Bardi Golriz did a great job of gathering all questions and answers on SwiftUI from WWDC23 Digital Lounge.

• WWDC23 #SwiftUI
• WWDC 23 was our favourite ever yet

WWDC23 week is over, all announcements are already made, Apple and developers are going through highlights of the conference.

Apple lists important sessions on spatial computing, developer tools, Swift, UI frameworks, design, graphics and games, ML, privacy and security, and other topics.

Apple also asks developers to take part in survey that could shape the future of conference.

macOS 14 Sonoma

Developers highlight FaceTime reactions, presenter mode for screen sharing and various of other features.

Widgets availability for macOS should help bringing more apps to Mac from iPhone and iPad.

Another area of interest is support for web apps.

tvOS 17

Apple TV is to support VPN apps with tvOS 17. This will put tvOS on par with other Apple platforms.

Also, tvOS will improve sound for dialogs to make voice more audible. This feature requires second generation HomePod (original HomePod and HomePod mini are not supported) and Apple TV 4K.

iOS/iPadOS 17

DockKit SDK and Standby mode bring interesting capabilities for apps and also could hint on more standalone home devices.

Autocorrect in standard keyboard is expected to become much better with iOS 17.

iCloud

iCloud Drive now could be switched off and third-party apps will still be able to sync via iCloud.

Vision Pro

Analysts expect that more affordable version of Vision Pro will be released in 2025.

M2 Ultra

Benchmarks for M2 Ultra show significant improvements over M1 Ultra chips. New chip is 20% faster than previous generation.

No details are provided by Apple on actual hardware specifications of Vision Pro so far. Some information is gathered through WWDC sessions, interviews, responses.

Sensors

Apple announced 12 cameras, 5 sensors on the headset. LiDAR, and 3D imaging cameras are installed. Apple mentioned that only some of these cameras and sensors will be available for developers, while others will be used for face scanning and gesture recognition. Four cameras with LED illumnatio will be tracking eye movements.

Physical controls

Headset features Digital Crown (which also acts as a button) and separate button which could trigger photo capture or video recording. No controllers are required to work with Vision Pro. There are multiple "standard" hand gestures which are detected by the system and custom gestures could be implemented by application developers.

Gestures

Notably, Vision Pro support direct touch manipulation and "indirect" subtle finger gestures like pinches. Eye glance is used to highlight element which will be responding to gesture.

Graphics

Internal displays are made using micro-OLED technology and have total of 23 million pixels. It is reported that Vision Pro runs on 90Hz refresh rate with boosts to 96 Hz to display 24 FPS video content properly.

Chips

Vision Pro is powered by M2 and R1 chips. M2 acts as CPU/GPU engine for the headset while R1 is focused on signal processing to accumulate and analyze information coming from cameras and sensors.

Power

Headset could be used plugged in or via external battery. Vision Pro should have 2h battery life.
