watchkit

In my project I want to use one Realm Database with my iOS 10 application and my watchOs 3 application at the same time. So what I did was adding the frameworks to the embedded binaries for the three different targets. This happened to work very well but the watchKit extension doesn't seem to recognize the objects that I created within the iOS environment. How is it possible to have a shared Realm Database between those two devices? TiM Update: Okay, thanks to chrisamanse 's heads-up, I did some more research on this. It turns out that App Groups are no longer possible on watchOS 2. Watch apps

I am wondering how to go about designing a watchOS app that depends on getting the latest feed from a server. Would you need to use application context and just have the iPhone push it over in the background using the WatchConnectivity framework or would you use NSURLSession on the Apple Watch itself? Keep in mind this is for watchOS 2. You can use NSURLSession to handle your request. So your request would be native on your watchn. But note that your watch is there to show simple Content to the user. 来源： https://stackoverflow.com/questions/31465130/getting-server-data-for-the-apple-watch

I'm trying to change label font. But every font I set in the Attributes Inspector different from the system font - don't change anything - neither simulator or storyboard. I even tried to set the font programatically with Attributed string - the same System font appears. Thanks for your help. You cannot use the included iOS fonts in WatchKit at this time. The only one available is System (San Francisco). Source: Apple Developer Forums You can however use a custom font by adding the font file to the project: Drag the font files into the project navigator Include the custom font file in both

Submitting WatchKit 1.2 companion app, fails during validation with this error: ERROR ITMS-90455 "Invalid WatchKit App Bundle. The value '2.1' for the MinimumOSVersion key in info.plist in bundle 'redactedbundlename.watchkitapp' is not supported" I do cannot find a MinimumOSVersion key in the watch app plist or settings, nor in build settings or plist for the phone app. The only mention of anything "2.1" related is in my build settings: Any ideas to diagnose this issue? Fixed it! For some reason, you need to change WATCHOS_DEPLOYMENT_TARGET from 2.1 to 2.0 . You can find this in Project

Is there a more elegant solution to load an external image on the watch than the following ? let image_url:String = "http://placehold.it/350x150" dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) { let url:NSURL = NSURL(string:image_url)! var data:NSData = NSData(contentsOfURL: url)! var placeholder = UIImage(data: data)! // update ui dispatch_async(dispatch_get_main_queue()) { self.imageView.setImage(placeholder) } } NSURL is meant to be used for local files. Instead use NSURLSession. It's also useful to set the scale for the remote image. import WatchKit public

I have an interface with 2 buttons, both of them call the same interface but with different information. On the traditional interface I use prepareForSegue, but I don't know what's the equivalent one on the WatchKit. You can do this in two ways: In your storyboard you set an identifier in your segue: and then you can use contextForSegueWithIdentifier : - (id)contextForSegueWithIdentifier:(NSString *)segueIdentifier { if ([segueIdentifier isEqualToString:@"yourIdentifier"]) { return aDictionaryWithYourInformation; } } Or you can pass information with a context via code, with: [self
