In general this is a correct behaviour, because literals in Swift are untyped. Int does not have any initializer for a Bool so the compiler tries to find a type that might conforms to ExpressibleByBooleanLiteral for all possible initializer of Int (Int.init(_: TYPE)). This resolution decides to go with NSNumber in your case?!
The thing is, when you write Int(a > b), you’re passing a Bool and not a literal anymore. Here the compiler does not fallback to NSNumber anymore and reports you an error, because Int.init(_: Bool) does not exist. -- Adrian Zubarev Sent with Airmail Am 21.
