NHS COVID-19 AG

An app using Apple’s ExposureNotification API to detect contacts with other users of the app that may have had COVID-19.

Dependencies

All dependencies are fetched using Swift Package Manager. Make sure you have access to the internal dependencies, and that git is properly configured to access these.

Development

Running the app on a simulator

The app requires Xcode 13.2+. You don't need to install anything else. Swift Package Manager will fetch dependencies when you open the project.

Running the app on a device

This app requires entitlements that Xcode can not set up automatically. In order to run on a device:

• Ensure you are logged into the correct development team in Xcode.
• Ensure you have a development certificate and that your device is registered. Talk to a member of the team to learn about the latest policy around adding devices.
• Ask one of the technical App Managers to regenerate the provisioning profiles so it includes your device.
• Ask Xcode to download the latest profiles (Preferences > Accounts > Download Manual Profiles).

You should then be able to build and run on a device.
