CHAPTER 1
INTRODUCTION
Apple Watch is a smart watch created by Apple Inc. and announced by Tim Cook on
September 9, 2014. The Apple Watch incorporates fitness tracking and health-oriented
capabilities as well as integration with iOS and other Apple products and services. Apple
announced the Apple Watch with three "collections" such as the Apple Watch, Apple Watch
Sport and Apple Watch Edition The watch will be distinguished by different combinations of
cases and interchangeable bands. The watch relies on a connected iPhone to perform many of its
functions and will be compatible with the iPhone 5 or later models running iOS 8.2 or later. The
device is available to pre-order on April 10[5] and scheduled to begin shipping April 24, 2015.
A device you wear is vastly different from one you keep on a desk or carry in your
pocket. It’s more than a tool. It’s a very personal expression. So we designed Apple Watch to
reflect a wide range of stylistic preferences. And we’ve curated three distinctive collections to
help you find the watch that’s right for you.

A smartwatch (or smart watch) is a computerized wristwatch with functionality that is
enhanced beyond timekeeping. While early models can perform basic tasks, such as calculations,
translations, and game-playing, modern smartwatches are effectively wearable computers. Many
smartwatches run mobile apps, while a smaller number of models run a mobile operating system
and function as portable media players, offering playback of FM radio, audio, and video files to
the user via a Bluetooth headset. Some smartwatches models, also calledwatch phones, feature
full mobile phone capability, and can make or answer phone calls.

OVER VIEW
2.1 DEVELOPING FOR APPLE WATCH
With Apple Watch, users can now access data in a way that is both distinctly personal
and unobtrusive. Without having to pull an iPhone out of a pocket, users can get important
information quickly just by glancing at their Apple Watch (2.1).
Figure 2.1 THE APPLE WATCH HOME SCREEN
Apple Watch requires the presence of an iPhone to run third-party apps. To create a third-
party app, you need two separate bundles: a WatchKit app (that runs on Apple Watch) and a
WatchKit extension (that runs on the user’s iPhone). The WatchKit app contains only the
storyboards and resource files associated with your app’s user interface. The WatchKit extension
contains the code for managing the WatchKit app’s user interface and for responding to user
interactions.User interactions are what make the Apple Watch unique. First, you always provide
users with a full-app experience, which they interact with by opening your app from the Home
screen.

I WATCH
Finally, youcan change the way local and remote notifications are displayed to your users
by providing custom notification interfaces. Because a WatchKit app extends the behavior of
your existing iOS app, the WatchKit app and WatchKit extension are bundled together and
packaged inside your iOS app bundle. During installation of your iOS app, the system prompts
the user to install the WatchKit app when a paired Apple Watch is present.
2.2 CONFIGURING YOUR XCODE PROJECT
A Watch Kit app requires an existing iOS app. In the Xcode project for your iOS app,
you add a new Watch Kit app target, which configures the bundles and initial resources for your
WatchKit app and Watch Kit extension. Those bundles are then delivered as part of your iOS
app on the App Store. The WatchKit app target provided by Xcode contains everything you need
to get started creating your WatchKit app, glances, and custom notification interfaces. And iOS
Simulator provides you with a runtime environment for testing the appearance and behavior of
all of your interfaces.
You must have an existing iOS app to create a WatchKit app. The WatchKit app is
implemented as a separate target of your Xcode project and is built and packaged inside your
iOS app’s bundle.
To add a WatchKit app target to your existing iOS app project
1. In Xcode, open the project for your iOS app.
2. Select File > New > Target, and navigate to the Apple Watch section.
3. Select WatchKit App, then click Next.
4. If you plan to implement a glance or custom notification interface, select the appropriate
checkboxes. For notification interfaces, it is recommended that you select the Include
Notification Scene checkbox, even if you do not plan on implementing that interface right
away. Selecting that checkbox adds an additional file to your project for debugging your
notification interfaces. If you do not select that option, later you must create the file
manually.
5. Click Finish.

I WATCH
Xcode configures the targets for your WatchKit app and WatchKit extension and adds the
needed files to your iOS project. The bundle IDs for both new targets are configured
automatically, based on the bundle ID of your iOS app. The base IDs for all three bundles must
match; if you change your iOS app’s bundle ID, you must update the other bundle IDs
accordingly.
2.2.1 APP TARGET STRUCTURE
Adding a WatchKit App target to your Xcode project creates two new executables and
updates your project’s build dependencies. Building your iOS app builds all three executables
(the iOS app, WatchKit extension, and WatchKit app) and packages them together. Xcode also
creates a build scheme specifically for building and debugging only your WatchKit app.
The structure of your iOS app and WatchKit executables. The WatchKit app is packaged
inside your WatchKit extension, which is in turn packaged inside your iOS app. When the user
installs your iOS app on an iPhone, the system prompts the user to install your WatchKit app if
there is a paired Apple Watch available. iOS handles the installation process automatically and
requires no further work on your part.
Fig 2.2 THE TARGET STRUCTURE FOR A WATCHKIT APP

2.3 WATCHKIT APP ARCHITECTURE
Your WatchKit app and WatchKit extension work in tandem to implement your app’s
interface. When the user interacts with your app on Apple Watch, your WatchKit app chooses
the appropriate scene from your storyboards to handle that interaction. For example, if the user
views your app’s glance, it chooses your glance scene. After choosing the scene, WatchKit tells
the paired iPhone to launch your WatchKit extension and create the objects needed to manage
that scene. When the scene is fully configured, it is displayed on Apple Watch. This transfer of
information between the WatchKit app and WatchKit extension happens transparently behind the
scenes.
Fig 2.3 Communication between a WatchKit app and WatchKit extension
2.3.1 WATCH KIT APP LIFE CYCLE
User interactions with Apple Watch drive the launching of your app and its life cycle.
The user can launch your app from the Home screen, interact with your glance, or view
notifications using your custom UI. Each of these interactions launches your WatchKit app and
the corresponding Watch Kit extension.

I WATCH
Your WatchKit app and WatchKit pass information back and forth until the user stops
interacting with your app, at which point iOS suspends the extension until the next user
interaction. At launch time, WatchKit automatically loads the appropriate scene for the current
interaction. If the user views your app’s glance, WatchKit loads the glance scene from your
storyboard; if the user launched your app directly, WatchKit loads the initial scene for your app.
After it loads the scene, WatchKit asks the WatchKit extension to create the corresponding
interface controller object, which you use to prepare the scene for display to the user. Figure 2.4
shows the steps for this sequence.
Fig 2.4 LAUNCHING A WATCH KIT APP
Use your interface controller’s init and awakeWithContext: methods to load any
required data, set the values for any interface objects, and prepare your interface to be displayed.
Do not use the willActivate to initialize your interface controller. The willActivate method
is called shortly before your interface is displayed onscreen, so you should use that method only
to make last-minute changes. For example, you might also use that method to start animations or
start other tasks that should only happen while your interface is onscreen.

I WATCH
While your interface controller is onscreen, user interactions are handled by your
interface controller’s custom action methods. As the user interacts with tables, buttons, switches,
sliders, and other controls, WatchKit calls your action methods so that you can respond. You use
those action methods to update your interface or perform other relevant tasks. To perform tasks
at other times, use an NSTimer object to run code at the time you designate. Your WatchKit
extension remains running only while the user is interacting with your app on Apple Watch.
Interactions with Apple Watch are meant to be brief, so interface controllers should be
lightweight and never perform long-running tasks. When the user exits your app explicitly or
stops interacting with Apple watch, iOS deactivates the current interface controller and suspends
your extension, as shown in Figure 2.5
Fig 2.5 THE LIFE CYCLE OF AN INTERFACE CONTROLLER
2.4 LEVERAGING IOS TECHNOLOGIES
WatchKit extensions have access to the same technologies found in iOS apps but because
they are extensions, the use of some technologies may be restricted and the use of others is not
recommended. Here are some guidelines for deciding when to use a particular technology:
 Avoid using technologies that request user permission, like Core Location. Using the
technology from your WatchKit extension could involve displaying an unexpected
prompt on the user’s iPhone the first time you make the request. Worse, it could happen
at a time when the iPhone is in the user’s pocket and not visible.
 Do not use background execution modes for a technology. WatchKit extensions run
only while the user interacts with the corresponding WatchKit app and are therefore

I WATCH
considered foreground extensions. As a result, WatchKit extensions cannot execute using
the background modes supported by some technologies.
 Avoid performing long-running tasks with a technology. A WatchKit extension is
suspended soon after the user stops interacting with the corresponding WatchKit app.
Because WatchKit app interactions are typically brief, the extension might already be
suspended by the time the requested data arrives.
CHAPTER 3
WATCHKIT APPS

I WATCH
3.1 UI ESSENTIALS
The starting point for implementing your app is to define your storyboard scenes. Each
scene defines a portion of your app’s user interface. You can customize scenes for different
Apple Watch sizes, and you can configure different aspects of your interface.
WatchKit apps do not use the same layout model as iOS apps. When assembling the
scenes of your WatchKit app interface, you do not create view hierarchies by placing elements
arbitrarily in the available space. Instead, as you add elements to your scene, Xcode arranges the
items for you, stacking them vertically on different lines. At runtime, Apple Watch takes those
elements and lays them out for you based on the available space.
Although Xcode handles the overall layout of your interface, WatchKit provides ways to
fine tune the position of items within a scene. The size and position of most items can be
configured using the Attributes inspector. Changing the position of an item changes lets you set
the horizontal and vertical alignment of that item at its current location in the element stack.
Fig 3.1 INTERFACE OBJECTS IN XCODE
Figure 3.1shows how you can arrange different elements in your storyboard file. The first
three elements are labels, which have different alignments within the interface controller’s
bounds. Below the labels is a group object containing two images arranged horizontally. The
interface also contains a separator and a button stacked vertically underneath the group object.

I WATCH
3.2 INTERFACE NAVIGATION
For WatchKit apps with more than one screen of content, you must choose a technique
for navigating between those screens. WatchKit apps support two navigation styles, which are
mutually exclusive:
 Page based. This style is suited for apps with simple data models where the data on each
page is not closely related to the data on any other page. A page-based interface contains
two or more independent interface controllers, only one of which is displayed at any
given time. At runtime, the user navigates between interface controllers by swiping left or
right on the screen. A dot indicator control at the bottom of the screen indicates the user’s
current position among the pages.
 Hierarchical. This style is suited for apps with more complex data models or apps whose
data is more hierarchical. A hierarchical interface always starts with a single root
interface controller. In that interface controller, you provide controls that, when tapped,
push new interface controllers onto the screen.
Although you cannot mix page-based and hierarchical navigation styles in your app, you
can supplement these base navigation styles with modal presentations. Modal presentations are a
way to interrupt the current user workflow to request input or display information. You can
present interface controllers modally from both page-based and hierarchical apps. The modal
presentation itself can consist of a single screen or multiple screens arranged in a page-based
layout.
3.3 TEXT AND LABELS
To display text in your WatchKit app, use label objects. Labels support formatted text
that can be changed programmatically at runtime.

I WATCH
To add a label to your interface controller, drag it into the corresponding storyboard
scene. From there, configure the label’s initial text string and format. WatchKit supports both
standard fonts and custom fonts that you specify yourself. Figure 3.2 shows the standard font
styles available for you to use.
FIG 3.2 STANDARD FONT STYLES FOR LABELS
3.4 CONTEXT MENUS
The Retina display with Force Touch found on Apple Watch provides a new way to
interact with content. Instead of just tapping items on the screen, pressing the screen with a small
amount of force activates the context menu (if any) associated with the current interface
controller. Context menus are optional. You use them to display actions related to the current
screen. WatchKit displays the menu over your content, as shown in Figure 3.3.

I WATCH
FIG 3.3 A CONTEXT MENU WITH THREE ITEMS
A context menu can display up to four actions. Each action is represented by a title string
and an image. Tapping an action’s image dismisses the menu and executes the action method
associated with that menu item. Tapping anywhere else dismisses the menu without any further
action.
3.5 SETTINGS
Preferences and settings are data values that change infrequently and that you use to
configure your app’s behavior or appearance. If your WatchKit app uses preferences for its
configuration, you can add a WatchKit–specific settings bundle to your project to present those
settings to the user. This settings bundle lives inside your containing iOS app, and the settings
themselves are displayed by the Apple Watch app on the user’s iPhone.
A WatchKit settings bundle works in the same way that an iOS settings bundle works.
The settings bundle defines the controls you want displayed by the system and the name of the
preference that each control modifies. The Apple Watch app on the user’s iPhone takes your
settings bundle information and uses it to display the actual controls to the user. When the user
changes the value of a control, the system updates the underlying preference value.

I WATCH
3.6 GLANCE ESSENTIALS
A glance is a supplemental way for the user to view important information from your
app. Not all apps need a glance. A glance provides immediately relevant information in a timely
manner. For example, the glance for a calendar app might show information about the user’s
next meeting, whereas the glance for an airline app might display gate information for an
upcoming flight. Figure 3.4 shows the glance for the Lister sample app, which displays the
number of completed items and the number of remaining items on the user’s to-do list.

DESIGN ASPECTS
A device you wear is vastly different from one you keep on a desk or carry in your
pocket. It’s more than a tool. It’s a very personal expression. So we designed Apple Watch to
reflect a wide range of stylistic preferences. And we’ve curated three distinctive collections to
help you find the watch that’s right for you
The Apple S1 is an integrated computer designed by Apple and as such it includes
memory, storage and support circuits like wireless modems and I/O controllers in a sealed
integrated package. It was announced on 9th of September 2014 as part of the "Wish we could
say more" event. It will make its first appearance within the Apple Watch arriving in early 2015.
FIG 4.1 APPLE S1 CHIP
Everyone’s style is different, as is everyone’s wrist. So Apple Watch comes in two case
sizes: 38mm and 42mm.

6.2 DISADVANTAGES
 NO INDEPENDENT USAGE
The main disadvantage of the iWatch is that it has to be synchronised with the iPhone and
cannot be used independent of it. So, if you want to own a iWatch you need to get
yourself an iPhone.
 BATTERY
Not much was said about the iWatch battery and how long will it last as it is very crucial
hardware.
CONCLUSION
The Apple Watch will work with Apple Pay. A mobile payment service introduced at the
same event as the Watch. The Apple Watch is capable of receiving phone calls as well
as iMessage and SMS Texts. The Apple Watch can track fitness, run third-party apps and use an
Apple feature called "Handoff" (see iOS 8) as long as you own another Apple device. It can

I WATCH
control theApple TV, as well as act as a walkie-talkie and a viewfinder for an iPhone camera.
