What is your experience with iOS testing?

In iOS testing, I have experience with both manual and automated testing. I used XCTest to write unit tests and UI tests, verifying the correctness of the interface and business logic. I am also familiar with using XCUITest for automating user scenarios. For integration testing, I employed mock services and device simulators. I paid special attention to testing on different iOS versions and various device models to ensure the stability and performance of the application.
