If you are new to this WatchOS series then please read our blog <a href=\"https:\/\/9series.com\/blog\/fundamental-concept-of-watchos-ios-application-developers-india\/\" target=\"_blank\">Fundamental Concept of WatchOS.<\/a><\/p>\n<p><a href=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2017\/02\/DATA-SHARING-INSIGHTS-OF-WATCHOS.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1939\" src=\"https:\/\/9series-blog.staging9.com\/wp-content\/uploads\/2017\/02\/DATA-SHARING-INSIGHTS-OF-WATCHOS.jpg\" alt=\"DATA SHARING INSIGHTS OF WATCHOS\" width=\"800\" height=\"400\" \/><\/a><\/p>\n<p>In this article, we will look about data sharing methods across Apple Watch and iOS app. Also we will check for background tasks, Apple Pay Enhancement, WatchOS Connectivity framework, What\u2019s new in WatchOS 3.0, etc.<\/p>\n<p>So, let\u2019s start with further more features and updates for WatchOS:<\/p>\n<p>Different Methods of Sharing Data Between WatchKit and iOS App<\/p>\n<ul>\n<li>MMWormhole Library<\/li>\n<li>NSUserDefault<\/li>\n<li>WatchKit connectivity Framework<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold\">What\u2019s New in WatchOS 3.0<\/span><\/p>\n<p>With the upcoming WatchOS 3 update to all Apple Watch devices, the performance of many watch applications is definitely going to improve. This is mainly due to the new forms of background execution where watchOS apps can take advantage in order to refresh their content periodically and always have the latest information that is ready to be viewed by the user.<\/p>\n<p><span style=\"font-weight: bold\">1. Background Task<\/span><\/p>\n<p>Background tasks give your app time to keep running out of sight and ensure that the information user needs is accessible before they open your app. WatchOS 3 introduces several types of background tasks:<\/p>\n<p><span style=\"font-weight: bold\">Background App Refresh<\/span><\/p>\n<p>Utilize the WKApplicationRefreshBackgroundTask class to update your app\u2019s status in the background. You frequently use a background app refresh task to manage other tasks. For example, you might use a background app refresh task to start an NSURLSession background transfer or to schedule a background snapshot refresh task.<\/p>\n<ul>\n<li><span style=\"font-weight: bold\">Background Snapshot Refresh<\/span><br \/>\nUtilize the WKSnapshotRefreshBackgroundTask class to modify your app\u2019s user interface. You can push, pop, or present other interface controllers, and then modify the content of the desired interface controller. The system naturally takes a snapshot of your user interface as soon as this task completes.<\/li>\n<li><span style=\"font-weight: bold\">Background Watch Connectivity<\/span><br \/>\nWhen you receive background data from the paired iPhone, the system initiates your app in the background, instantiates a WKWatchConnectivityRefreshBackgroundTask object, and passes the task object to your extension delegate\u2019s handleBackgroundTasks: method.<\/li>\n<li><span style=\"font-weight: bold\">Background URL Session<\/span><br \/>\nWhen a background transfer needs authorization, or when a background transfer finished (successfully or unsuccessfully), the system creates a background NSURLSession event, instantiates a WKURLSessionRefreshBackgroundTask object, and moves the task object to your extension delegate\u2019s handleBackgroundTasks: method.<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold\">2. Apple Pay Enhancement<\/span><\/p>\n<p>In WatchOS 3, the PassKit framework (PassKit.framework) includes support for in-app payments on Apple Watch. In-app payments enable users to securely provide payment and contact information to pay for physical goods and services.<\/p>\n<p><span style=\"font-weight: bold\">3. Watch Connectivity Framework Enhancements<\/span><\/p>\n<p>The WatchConnectivity framework introduced in WatchOS 2 and iOS 9 is likewise increasing some new functionality with WatchOS 3 and iOS 10.<\/p>\n<p>If a user has placed your app&#8217;s complexity on their watch face, then you can transfer data from the phone to the watch up to 50 times in a single day. But while transferring, if the data goes beyond the limit of 50, then the user will get notifications about the exceeded limit. This is done, as in iOS 9 and WatchOS 2, via the WCSession transferCurrentComplication(userInfo:) instance method. The new functionality in watchOS 3 and iOS 10 is the WCSession remainingComplicationUserInfoTransfers property, which will show you how many transfers are left for that day.<\/p>\n<p>Another new WCSession property added is the hasContentPending property, which is just a boolean value signifying whether or not there is data yet to be transferred between the iPhone and Apple Watch.<\/p>\n<p><span style=\"font-weight: bold\">4. Existing Frameworks now available in WatchOS<\/span><\/p>\n<ul>\n<li>SceneKit Framework<\/li>\n<li>SpriteKit Framework<\/li>\n<li>AVFoundation Framework<\/li>\n<li>CloudKit Framework<\/li>\n<li>Core Audio Framework<\/li>\n<li>GameKit Framework<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold\">5. SnapShot and Dock<\/span><\/p>\n<p>In WatchOS 3, app sights have been removed entirely from the Apple Watch and instead have been displaced by the dock, which provides a rapid way for users to view and launch their favorite apps. After pressing the side button to show the Dock, users scroll through it to view snapshots of their favorite apps. When users stop scrolling and let the Dock settle for a moment, the promoted app wakes and the snapshot gets replaced by the running app.<\/p>\n<p>The system automatically takes periodic snapshots of your app and uses them to populate the Dock and to serve as your app\u2019s launch image. You can modify both the currently presented interface controller &amp; the controller\u2019s content before the snapshot is taken.<\/p>\n<p><span style=\"font-weight: bold\">6. Control Center<\/span><\/p>\n<p>Provides support for all-new Control Center which can be invoked by sliding up from the bottom of the screen.<\/p>\n<p><span style=\"font-weight: bold\">7. New Watch Faces<\/span><\/p>\n<p>Adds new watch faces and adds support for switching between them by swiping left\/right from the edge of the watch screen.<\/p>\n<p><span style=\"font-weight: bold\">8. Activity\/Workouts<\/span><\/p>\n<p>Adds support for sharing an activity with friends using iMessage or other messaging platforms.<\/p>\n<p>Adds support for tracking the progress of people in wheelchairs, showing a &#8220;Time to Roll&#8221; reminder rather than &#8220;Time to Walk&#8221; as watchOS 2 did. It is now conceivable to see 5 different workout metrics all at once. This includes distance, pace, active calories, heart rate, and elapsed time. Adds support for delaying a workout when halted at a stoplight. Support for another Breathe app guides users through a set of deep breaths to help them be more comfortable.<\/p>\n<p><span style=\"font-weight: bold\">9. SOS<\/span><\/p>\n<p>Adds support for a feature called SOS which allows a person to place emergency calls by holding the side button for 5 seconds.<\/p>\n<p>Give us a chance to check with some convenient question-answers.<\/p>\n<p><span style=\"font-weight: bold\">FAQ<\/span><\/p>\n<p><span style=\"font-weight: bold\">1. How many Apple Watch can I pair with one iPhone?<\/span><\/p>\n<ul>\n<li>You can pair one Apple Watch with one iPhone at a time &#8211; It\u2019s an Exclusive Relationship<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold\">2. What is the maximum size for WatchKit App?<\/span><\/p>\n<ul>\n<li>The maximum size for WatchKit app is 30 MB.<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold\">3. Can I play video on Watch App?<\/span><\/p>\n<ul>\n<li>You can play short video with low frame rate.<\/li>\n<\/ul>\n<p><span style=\"font-weight: bold\">4. Can I fetch contact in WatchKit app?<\/span><\/p>\n<ul>\n<li>You can add only 3 emergency contacts in Apple watch.<\/li>\n<\/ul>\n<p>A debt of gratitude is in order for your opportunity to peruse this article and constantly running over our blog.
