New Apple Watch apps need to work without an iPhone

A new requirement for Apple Watch developers will be a boon for users. Apple sent out a notice that new apps for the Apple Watch will need to run natively on the smartwatch before it’s submitted to the App Store. This means the apps will work on the Watch itself without having its paired iPhone nearby. Previously, Watch apps were streamed from the iPhone, meaning you needed to have the phone with you at all times and apps were slow to launch and a bit sluggish. Having apps run natively on the smartwatch will result in quicker response time and the ability to run more smoothly.
Developers who want to submit starting June 1st will have to adhere to this. The apps will be built with the new watchOS 2 SDK because support for the 1.0 SDK and any apps built with that will be discontinued.
