The document presents an overview of WatchKit, Apple's framework for developing applications for the Apple Watch, detailing its integration with iOS apps and outlining the app life cycle and structure. It discusses interaction techniques, UI controls, navigation methods, and data passing between interface controllers, along with limitations such as a lack of multi-touch support and sensor access. It also includes configuration steps for integrating WatchKit into Xcode and provides references for further learning.

3. Overview of WatchKit App

WatchKit is an Apple's new framework to create applications for apple
watch.

WatchKit apps are not standalone apps, means these apps need
to be paired with iOS App.

Watch App will be an extension of iPhone Apps. The iPhone app is
responsible for installing and running watch app.

4. Apple Watch Models
Apple has introduced apple watch with two different size, both having
retina display.

38mm screen with 272*340 px resolution


5. Interaction with Apple Watch

Gesture

Force Touch (holding or tapping the screen for few seconds, menu
screen will be displayed)

Digital Crown

Side button

6. Configure Apple Watch into Xcode
Steps to add watch kit app target into iOS App :-

In xcode, create a new project for iOS App

Select File>New>Target>Apple Watch Section

Select WatchKit App then click next

Click Finish

7. App Target Structure

8. Build and Run Process
Steps to configure custom build schemes for glance and notification :-

Select existing watch kit app scheme

Now select Edit Scheme

Duplicate existing watch app scheme

Select Run in the left column of scheme editor

In Info Tab, select watch interface

Close the scheme editor to save your changes

9. Watch Kit App Life Cycle

10. Life Cycle of Interface Controller

11. Methods of Interface Controller

init

awakeWithContext:

willActivate

didActivate

12. Apple Watch UI Component
Apple watch provides 3 different ways to create the UI :-

WatchKit Apps

Glances

Notifications

13. Apple Watch UI Controls

Text and Labels

Button

Images

Tables

Context Menus

Groups

Date

NSTimer

14. Apple Watch Navigation

Hierarchical Interface
- pushControllerWithName:context
- popController
- popToRootController

Page-Based Interface
+ reloadRootControllersWithNames:contexts:
- becomeCurrentPage

Present Interface Controller Modally
- presentControllerWithName:context:
- presentControllerWithNames:contexts:
- dismissController

15. Passing Data between Interface Controllers

By pushing view controller programmatically :-
self.pushControllerWithName("PushData", context: "Data Received by
pushing interface controller")

By creating segues :-
override func contextForSegueWithIdentifier(segueIdentifier: String) ->
AnyObject?
{
return "Data Received from Segue"
}

16. Demo of layout implementation
using Groups, button and images, table and
menus

17. Limitations of Apple Watch

Multi-touch is not supported.

No access to the sensors on the Apple Watch.

Watch App has 20MB image cache, limit cannot be changed.
