As of March 20, 2023, deleting an app’s auto-generated free provisioning profile is no longer supported. However, fetching the provisioning profile now re-generates is every time, so there’s no need to delete it first.
As a workaround, we now simply use the first profile we fetched if we receive an error when deleting it. This approach should continue to work even if Apple later reverses this change.
Apparently changing NSLayoutConstraint priorities from required to optional (and vice versa) isn’t supported, even though it works on iOS 13+. Who knew!
The MacDirtyCow exploit allows users to remove the 3 active apps limit on iOS 16.1.2 and earlier. To support this, we’ve added a new (hidden) “Enforce 3-App Limit” setting that can be disabled to allow sideloading more than 3 apps.
In addition to removing the app extensions themselves, we also need to remove references to them from SC_Info/Manifest.plist in the app bundle (if the file exists). Otherwise, subsequent installations (resigning, (de)-activating, etc.) will fail due to “missing” app extensions.
AltStore assumes all apps have unique bundle IDs per source. Weird bugs can occur when this is not the case (such as merging multiple store listings into one), so we now verify upfront whether source contains duplicate bundle IDs before saving.
Unlike MyAppsViewController, AppViewController will attempt to update to the latest available version, rather than the latest supported version. If the latest version is not supported, it will fall back to asking user to install last supported version.
When unsupported updates are available, the “No Updates Available” text becomes “Unsupported Updates Available”, and a button is revealed that will list all unsupported updates in an alert when tapped.
This allows us to use @Managed with properties that may or may not be NSManagedObjects at runtime (e.g. protocols). If they are, Managed will keep strong reference to context like before.
We now store the latest supported version as a relationship on StoreApp, rather than the latest available version. This allows us to reference the latest supported version in predicates and sort descriptors.
However, we kept the underlying Core Data property name the same to avoid extra migration.
