Necessary to support switching between AltStore beta and public version.
Wraps private non-optional _usageDescription value in public accessor with optional return type to still treat it as “optional” value.
Before, appPermissions was one array containing all permissions of different types.
Now, we split entitlement and privacy permissions into separate “entitlements” and “privacy” child arrays.
Before, whether or not the source included the buildVersion affected the comparison. If present, the buildVersion was used in comparison, if not, only the version itself was used for comparsion.
This meant it was impossible to update from a version with a buildVersion to the same version without one (e.g. going from betas to final releases). Now we _always_ consider the buildVersion in the comparsion, so an earlier entry in versions array without buildVersion can be considered “newer” even if versions match.
AltStore will now consider an update available if either:
* The source’s marketing version doesn’t match installed app’s version
* The source declares a build version AND it doesn’t match the install app’s build version
The installed app matches an app version if both maketing versions match, and the build versions match (if provided by the source).
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.
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.
Previously, AltStore would quit all other processes when first accessing the database no matter what. However, this unintentionally caused the widget extension to quit the main app after refreshing apps.
Now, we only quit other AltStore processes if a database migration is required. This still prevents multiple AltStores with different database schemas from accessing database concurrently, but also allows extensions to access database without quitting main app.
AltStore now sends a “WillAccessDatabase” notification before loading the persistent store, which causes other AltStore instances in memory to exit (either immediately, or upon returning to foreground).
This prevents multiple AltStore instances from simultaneously accessing the same database, which could result in corrupted data (especially if they used different database model versions).
We now set AppVersion.sourceID during migration, which fixes AppVersion entries conflicting across different Sources if multiple contain the same app + version.
Rather than store both the current user’s Patreon account and all cached Friend Zone patrons in the same table, we now store Friend Zone patrons in the new ManagedPatron table. This avoids the need to distinguish between the two at runtime.
