Besides the documentation, the XignSys GmbH also provides access to the XignSDK Demo app with source code, which implements the SDK. The app is accessible via the XignSys GitLab from the following links: XignSDK Demo iOS and XignSDK Demo Android. The demo app is mainly used for internal development purposes and therefore comes with some constraints:
Also, the structure can and will change in future updates without notice as development progresses.
On the other hand, the official XignSys app Xign.Me can always be downloaded from the respective stores Xign.Me App Store and Xign.Me Google Play. In contrast to the demo app, Xign.Me implements the XignSys SDK to its full extend.
Important: It is highly recommended installing the Xign.Me app at least once and register a new account, activate the app and authenticate against the official XignIn-Manager https://xign.me to see the flow of the main processes of the SDK.
