cannot find initializer type 'uicolor' accepts argument list of type '(red: float, green: float, blue: float, alpha: float)'
wrong?

func pickerview(pickerview: uipickerview, didselectrow row: int, incomponent component: int) {      var newbackgroundcolor = uicolor()      var redcode: float = 0.0     var greencode: float = 0.0     var bluecode: float = 0.0     var alphacode: float = 0.0      if component == 0 {         switch row {         case 0..<256:             redcode = float(row/255)             newbackgroundcolor = uicolor(red: redcode, green: greencode, blue: bluecode, alpha: alphacode)         default:             break         }      } else if component == 1 {         switch row {         case 0..<256:             greencode = float(row/255)             newbackgroundcolor = uicolor(red: redcode, green: greencode, blue: bluecode, alpha: alphacode)         default:             break         }      } else if component == 2{         switch row {         case 0..<256:             bluecode = float(row/255)             newbackgroundcolor = uicolor(red: redcode, green: greencode, blue: bluecode, alpha: alphacode)         default:             break         }      } else {         switch row {         case 0..<256:             alphacode = float(row/255)             newbackgroundcolor = uicolor(red: redcode, green: greencode, blue: bluecode, alpha: alphacode)         default:             break         }      }      self.view.backgroundcolor = newbackgroundcolor }

use cgfloat not float

check api docs when error this
