Device identification using a vendor keychain

By storing device IDs in the app's keychain, you can uniquely identify a device for custom reports in AppMetrica. However, if a device has multiple apps from the same developer installed, the device might be identified differently in the reports for each of the apps. To avoid this issue, use a vendor keychain.

Setting up a vendor keychain

1. In the Xcode interface, go to the Capabilities section and enable Keychain Sharing.
2. In the Keychain Groups field, add the group io.appmetrica.

After you have set this up, the AppMetrica SDK automatically uses the vendor keychain data.
