When the Apple TV is off, is it possibile to turn on it (and the tv attached to it via HDMI) with a remote push notification from a server from an app?
Hello. I have Navigation View with a List and 2 cells like this:NavigationView {
List{
NavigationLink(destination: TabScene()) {
// Cella 1
HStack {
Image(title[0].icon)
Text(title[0].title).font(.system(size: 30))
}
}
// Cella 2
HStack {
Image(title[1].icon)
Text(title[1].title).font(.system(size: 30))
} // Con la tap sulla cella si attiva la State var a true
.onTapGesture {
self.showTabView.toggle()
} // Quando la state var va a true si presenta la scena desiderata.
.sheet(isPresented: $showTabView, content: {
CreditsView()
})
}
.navigationBarTitle("ARPlanets 2")
.navigationViewStyle(DefaultNavigationViewStyle())
.listStyle(GroupedListStyle())
}Currently the background is white and it becomes black with the dark mode. Anyway i want to choose a custom background Color for my app. How can i do that? So far i could not set a background Color for the Navigation View with a List embed inside it.
I saw that the Core NFC framework is only available for iOS and Mac Catalyst.Therefore is it possible to make a watchOS app able to read NFC tags?Best regards.
Hi,Is it possibile to make a watchOS 6 app that establish a Socket TCP Connection?Like what i did in iOS by using the CocoaAsyncSocket networking library.
I'm developing a watchOS 6 standalone app with Xcode and Objective-C. This app should connect to a TCP server. If I run the app on the simulator it works, if I run it on my physical Apple Watch Series 4 I get this error: The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -72000).Here is the code:InterfaceController.h#import <WatchKit/WatchKit.h>
#import <Foundation/Foundation.h>
@interface InterfaceController : WKInterfaceController <NSStreamDelegate>
