[swift-users] Waiting for mouse input in a while loop (OS X)

[George King]

Hi Ergin,
Are you familiar with how events are delivered via the application runloop? Essentially, you should not create a top-level loop that waits for input; the application runloop does this for you. If you want to accumulate 50 clicks, create the counter variable in the appropriate NSResponder (or UIResponder on iOS), e.g. your root NSView or your NSViewController. Then override `func mouseDown(event: NSEvent)` and increment the counter there.
Hope that helps,
George
