Adding New Device Support

When Apple releases new devices, SDVersion needs to be updated. Here's how:

Finding Device Identifiers

Device identifiers (machine IDs) can be found from these sources:

Adding a New iPhone/iPad

  1. Update SDiOSVersion.h:

    • Add a new enum value in the appropriate year section
    • Use the next available integer value in that section

  2. Update SDiOSVersion.m:

    • Add the device identifier mapping in deviceNamesByCode
    • Add the display name in deviceNameForVersion:

  3. Update screen size detection if needed:

    • If the device has a new screen resolution, update resolutionSize

Adding a New Apple Watch

  1. Update SDwatchOSVersion.h:

    • Add enum values for each size variant

  2. Update SDwatchOSVersion.m:

    • Add identifier mappings
    • Update display names
    • Update screen size detection if new sizes are introduced

Adding a New Mac

  1. Update SDMacVersion.h:

    • Add new ChipType if applicable (M5, etc.)

  2. Update SDMacVersion.m:

    • Add model detection in deviceInformationForModel:
    • Map to appropriate device version and chip type

Code Style

  • Follow existing Objective-C conventions in the codebase
  • Use 4-space indentation
  • Keep device mappings alphabetically organized by identifier
  • Group devices by year in comments

Testing

Before submitting a PR:

  1. Ensure the project builds on all platforms (iOS, macOS, watchOS, tvOS)
  2. Test with the simulator for new devices if available
  3. Run pod lib lint to validate the podspec

Pull Request Process

  1. Fork the repository
  2. Create a feature branch (git checkout -b feature/add-iphone-17)
  3. Commit your changes with clear messages
  4. Update the CHANGELOG.md
  5. Submit a pull request
