Simplifying Backwards Compatibility in Swift
Every year as new OS and Swift versions are released, the question comes up over and over again: “how do I use this new thing while also supporting older versions?â€. While we have a bunch of “availability†tools at our disposal (and I’ll be using them in this post), they always come across as somewhat cumbersome: we need to do inline checks, or we have conditional logic flow that obfuscates the in

How to write unit tests for SwiftUI apps
unit and acceptance testing, automation, productivity How do you write unit tests for a SwiftUI application?
