Swift inline conditional?

If you're looking for a one-liner to do that, you can pull the ?: operation out of the string interpolation and concatenate with + instead:

let fileExists = false // for example
println("something " + (fileExists ? "exists" : "does not exist"))

Outputs:

something does not exist

You can use the new Nil-Coalescing Operator, introduced in Swift 3. It will return default value if someOptional is nil.

let someValue = someOptional ?? ""

Here, if someOptional is nil, this operator will assign "" to someValue.
