How to use Block in Swift?

Question

I am using block in objective C like

typedef void (^RequestSuccessCallback)(WebRequestManager *request);
@property (nonatomic,copy) RequestSuccessCallback RequestSuccessBlock;

but how to use Block in swift?

You're asking very basic questions that would only require a cursory look around the web/stackoverflow. There are plenty of good resources on blocks in Swift out there. In future, please show what attempts you have made at solving your problems, especially when they are this basic. — Rambatino

Try something like this:

typealias RequestSuccessCallback = (WebRequestManager) -> Void
var requestSuccessBlock: RequestSuccessCallback

Or something like this if you prefer a named callback:

typealias RequestSuccessCallback = (manager: WebRequestManager) -> Void
var requestSuccessBlock: RequestSuccessCallback
