https://developer.apple.com/videos/play/wwdc2018/209/

• NSImage(named: string) is now allowed!

• NSMenuItemValidation is now a real protocol, other informals have been made real

• Secure coding with NSKeyedArchiver, unarchiver

• NSColor.controlAccentColor

• .withSystemEffect - pressed, disabled, etc.

• Content Tint Color

• NSButton, NSImageView contentTintColor

Layer Backing

• Not one to one NSView to CALayer (unlike UIKit)
• No need to set .wantsLayer = true
• Use NSView draw method instead of layer drawing
• Fine to implement updateLayer along with draw method
• .wantsUpdateLayer is okay
• Don’t use NSView lock/unlock focus

User Notifications

• NSUserNotification deprecated

NSToolbar

• centeredItemIdentifier
• Auto layout now used when min max sizes not specified

NSGridView

• Grid views authored in IB work in 10.13

NSTextView

• fieldEditor
• scrollableTextView
• etc.
• performValidatedReplacement - calls delegates properly, fills in atts from typing atts
• May need to call setSelectedRange first to get proper atts
• validRequestor - Services API
