Rotate UIView around its center keeping its size

Question

I\'m trying to rotate an UIView a few radians but after applying the transformation it doesn\'t look to be keeping its size. What\'s the proper way to achieve t

Update Luca Davanzo's answer with Swift 4:

/**
 Rotate a view by specified degrees

 - parameter angle: angle in degrees
 */
func rotate(angle: CGFloat) {
    let radians = angle / 180.0 * CGFloat.pi
    let rotation = self.transform.rotated(by: radians)
    self.transform = rotation
}
