Today Apple made developers aware that they can now create bundles for Mac Apps. Beginning with iOS 8 developers could create bundles of their iOS apps. You can bundle up to 10 iOS apps into a single bundle. Bundled Apps are now available for Mac Apps.
Mac App Bundles can also include 10 apps into a single bundle. The apps in the bundle can be either paid apps or free apps with auto-renewable subscriptions. App Bundles cannot combine both iOS and Mac Apps, they must all be apps for the same platform.
It is possible that iOS apps and macOS Apps may be bundled together in the future, but we will have to wait until Apple announces that to become a reality.
