Technical

The app was created as a native iOS implementation of the Apollon Standalone web client. We employ the MVVM design pattern as the general architectural pattern. The main modeling functionality is imported from the Apollon-iOS-Module SPM package and utilizes the ApollonEdit module to enable users to create, modify, and interact with UML diagrams. The previews on the home screen utilize the ApollonView module to allow users to see a preview of their diagram. Further, the diagrams are saved locally on the device using SwiftData, so no internet connection is needed.
