In this talk from Swift Heroes 2025, Muralidharan Kathiresan breaks down everything you need to know about Apple’s new testing framework: SwiftTesting. Whether you're a seasoned iOS dev or an indie developer looking to speed up your release cycle, this session covers it all—unit testing basics, how SwiftTesting compares to XCTest, its powerful new traits like @Test, #expect, #require, and how it integrates with tools like Xcode Cloud. You’ll even see a live demo showing how to migrate your existing test suite. Learn when to use async/await, closures, or Combine—and how SwiftTesting can truly level up your QA process. A must-watch if you care about stable, testable, and high-quality code!
