Swift 3.1

From Swift 3, you can use String(describing:) to print out optional value. But the syntax is quite suck and the result isn't easy to see in console log.

So that I create a extension of Optional to make a consistent nil value.

extension Optional {
    var logable: Any {
        switch self {
        case .none:
            return "⁉️" // Change you whatever you want
        case let .some(value):
            return value
        }
    }
}

How to use:

var a, b: Int?
a = nil
b = 1000
print("a: ", a.logable)
print("b: ", b.logable)

Result:

a: ⁉️
b: 1000
