  Example:
```
func testAddition() {
    let result = add(2, 3)
    XCTAssertEqual(result, 5, "Addition function failed")
}
```
Pro Tip:
Automate your tests using Xcode’s Continuous Integration (CI) feature to ensure code quality with every new change.

UI Testing
UI testing validates the user interface, ensuring buttons, labels, and other elements work as expected. Xcode lets you record interactions and turn them into repeatable tests.
Steps to Create a UI Test:
- Create a UI testing bundle similar to unit tests.
- Use the recording feature in Xcode to capture UI interactions.
Example:
Record a user navigating through your app and ensure all buttons trigger the correct actions.
