Native SDK for Developers:
Expect your Apple Watch apps to run much faster, smoother, and more reliably starting this fall. Apple is planning to release its first beta of the native Apple Watch SDK to developers at WWDC. These native tools will allow Apple Watch developers to make Watch apps that install directly onto the Apple Watch and can utilize sensors, the Digital Crown, and the processing power of the wearable. Currently, WatchKit apps run on your iPhone and transfer data to your Watch over Bluetooth.
Future Software Upgrades:
While Apple may not choose to use the WWDC stage to debut software upgrades to Watch OS, we have learned that Apple is preparing a Watch OS update to match iOS 9 that is internally called Bondi. While we do not have specifics on what is in store for that iOS 9 upgrade, weve reported that Apple is working on third-party watch face Complication support, improvements to the heart rate reader functionality, Smart Leashing, a Find my Watch feature, and more.
Untethered Hardware:
Besides talk of new Apple Watch software, we have heard that Apple is making headway on the development of the 2016 Apple Watch hardware and software updates. We are told that one of the top priorities within the Apple Watch development labs is to make the device independent of the iPhone, essentially untethering it. This doesnt mean your next Apple Watch will work with Android, but it means that your Watch will be able to do far more over WiFi and Bluetooth than it can today.
