swift - Start the transition after 5 seconds -

-

hello how make transition

let transitiontype = sktransition.crossfadewithduration (2.0)

started after 5 seconds?

my code: 

let nextlevel = level2(size: size) nextlevel.scalemode = scalemode let transitiontype = sktransition.crossfadewithduration(2.0)        view?.presentscene(nextlevel,transition: transitiontype)

you use skaction.waitforduration combined skaction.runblock in skaction sequence:

let wait = skaction.waitforduration(5) let action = skaction.runblock {     view?.presentscene(nextlevel, transition: transitiontype) }  self.runaction(skaction.sequence([wait, action]))
