bodyWithEdgeLoopFromPath: circle in swift

im having some trouble with the bodyWithEdgeLoopFromPath: method in swift. i want to make a simple circle that acts as a border. I found this http://www.raywenderlich.com/forums/viewtopic.php?f=2&t=10798 but its obj-c. any ideas ?

i also tried this piece of code

var path = CGPathCreateMutable();
CGPathAddArc(path, nil, 0, 0, 45, 0, M_PI*2, true);
CGPathCloseSubpath(path);

but i get the error 'init' is not convertible to 'CGFloat'

thanks!

The function you are using takes CGFloats, so make sure you are passing those in. You can create CGFloats using CGFloat(), which can take a numeric literal and some numeric types.

var path = CGPathCreateMutable();
CGPathAddArc(path, nil, CGFloat(0), CGFloat(0), CGFloat(45), CGFloat(0), CGFloat(M_PI*2), true);
CGPathCloseSubpath(path);

A look at the function definition shows which arguments need to be CGFloats. 

func CGPathAddArc(path: CGMutablePath!, m: UnsafePointer<CGAffineTransform>, x: CGFloat, y: CGFloat, radius: CGFloat, startAngle: CGFloat, endAngle: CGFloat, clockwise: Bool)
