There is a lot of talk around WWDC. Apple will introduce HealthBook, home automation SDKs, a flat UI for OS X, etc.
Here is what I am hoping for:
Development
* Xcode 6 that doesn’t crash when compiling XIBs via the command line
* Xcode 6 with better refactoring and editing tools (AppCodeque)
* Xcode 6 with a better IB that allows for shared resources such as named colors across XIBs
* Ability to ship alpha/beta versions of our in-production apps to opt-in/select customers via the App Store
* App distribution (Testflight) built into Xcode
* Better Xcode CI functionality around externally hosted GIT repositories that use submodules
* UIKit on OS X
* A better Feedback tool for submitting/tracking/communicating about radars
* Elimination of useless Team Provisioning Profiles
* A “fix” button in Xcode that does not break more than it fixes
iOS
* Better keyboard (or even custom keyboards)
* AirDrop to OS X
* 100% Calendar parity (edit/create every type of event, such as M W F)
* Better battery life
* Better GPS accuracy when in Airplane mode
* Widgets on homescreen
* Siri that allows me to retry a command when one fails
* Built in transit
