Function used in selector in iOS Swift can only be in the same file? -

Function used in selector in iOS Swift can only be in the same file? -

i have created time activate on view controller. needs phone call selector, , selector, calling function.

when function in view controller file, works. if set function in swift file created in app, not find selector , error during runtime.

is possible set functions in swift in different files or not?

@ibaction func startnotificationtimer(sender: anyobject) { timer = nstimer.scheduledtimerwithtimeinterval(10, target: self, selector: "update_start", userinfo: nil, repeats: true) timerstatus.text = "started" }

"update_start" in different file.

thanks help

it doesn't matter file update_start method in, matter method in view controller class. if define in file other 1 class declared, you'll need define method in extension on class.

also, nstimer selectors should end colon (update_start:), because take single parameter (the timer) when called.
