This version is compatible with iOS 7.0 to 13.3.1 and partially compatible with iOS 14.0 to 14.8.1. The current version of CesiumHelper works just fine on iOS 14.0 to 14.8.1, but with a cosmetic issue where the Control Center will still continue to show the Music app. Tapping on the Control Center music app icon will still launch Cesium as expected.

CesiumHelper greatly enhances the Cesium music player's integration with iOS by opening the Cesium music player whenever the Music app would normally be opened (for instance, tapping on the Now Playing widget in the Control Center).

In other words, this allows you to finally use Cesium as a full replacement for the default iOS Music app!
