Deactivating apps by removing their profiles no longer works on iOS 13.5. Instead, AltStore will now back up the app by temporarily replacing it with AltBackup, then remove the app from the phone.
iOS 13.3.1 limits free developer accounts to 3 apps and app extensions. As a workaround, we now allow up to 3 “active” apps (apps with installed provisioning profiles), as well as additional “inactivate” apps which don’t have any profiles installed, causing them to not count towards the total. Inactive apps cannot be opened until they are activated.
Assuming the certificate used to originally sign an app is still valid, we can refresh an app simply by installing new provisioning profiles. However, if the signing certificate is no longer valid, we fall back to the old method of resigning + reinstalling.
AltStore now inserts an app-specific UTI when resigning apps, and it periodically checks whether that app has been deleted by checking whether UTTypeCopyDeclaration returns nil for the same app-specific UTI.
Tries to refresh apps that are about to expire first, and then always refreshes AltStore itself last, since refreshing AltStore means that the app will quit.
