You can use this syntax:

dispatch_async(dispatch_get_main_queue(), {

However, when the last argument is a block, Swift lets you put it outside the parentheses. This makes the function seem more like a control structure (like a for or if statement). Thus you can do this:

dispatch_async(dispatch_get_main_queue()) {
