watchOS 2 new API and Sample Code

Question

Is there any good link explaining about watchOS 2 new features and API?

I have tried few of the API, but I want to explore more.

Thank you

Answer 1

You can find a lot of information in Apple developer portal. There are release notes, videos, guides, etc which you can access them by visiting this website:

https://developer.apple.com/watchos/pre-release/

WWDC15 videos may help you a lot in order to find info about watchOS 2. Visit this website for videos:

https://developer.apple.com/videos/wwdc/2015/

There are a lot of videos about watchOS 2, including Introducing WatchKit for watchOS 2 and a lot other videos.

Answer 2

Apple has excellent documentation and sample code available. Always start there first, but here are some initial thoughts from another excellent resource: http://www.raywenderlich.com/108415/watchkit-for-watchos-2

Answer 3

WWDC15 videos or Apple's documents are exactly helpful, however there are few buildable sample codes for the new features. Even the Apple's sample code, they are not enough (for example, WatchKit Catalog doesn't include examples of new UI components such as WKInterfacePicker so far).

So I created a open source repository which is a collection of sample codes for new features of watchOS 2.

• Accelerometer
