Unwrapping Swift optional without variable reassignment

Question

When using optional binding to unwrap a single method call (or optional chaining for a long method call chain), the syntax is clear and understandable:

if le         


        

Answer 1

Here's the only alternative I'm aware of.

func someFunction(childTitle: String?) {
    if childTitle != nil {
        ...
    }
}

But then childTitle is still an optional, so you would have to unwrap it every time you use it: childTitle!.doSomething(). It shouldn't affect performance, though.
