114 NSViews to CALayers

115 Layer Backing No longer necessary to set.wantslayer = true AppKit handles this for you

116 Layer Backing class ColorLayer : CALayer { override func draw(in ctx: CGContext) { ctx.setfillcolor(nscolor.systemred.cgcolor) ctx.fill(cgrect.infinite) } } class ColorLayerDelegate : CALayerDelegate { func draw(_ layer: CALayer, in ctx: CGContext) { ctx.setfillcolor(nscolor.systemred.cgcolor) ctx.fill(cgrect.infinite) } }

117 Layer Backing class ColorView: NSView { override func draw(_ dirtyrect: NSRect) { NSColor.systemRed.set() dirtyrect.fill() } }

118 Layer Backing class ColorLayer : CALayer { override func display() { self.backgroundcolor = NSColor.systemRed.cgColor } } class ColorLayerDelegate : CALayerDelegate { func display(_ layer: CALayer) { layer.backgroundcolor = NSColor.systemRed.cgColor } }

119 Layer Backing class ColorView: NSView { override func draw(_ dirtyrect: NSRect) { NSColor.systemRed.set() dirtyrect.fill() } override func updatelayer() { self.layer?.backgroundcolor = NSColor.systemRed.cgColor } }
