Oh man! SwiftUI! It's gonna be great! Wait, what's that?
Tools for SwiftUI development are only available when running on macOS 10.15 beta.
Well, what are you going to do? Let's try playgrounds!
- ✅ Lesson 1: Creating and Combining Views
- ✅ Lesson 2: Building Lists and Navigation
- ❌ Lesson 3: Handling User Input
- ❌ Lesson 4: Drawing Paths and Shapes
- ❌ Lesson 5: Animating Views and Transitions
- ❌ Lesson 6: Composing Complex Interfaces
- ❌ Lesson 7: Working with UI Controls
- ❌ Lesson 8: Interfacing with UIKit
Ultimately, I had to give up. It got to the point where it was a worse experience compared to just Build & Running in Xcode. Why?
- Source files outside of the Playground wouldn't autocomplete which is crucial for something not well known or documented
- Source files weren't able to pull in code from the main Playground file resulting in an all-or-nothing approach to the code either being in the main Playground or in source files. This defeated the idea I was going for where the playground would be strictly the SwiftUI code which would live update
- I ran into technical issues associated with Playgrounds like
CGGraphicContextbeing grumpy, not being able to use .jpgs, and many others - Crashing, crashing, crashing.
I bought a USB thumb drive of decent speed and installed Catalina on that. It works fine.
