Native features

Included at launch: push and local notifications with badges, haptics, the share sheet, opening outside links in Safari, deep links, a tab bar, the review prompt, pull to refresh, an offline screen, clipboard, device info, network status and native alerts.

Coming later as paid add-on packs: camera, photo library, files, barcode scanner, location, Apple Maps, Face ID lock, secure storage, screen brightness and home screen quick actions. They show in the design screen as "coming as an add-on" and can't be switched on yet.

Apple rejects apps that only repackage a website (guideline 4.2). Turning on native features such as push notifications and a tab bar helps your app pass review.
