Sometimes Apple showed new hardware at WWDC, such as updated Macs, and if you believe the rumors, we'll only see software for the WWDC in 2018.
On iOS 12, Apple will focus on bug fixes and enhancements to existing features to avoid some of the issues that iOS 11 has seen over the year. Actually, Apple had originally planned to introduce a number of new features, such as improving the splash screen with a redesigned app grid, and incorporating a redesigned CarPlay interface as well as enhancements to core applications such as mail and new features for camera and photo applications. But according to a report by Bloomberg, these functions were repealed for iOS 13.
Completely without innovations but iOS 12 will not get along. Rumor has it that Apple is planning some kind of cross-platform functionality with macOS, which will allow developers to build a single application that works on iPhones, iPads and Macs, which would successfully increase the number of Mac applications available for download. At the moment the two worlds are almost completely separated.
Apple will also integrate new Animoji on the iPhone X and enable Face ID in horizontal mode as well. This would be important for the iPad Pro model if they are equipped with Face ID.
There may also be an Animoji integration in FaceTime so that the animated Emoji characters can be used in a video call.
It also aims to bring new digital health tools that help users better monitor how much time they have spent on their iPhone and iPad. These tools will also be available to parents to monitor the use of their children's devices. This is intended to alleviate concerns about smartphone addiction.
ARKit 2.0 should focus on multiplayer gameplay so that two players can see the same virtual objects. In addition, virtual objects that were placed in an augmented reality app should still be available after a session. For example, you could hang a virtual image on the wall with an app, and when you open it again, the image will still be there.
With iOS 12, Apple aims to make the iPhone's NFC capabilities simple on the go Expanding payment and allowing users to safely open doors with NFC technology.
In addition, there will be a new stock app and a deeper Siri integration in photos for search purposes. There are also changes to the iBooks app.
macOS 10.14 may support cross-platform applications, so applications developed for iOS can run on the Mac as well.
Apart from that there is hardly any information, what to expect with macOS 10.14. Apple may be planning a redesign of the Mac App Store. We expect the new Apple file system APFS for Fusion Drives will come.
tvOS 12, watchOS 5 and new HomePod Software
Apple will certainly provide information for tvOS 12 and watchOS 5, but there is still no information or rumors whatsoever about what these operating systems can do become. Of course, watchOS introduces a new dial, but that's hardly worth mentioning.
