At events like the WWDC keynote from earlier this month, Apple is fond of throwing up a slide touting how many new features a product has. At WWDC, we saw that iOS 6 has 200 new features. But the event itself is limited and not all of those features can be listed and even fewer can be talked about in the keynote itself. We took the list presented at the keynote and listed the ones not talked about and present a hefty does of informed speculation about what the new features mean.
Game Center Features
Game Groups - This one is really unknown right now. But I read one thing into it, gaming clans. At least that's what I hope it is. The ability to create Game Center based clans, that can persist between games, would be fantastic.
Game Center Friends from Facebook - You can find Game Center friends from your Facebook friends. When a Game Center user signs up their Facebook account in iOS 6, it links their Game Center account allowing you to find each other.
Game Center Challenges - When you hit a high score, it will now be easier to challenge your friends to beat that score.
Game Center in-app experience - More of Game Center will be exposed directly in the game, no need to go to the Game Center app to perform some functions.
New Maps App
Transit Apps - How this will function is unknown. Apple chose to leave out transit info in their new Maps app and instead look to third party app developers to provide that feature. To what extent that data will be present in the Maps app is a big unknown. At the keynote it was mentioned that Apple would "integrate, promote, and feature" transit apps within the Maps app.
Map Kit - this is the API that developer use to integrate the new Maps into their applications.
Lots of interesting changes to the Camera APIs should allow for even greater manual control of the camera from third-party apps.
Control Camera Focus and Exposure - The ability to control the focus and exposure without just point to spots on the screen will go a long way to giving developers the ability to provide full manual controls in their camera apps.
Video Stabilization - Video stabilization was only available in the built-in Camera app. It will now be available to third party apps.
Face Detection API - The face detection feature used in the Camera app will now be available in third party apps as well. Might make for some interesting app usage even outside camera apps.
Read and write image metadata - The metadata of an image contain things like when and where the image was taken and loads of info on what settings were used to capture the image. It also contains info on the photographer and copyright. This new API for developers will allow them to read that metadata and write it back out much more quickly.
HDR Improvements - The HDR mode is an interesting and misunderstood mode in the camera. Any improvements are greatly anticipated.
