Optional @objc property

[paiv]

Trying to mock this protocol:

@objc protocol Example {
    @objc optional var ignore: String { get }
}

Generates mock class with compilation error:

     var ignore: String {
        get {
            return cuckoo_manager.getter("ignore",
                superclassCall:
                    
                    Cuckoo.MockManager.crashOnProtocolSuperclassCall()
                    ,
                defaultCall: __defaultImplStub!.ignore)
//                                              ^
// Value of optional type 'String?' must be unwrapped to a value of type 'String'
        }
        
    }
