Explanation:

1. CoreML is Apple's framework for machine learning on iOS. TensorFlow and PyTorch are more general - purpose ML frameworks not exclusive to iOS. UIKit is for building user interfaces, not ML.
2. XCTest is Apple's native testing framework for iOS unit testing. JUnit is for Java, PyTest for Python, and Mocha for JavaScript.
3. TestFlight is Apple's tool for beta - testing apps. Instruments is for performance analysis, Xcode Cloud is for continuous integration and delivery, and Core Data is for data persistence.

Answer:

1. B. CoreML
2. B. XCTest
3. A. TestFlight
