UIView Rotaton

Extensions.swift

extension UIView {
    func rotateRad(r: CGFloat) {
        self.transform = CGAffineTransformMakeRotation(r)
    }
    
    func rotateDeg(r: CGFloat) {
        self.transform = CGAffineTransformMakeRotation(r.degreesToRadians)
    }
}

// Include degrees to radians extension


// Usage 
self.box.rotateRad(CGFloat(M_PI))
// or 
self.box.rotateDeg(45)
