I have two optional numbers that I add. Right now it looks like this:
if let a = optionalA {
if let b = optionalB {
return a + b
}
}
return nil
For methods, there's the more convenient optional chaining syntax, like optionalA.?method syntax. Is there an equivalent for arithmetic operators that would return nil if either side was nil?
It's possible to create an operator +? that does just this like this:
infix func +?(a: Int?, b: Int?) -> Int? {
if aa = a {
if bb = b {
return aa + bb
}
}
return nil
}
but I'm wondering if there's another, built-in way to do that.
