Answer 1

Your problem is in errorCode: Int? in UserCompletionBlock.

Int is value type, and Objective C cannot represent Optional of value type, only reference types such as class will.

So you have to either:

1. get rid of optionality
2. use reference type, such as NSNumber or your own wrapper
3. drop this parameter completely
