Create a detailed code implementation using the HealthKit framework in Swift (specify the version, e.g., Swift 5). The implementation should focus on tracking daily step counts and heart rate monitoring, suitable for an iOS app targeting iOS 15 and later. Include comments to explain the key parts of the code, and ensure it follows best practices for accessing and handling HealthKit data. If possible, provide a brief overview of the necessary permissions and a basic UI for displaying the tracked data.
