when try use integer variable timer interval in nstimer in swift " argument "selector in call" code :

var count = 3 var timer = nstimer()   @ibaction func playbuttonpressed(sender: anyobject) { timer = nstimer.scheduledtimerwithtimeinterval(count, target: self, selector: selector("result"),userinfo: nil, repeats: true)  }

if put 3 instead of count works want able give user advantage set interval himself.

the nstimer.scheduledtimerwithtimeinterval takes double first parameter. try using:

var count: double = 3.0
