ios - Animate UILabel text color in Swift -

how can animate color change of uilabel using swift? have seen people mention using calayer cannot figure out swift syntax.

this example of objective-c

calayer *layer = myview.layer; catextlayer *textlayer = [catextlayer layer]; [textlayer setstring:@"my string"]; [textlayer setforegroundcolor:initialcolor; [textlayer setframe:self.bounds]; [[self.view layer] addsublayer:textlayer];  [uiview animatewithduration:0.5 animations:^{      textlayer.foregroundcolor = finalcolor;    }]; 

it easier working calayer

let mylabel: uilabel!  uiview.animatewithduration(2, animations: { () -> void in      mylabel.backgroundcolor = uicolor.redcolor(); }) 

thats it...

edit

ok, sorry didn't knew color want change... have converted example swift code...

first

import quartzcore 

than

if let layer: calayer = self.view.layer calayer? {     if let textlayer = catextlayer() catextlayer? {         textlayer.string = "my string"         textlayer.foregroundcolor = uicolor.whitecolor().cgcolor         textlayer.frame = self.view.bounds         self.view.layer.addsublayer(textlayer)          uiview.animatewithduration(0.5, animations: { () -> void in             textlayer.foregroundcolor = uicolor.redcolor().cgcolor         })     } }
