An App Group roller coaster ride

Read Original

The article describes a developer's experience debugging a random failure in data synchronization between a SwiftUI app and its keyboard extension using an App Group. The issue involved deep links, a DocumentGroup-based app structure, and was complicated by the app having multiple build configurations for different variants. The post explains the technical setup, the problem of a shared flag not being set reliably, and the investigation into the root cause.
