'unresolved identifier' for return value of Type Method in Swift

I'm trying to access the return value from a Type Method in one file from another file. To wit:

file_1:

class LetterView: UIView {
    class func testFunction() -> CGSize {
        return CGSizeMake(100,200)
    }
}

file_2:

class AnotherClass {
    func callTestFunction() {
        var result = LetterView.testFunction()
        print("- breakpoint here - ")
    }
}

I get an Unresolved Identifier error on var result if I put a breakpoint in the debugger and do a po result. However if I change the return type of testFunction() to be an Int (say 2) and return that instead, then the function call works as expected. Color me confused.

Is the second file importing UIKit as well? Also, you should update your example from function to func. This all works in the playground which leads to UIKit missing.

There could be a few possible issues.

One of the classes has a Testing target and other one doesn't. You have to even include all of your classes in the testing target or none of them.

If it's Objective C class, check that the class is in ObjectiveC bridging header file.

If it's NSManagedObject subclass. Add @objc(className) before the class declaration.

If it's part of a different framework, make sure that the class or function is public
