Fall detection for workouts 6. New Group Workouts Now you can work out with up to 32 of your friends. Foreground sessions need to complete while your app is in the foreground or front-most, and for all but the shortest tasks, this isn't enough time.

Think about your customers' experience if their communication task fails. So, please be considerate of your customers and carefully evaluate each communication task and ask, "Can I do this in the background?

You can also send a push notification to your app to indicate that new data is available and initiate a background update. The exact timing of your background transfer will depend on system conditions.

Let's walk through an example of sending some data to a server in the background. For example, if I have some settings for my application that I want to store through my web server, when my customer saves those, I can save them on the Watch and then send them to the server in the background. To do that, I've made a background URL session class to handle the work of the server communication.

Our URL session will have a background configuration with a unique identifier we can use to find it later. Set the sends launch events property to true to indicate that the session should launch your app in the background when tasks on your session need to be handled.

Note that if you're transferring a large amount of data, you should set the isDiscretionary property of the URL session configuration to true to let the system schedule the transfer at an optimal time for the device for best performance.

In this case, you should also let your customers know that their downloads might not happen until they're connected to Wi-Fi and power. When we're ready to send the data, we need to enqueue the transfer to schedule the background session. We'll create and configure a URL request with the contents for our Settings update to our server. Then, we'll create a task for our request on the session.

In this simplified example, I'm only adding one task to my session, but you can add multiple requests to your session for efficiency. Set the earliestBeginDate to start the download later. Note that the system will determine the actual time our task starts based on background budget, network, and system conditions.

Your app can receive up to four background refresh tasks per hour, if you have a complication on the active watch face, so schedule your tasks at least 15 minutes apart to prevent them from being delayed by the system. I'm holding on to this session in a list of in-progress sessions.

This will become important later, when the system lets me know that my URL request has completed. Calling "resume" on the task actually starts it, so it's important that you call this.

Finally, I set my status to queued in case there are observers for the session. The system will notify our app when our background request has been processed using a background task sent to our Extension Delegate.

If we have it, we'll call a function on the session to add the background refresh task to the list for the session, so we can let the system know we've completed it as soon as we've finished processing the data. I'll show you this in a moment. If we don't find the session in our list, we need to mark the task as completed. It is very important that you always set your background refresh task completed as soon as you're done.

There's one more thing we need to do to get our background task calls: we need to connect our extension delegate to our App. To do this we're going to use the WK extension delegate adaptor property wrapper with our Extension Delegate class, and add a property to our app. Now, the system will call our extension delegate to handle our background tasks.

In our extension delegate, we called this function to add our background task to our existing session. Add this task to our list of background tasks so we can mark it completed as soon as we're done processing the URL data. Now, we've wired up the whole round trip, and all we have left to do is get our data and let the system know we're done. Our URL session download delegate will get called when our request completes. Process the data received in the file from the download task. It's important that you either move this item into a directory accessible to your app or quickly process the data from the file.

When this task completes, the downloaded file will be deleted. We're removing this session from the list of in-process sessions, since we won't get any more background tasks for it from the extension delegate, and we're setting the status to completed in case there are any observers.

Finally, we're setting our background task completed. This lets the system know we've completed our background processing. Making sure you do this isn't just being a good Watch app citizen. It prevents the system from terminating your app for exceeding its background limits. And that's it! We're all done sending our settings in the background and getting any updates. Note that in a full implementation, you'll want to handle errors and authentication challenges, but this gives you the basic steps.

Use foreground URL sessions for quick server communication while a person is interacting with your app. A good example of this is getting the latest workout list or the meditation of the day. Foreground URL sessions are a less-power-efficient way to get and send data, and a two-and-a-half minute timeout is enforced. But in practice, you should try to target foreground sessions to interactions that are much quicker than that limit.

URL sessions are the best method for general purpose communication directly with servers. They don't rely on a companion iPhone app, and you can use them with apps supporting Family Setup. Use background sessions for anywhere you can possibly delay the data transfer, and always for transferring larger amounts of data. To learn more about URL sessions, check out "Keep your complications up to date" and "Background execution demystified" in the Developer app or online.

In addition to URL sessions, if you're building a streaming audio app, sockets are another option to communicate directly with servers. For more information on using Sockets, check out the "Streaming Audio on watchOS 6" session in the Developer app or online. We've covered a lot, so let's summarize how we can choose from among all the options we've seen. For small pieces of sensitive data that can be synced to all a person's devices, choose Keychain with iCloud Synchronization.

To optimize the experience for companion iPhone and Watch apps, or to share data that is available only on one device in companion apps, choose Watch Connectivity. To communicate directly with servers, choose URL sessions.

Wait for the progress wheel to appear on your Apple Watch. On your watch, open the Settings app. Tap Install if a software update is available, then follow the onscreen instructions. If you need help updating Try these steps: Make sure that your Apple Watch connects to its charger. Restart your Apple Watch. Press and hold the side button until you see Power Off, then drag the slider. To turn your watch on again, press and hold the side button. Restart your paired iPhone.

Try to start the update again. If you installed an iOS or watchOS beta or developer seed Before you update, remove the beta profile from your device.

My watch constantly unlocks my phone while i'm running. Please disable "Unlock with Apple Watch" while in active motion or while doing an Outdoor Run exercise. This would be a huge improvement to this feature!

Having issues with Apple Watch app. App is on my phone but shows cloud next to it. Brings me to App Store to redownload but never completes. I have an iPhone 7 Plus. Had the Apple Watch app installed when I bought my Watch and was working fine until last month. I have other apps with the same issue like home calendar and weather.
