Set NSWindow Size programmatically

Question

How can I set the window size programmatically? I have a window in IB and I want to set the size of it in my code to make it larger.

Answer 1

Usually I want to resize the window based on the size of the content (not including the title bar):

var rect = window.contentRect(forFrameRect: window.frame)
rect.size = myKnownContentSize
let frame = window.frameRect(forContentRect: rect)
window.setFrame(frame, display: true, animate: true)
