📒 Field Notes

This day resolves around recapping the content covered while going through Projects 4-6 in Hacking with Swift. I won't try to rehash what I wrote up already, but a few additional tidbits are noteworthy:

• Whenever we're creating views in code — instead of with storyboards — overriding our view controller's loadView function is often the place to do it. For that matter, it's worth knowing about UIViewController's view loading lifecycle as a whole:

  • loadView
  • viewDidLoad
  • viewWillAppear
  • viewDidAppear
  • viewWillDisappear
  • viewDidDisappear
  • viewWillLayoutSubviews
  • viewDidLayoutSubviews

  The UIViewController docs have more on all of these — as well as this handy graph:

  

• Auto Layout in code:

  • VFL is cool
  • Anchors are cool — and usually a lot more useful.
  • UIStackView is another important part of this paradigm — but also a much larger topic 🙂.
