"SwiftUI is accessible by default" is one of the most repeated misconceptions in iOS development. Here’s why that’s wrong and what you actually need to watch out for.

Use the Xcode Build Optimization Agent Skill to analyze and improve your build times, saving hours per month.

In simple setups — a view behind an if condition, a sheet, a fullscreen cover — onAppear works exactly how you’d expect. Show the view, onAppear fires. Remove it, onDisappear fires. State is gone. Clean ... <a title="SwiftUI View Lifecycle: When onAppear…
