The point of using a ? b is that a is optional, and the docs say ? unwraps a if it isn't nil, so if you let Swift infer the result type, b and the result are the same "optionalness".

Note that IPv6 scoped addresses are converted to integers without scope zone ID. I suppose to be explicit, you should write it as: let j: Int = Int(s ? "0") ? 0Īfter thinking about it some more, it isn't strange it works for the same reason the s ? "0" part of our simple example works (where s is optional but "0" is not). Returns a string representation of the IP address, controlled by an. How can I remove the '-' character from the MAC address and put this MAC address in char6. As we know that MAC address is 6 byte long. Which is kind of strange, because Int(s ? "0") returns an optional, but 0 is not optional, and Swift creates j as non-optional and doesn't complain. I have MAC address in char18 in the form of '00-13-a9-1f-b0-88'. The following works ONLY if the optional string really contains an integer: let j = Int(s ? "0")!ĮDIT: The following works no matter what is in the optional string: let j = Int(s ? "0") ? 0 Standard repr() access returns a Python statement that can reconstruct the MAC address object. That second line won't compile "Binary operator '?' cannot be applied to operands of type 'String?' and 'Int'. Instances of the EUI class are used to represent MAC addresses.
