if-let statement in Objective-C

I just found an equivalent to Swift’s if-let construct, and thought to share it ๐Ÿ™‚


if let result = computeResult() {
    // do something with result


for(SomeClass *result = [self computeResult]; result != nil; result = nil) {
    // do something with result

You no longer need an extra line to declare the variable, and also the variable is visible only inside theย if branch. Just like in Swift ๐Ÿ™‚
