Rotate

Rotate

You can rotate a view by creating a Transform and setting it to the view’s property:

view.transform = Transform.makeRotation()

Rotating a Transform will adjust itself between -M_PI and M_PI, if you need to accumulate or set rotations higher than +/- PI you can use the .rotation property.

Example

let r = Rectangle(frame: Rect(0, 0, 200, 200))
r.lineWidth = 15.0
r.center = canvas.center

let rotate = Transform.makeRotation(M_PI_4)
r.transform = rotate

canvas.add(r)
