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
