Closures in Swift are similar to blocks in C language and also Objective-C. The benefit is that the functionality can be passed around and use within your code. Also, you don't have to create a whole new function/method in the global scope. Neither do you need to create target-action callback. This mean, you will write fewer codes for the same functionality.
