Let's investigate the iOS 8.2 beta 4 features that was released to developers just a day back. As an every new update that comes for developers it was launched with the usual bug fixes and such, there are some of other new and notable additions to the release. The main feature of this update is Apple Watch support, with a new addition shows that’ll eventually allow Apple Watch owners to connect their favorite iPhone with their wearable.
The WatchKit SDK has been already rolled out by Apple company, that is the huge enrichment of the new platform. And together with Apple Watch that will be on sale this spring, the groundwork is already underway to ensure that iPhones are ready to sync with the smartwatch right out of the box.
Certainly, fluidity is the thing which we’ve expected not only from iOS itself, but from the entire Apple ecosystem and product line. Concerning these early indications revealed in iOS 8.2 beta 4, it seems pairing devices with Apple Watch will be do in the simplest way.
Another one of iOS 8.2 beta 4 features is Bluetooth support for the Apple Watch, and references to a dedicated Apple Watch app.
Together with Bluetooth settings, there’s also now a menu dedicated to pairing with Apple Watch. And as Apple Watch is not yet out to the public, developers won’t be able to use this options. This new menu does introduced a snippet of process how everything will come together when it does.
Due to rumors the Apple Watch will only sync with iPhones when the dedicated companion app is installed on all devices. But there were nothing officially announced. But the Bluetooth settings panel also includes a command directing users "go to the Apple Watch app" if they wish to pair iPhone with Apple Watch.
So, it seems like it will certainly be an Apple Watch app and tweak the experience using their larger-screened iPhones
