Learn Modern Auto Layout For iOS
Using Auto Layout? How many of these do you recognize?
⚠️ Randomly adding and removing constraints to get the layout you want
⚠️ Changing content hugging and compression priorities but not sure why?
⚠️ Conflicting constraints and a wall of debug text dumped to the console?
⚠️ Got a layout working on the iPhone but it looks terrible on the iPad and breaks on that tiny iPhone SE screen
⚠️ You want to add dynamic type for your users but there's no way that super-gigantic text size is going to fit
Add a constraint – Change a priority – See what happens…
You can try to work logically. But… Honestly adding constraints still feels like guesswork. Where do you start? When is it done?
Auto Layout is just too magical for your liking
Want to Auto Layout like a pro? Build flexible layouts that work everywhere? But feel like… you’re going in circles.
Learn to ❤️ Auto Layout
What if you knew how to approach a layout with confidence. You knew which constraints to add. When to squeeze a view and when to stretch it. You Know When You’re Done.
You’re cool with storyboards and relaxed about building layouts in code.
Let’s also make your layout adapt to dynamic type, different devices, and screen sizes.
It’s true that learning Auto Layout can make your head spin. But it doesn’t have to be that way…
Let me teach you modern Auto Layout...
The Key Principles You Need to Know
We start with topics often ignored. Learn how the view layout system works. The fundamental principles that turn Auto Layout into something predictable you can understand.
Learn what constraints you need to fully size and position a view. How to create them. Where to add them. How many you need.
Create Constraints The Easy Way
Auto Layout has changed a lot. Learn Modern Auto Layout with layout anchors and guides, stack views, safe areas, and size classes. Flexible layouts. Less work. Less boilerplate.
(No you don’t need to learn the Visual Format Language)
Take Your Pick - Code Or Interface Builder
Learn to create layouts in Interface Builder and programmatically. Use what works for you but know how to switch when you have to.
Learn By Doing
Practice makes perfect. Sharpen your Auto Layout skills with challenges that get you solving common layouts. Hints And Tips when you need them. Compare with my solution when you’re done.
Your Users Will Thank-You
Go the extra mile. Support dynamic type. Use layout variations, scrolling, and self-sizing table view cells. Create layouts that work from the smallest iPhone to the largest iPad.
