Auto Layout offers a constraint-based design approach that allows iOS developers to create user interfaces for multiple devices. If you’re using Swift Playgrounds or need portable and modular code, programmatic Auto Layout is your prime choice. In this course, instructor Steven Lipton talks about the different options you have to create constraints programmatically in Swift—and how to use each one. He also shows how to use size classes, stack views, and priorities for the fastest, most adaptable UI on any iOS device.
Topics include:
- When and why to use Auto Layout programmatically
- Creating constraints in Swift
- Resolving errors in Auto Layout
- Using the safe area
- Working with the Visual Format Language
- Adding a stack view
- Harnessing the power of inequalities and priorities in constraints
- Understanding traits and size classes
