ios - Custom variable 'layer' used before being initialized -


i create custom calayer set items corner radius.

func getlayercorner(radius:cgfloat) -> calayer {     let layer:calayer     layer.cornerradius = radius     layer.maskstobounds = true      return layer }

i'm getting variable 'layer' used before being initialized

i'm still learning swift , not sure how init it.

the error states wrong code. need initialise layer before using:

func getlayercorner(radius:cgfloat) -> calayer {     let layer           = calayer()     layer.cornerradius  = radius     layer.maskstobounds = true     return layer }
