Apple has launched iOS 13 and watchOS 6, as well as — to a limited degree — its Apple Arcade gaming service.
You can download iOS 13 on your iPhone by going to General > Software Updates. Apparently, the iPadOS 13, as well as macOS Catalina and HomePod software updates, aren’t arriving until next month.
watchOS 6 can be downloaded for free through the dedicated Apple Watch app on the iPhone by going to General -> Software Update. To install the new software, the Apple Watch needs to have at least 50 percent battery, it needs to be placed on a charger, and it needs to be in range of the iPhone.
You can access Apple Arcade through the App Store on your iPhone using the new Apple Arcade tab in the navigation bar. As for the Mac and iPad, it’s still “coming soon.”
