fine for Xcode 8.

But Obj-C code integrated in Swift doesn't have any syntax highlighting and vice versa:

And there is << error type >> problem with autocomplete:

Derived data deleting doesn't help, Xcode restart either :) CocoaPods version 0.38.2, iOS 7

Answer 2

Commenting and then uncommenting the affected lines worked for me.
