What would you like to do?
A sample on unwrapping String optional using force-unwrap to return early.
func sampleEarlyReturnFunction(sampleName: String?) {
if sampleName == nil {
let anotherName = sampleName!
print(createGreetings(sailorName: anotherName))
// This code will do just fine, even the name has nil value.
