Looking at the logo i expect Apple to announce their "Design Language/Guidelines" since the competition does already have their design system/guidelines: Microsoft with their "Fluent Design System" and Google with their "Material Design".
It's about time for Apple to follow that path which might give us early hints on the so rumored "Cross Platform Applications" a single app that works on iOS,macOS,watchOS,tvOS.
I Expect some Siri new skills (although it would take ludacris mode development to be at least on the trail of Google Assistant).
But overall my wishlist for WWDC2018 is:
MacOS
- FaceID like unlocking on macOS.
- New Apple apps added to the macOS: Health, Home, Wallet and Upgrades to existing ones.
- Some major new features on the platform for a better gaming experience, they are already the #1 gaming platform on iOS so i expect them to attempt to grab that area on the macOS too since its already not a good gaming platform, they might work towards that.
- a redesigned macOS (following their new design system).
- More eGPU support including Nvidia GPUs
iOS
- New design by following their Design system guidelines (if im correct on the WWDC logo).
- Revamped Notifications (or at least add grouped notifications/notification channels).
- Dark Mode
- Application Manager (Clear cache,Reset App)
- Enhanced Battery Manager (View more detailed informations per app usage etc).
- Unlocked Home Screen Arrangement (let them keep the grid but let us move icons from top to bottom or place them how we want).
- Improved Keyboard (add swipe typing, Custom Dictionaries, etc).
- Phone App = add call recording option.
