just print it
print( “\(myObj)” )
You’ll get
1) something very ordinary if myObj doesn’t implement anything special
2) the result of debugDescription if it implements CustomDebugStringConvertible
3) the result of description if it implements CustomStringConvertible
2) and 3) are protocols you implement. That’s what they are called in Swift
2.0, they were called something else in Swift 1.x but the idea is the same
