I find this termination behavior too aggressive, and rewriting code to restore the previous state requires additional time and testing. Some apps remain visible in the App Overview but restart completely after being reopened. That’s not good user experience and feels unlike Apple’s usual standards, which seem to be declining in this regard. On a Mac or other computers, multiple apps can stay open without being restarted. iPhones have plenty of storage to save an app’s background data to disk instead of relying solely on RAM.

I think your app has at first to enter the background, so scheduleAppRefresh is executed. Then there is no error message.

hi i solved it by adding MonoInterpreter (set ☑️ checkbox) and Link only Frameworks in iOS-Build Settings
