contentAspectRatio
The window’s content aspect ratio.
Declaration
var contentAspectRatio: NSSize { get set }Discussion
By default, the content aspect ratio (that is, height in relation to width) is (0, 0). If you set the aspect ratio of a window’s content view, the dimensions of its content rectangle are constrained to integral multiples of that ratio when users resize it. You can set a window’s content view to any size programmatically, regardless of its aspect ratio. The value of this property takes precedence over aspectRatio.
