Lesson in the iOS Roadmap · Stage 9: SwiftUI

What is Breakpoints?

Breakpoints pause app execution at a specific line of code so the developer can inspect the current state of variables and the call stack. Xcode supports line breakpoints, symbolic breakpoints that trigger on a function name, and exception breakpoints that catch crashes automatically. Conditional breakpoints pause only when a specified expression evaluates to true.
