I just found an equivalent to Swift’s if-let construct, and thought to share it 🙂

Swift:
[swift gutter=”false”]
if let result = computeResult() {
// do something with result
}
[/swift]

Objective-C:
[objc gutter=”false”]
for(SomeClass *result = [self computeResult]; result != nil; result = nil) {
// do something with result
}
[/objc]

You no longer need an extra line to declare the variable, and also the variable is visible only inside the if branch. Just like in Swift 🙂
