Swift Testing

Core testing patterns for Swift using the Swift Testing framework, XCTest, and XCUITest.

When to Activate

• Writing tests for Swift or SwiftUI code
• Setting up a test target in Xcode
• Testing async/actor code
• Writing UI automation tests
• Achieving 80%+ code coverage in Swift projects
• Migrating an existing XCTest suite to the Swift Testing framework (@Test, #expect)
• Debugging flaky tests caused by shared mutable state or fixed sleep waits
• Adding parameterized test cases to cover multiple input combinations efficiently
