SwiftUI Animated view with rotation, has problem as it moves up and down
Hi, so I've a simple loader animation, but when I present the animation from a NavigationLink, just for showcase, the view moves up and down, it works fine in the view preview, but simulator and devices have this issue. struct SystemDesignView: View { var body: some View { NavigationStack { List { Section("Animated Components WIP") { NavigationLink { LoaderView() } label: { Text("Loader") } } .navigationTitle("System Design") } } } } And here is the animated view: struct LoaderView: View { @State private var rotationAngle: Angle = .degrees(0) private var lineWidth = 2.0 private var lenght = 42.0 var body: some View { ZStack { // Full circle Circle() .strokeBorder(Color.electric.opacity(0.1), lineWidth: lineWidth) .frame(width: lenght, height: lenght) .background(Color.clear) // Quarter circle Circle() .trim(from: 0.0, to: 0.25) .stroke(Color.electric.opacity(1.0), style: StrokeStyle(lineWidth: lineWidth, lineCap: .round, lineJoin: .round)) // Rounded corners .frame(width: lenght - lineWidth, height: lenght - lineWidth) .rotationEffect(rotationAngle, anchor: .center) } .onAppear() { withAnimation(Animation.linear(duration: 1.0).repeatForever(autoreverses: false)) { rotationAngle = .degrees(360) } } } } struct LoaderView_Previews: PreviewProvider { static var previews: some View { LoaderView() } } Any idea?, thanks

GraphQL on iOS
Hi, I'm starting to look into GraphQL and how to support it natively on my apps, most tutorials online are about using Apollo, but I rather not introduce third party code at this point. Does someone knows any reference I can use? Thank you
