What’s New in Cocoa - WWDC 2018

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

Custom Quick Actions
