"Core is unavailable" and "Match Faces API call failed" errors appear in the iOS application

Issue:

When integrating the Face SDK into the iOS app, the following problems occurred:

1. The SDK failed to initialize, displaying the error message: Core is unavailable.
2. Despite setting up a custom web service and specifying the serviceUrl in the configuration, the error Match Faces API call failed was received.

Solution:

These problems are likely caused by incorrect integration of the Core component into the project. The Core component is essential for Face SDK functionality and must be correctly integrated.

To resolve these issues, please follow these steps:

1. Verify Core Integration. Ensure the Core component (either Core Basic or Core Match) is selected and connected as described in the installation documentation.
2. Check for License Conflicts. If a license is included in the project, the SDK may prioritize offline processing using the local Core, potentially leading to conflicts. To prevent this, remove the license from the project and add Core Match instead.
