How to initialize UIBezierPath to draw a circle in swift?

I'm trying to draw a circle in Swift, but when I write my code I get a error "could not find an overload for 'init' that accepts the supplied arguments.

In the class UIBezierPath there is a init function:

init(arcCenter center: CGPoint, radius: CGFloat, startAngle: CGFloat, endAngle: CGFloat, clockwise: Bool) -> UIBezierPath

But when I declared this with this code I get the error.. Need I cast any variable to other type? but if I compiled this in iphone 4 I don't get the error, only in iphone 5/5s. How can declare this correctly?

let arcCenter = CGPoint(x: CGRectGetMidX(self.bounds), y: CGRectGetMidY(self.bounds))
let radius = Float(min(CGRectGetMidX(self.bounds) - 1, CGRectGetMidY(self.bounds)-1))

let circlePath : UIBezierPath = UIBezierPath(arcCenter: arcCenter, radius: radius, startAngle: -rad(90), endAngle: rad(360-90), clockwise: true)



You need to convert values that are passed as arguments in UIBezierPath 's init method to CGFloat, because Swift sees them as Double or Float (let radius).

 let circlePath : UIBezierPath = UIBezierPath(arcCenter: arcCenter, radius: 
CGFloat(radius), startAngle: CGFloat(-rad(90)), endAngle: CGFloat(rad(360-90)), clockwise: true)
