GM release of Xcode 6 compile

My case was a little bit different and it involves enums and optionals. For the simplicity lets define

enum Animal {
case Dog
case Cat
}

func exampleAction(animal: Animal) {}

exampleAction(.Cat)

It will run OK. However as soon as I made the argument optional the error started to appear. So this code won't work:

func exampleAction(animal: Animal?) {}

exampleAction(.Cat)

To make it work I had to add explicit enum name in the method call. So the following code worked again:

exampleAction(Animal.Cat)

I think the real problem is there are too many errors, so the compile tell you only a confused error code.

But you can always open the every source code file, in there you can find the detail error information and correct advice.

Good luck!
