Legacy Constant Violation for CGFloat(M_PI) * 2

For the following:

struct Constants {
    static let m2Pi = CGFloat(M_PI) * 2
}

SwiftLint 0.16.1 is warning me:

warning: Legacy Constant Violation: Struct-scoped constants are preferred over legacy global constants. (legacy_constant)

Note that I need this value for UIBezierPath.init(arcCenter center: CGPoint, radius: CGFloat, startAngle: CGFloat, endAngle: CGFloat, clockwise: Bool) to get a closed arc.

In swift 3, pi is now defined this way:

CGFloat.pi

You can also get it this way:

Double.pi 
Float.pi
