Swift: Cannot find protocol declaration

Question

I've got a really strange bug with Swift 2. I am using EventKitUI and I am able to display the view controller. When I try to add support for the delegate though I get two build errors:

Cannot find protocol declaration for 'EKEventEditViewDelegate'

Expected a type

The errors are showing in my projects -swift.h (the project mixes Swift and Objective-c).

Any idea why this is happening? Unless I'm missing something I can't see any basic mistakes (typo etc.) that could cause this.

Answer 1

Strange fix but by importing #import <EventKitUI/EventKitUI.h> in my bridging header the issue was resolved.
