Just after releasing AppCode 2022.3 JetBrains announced end of life for this product. AppCode is no longer sold and JetBrains will provide support for existing customers until December 31, 2023.
Developers are encouraged to migrate to other development environments.
Until December 31, 2023, we will continue to provide technical support and release updates that specifically address compatibility issues with Xcode 14, as well as critical security updates as necessary. The scope of the updates will be limited to these two areas.
