Hi everyone, im in the process of delving more into coregraphics with swiftui, but I am at a roadblock. First I would like to ask, what are some good resources to learn coregraphics? Secondly: I currently have a circle view made and what I want to do is to make my circle view modular so that it can be directly connected to another given circle by a line. How can I do this? For example, I want my circles to represent nodes and be able to connect by lines to other nodes that are related. Thanks in advanced. Here is my code for the circle view: @State private var circleProgress: CGFloat = 0 let timer = Timer.publish(every: 0.016, on: .main, in: .common).autoconnect() private let animationDuration: TimeInterval = 1.5 @Binding var startPoint: CGPoint @Binding var endPoint: CGPoint var body: some View { GeometryReader { geometry in Canvas { context, size in // Circle parameters let circleSize: CGFloat = 50 let circleOrigin = CGPoint( x: size.width / 4, y: size.height / 2 - circleSize / 2 ) let circleRect = CGRect( origin: circleOrigin, size: CGSize(width: circleSize, height: circleSize) ) let circleCenter = CGPoint( x: circleOrigin.x + circleSize / 2, y: circleOrigin.y + circleSize / 2 ) // Animate circle creation var circlePath = Path() circlePath.addArc( center: circleCenter, radius: circleSize / 2, startAngle: .degrees(0), endAngle: .degrees(360 * circleProgress), clockwise: false ) context.addFilter(.shadow(color: .white.opacity(0.6), radius: 5, x: 1, y: 1)) // Add white shadow context.stroke( circlePath, with: .linearGradient( Gradient(colors: [.purple, .white]), startPoint: circleRect.origin, endPoint: CGPoint(x: circleRect.maxX, y: circleRect.maxY) ), lineWidth: 5 ) } .frame(width: 300, height: 150) .onReceive(timer) { _ in // Update circle progress let progressChange = 0.02 / animationDuration if circleProgress < 1.0 { circleProgress = min(circleProgress + progressChange, 1.0) } else { circleProgress = 0.0 // Reset the circle to repeat the animation } // Get the starting and ending points of the Canvas view startPoint = CGPoint(x: geometry.frame(in: .global).minX, y: geometry.frame(in: .global).minY) endPoint = CGPoint(x: geometry.frame(in: .global).maxX, y: geometry.frame(in: .global).maxY) // Print the points for debugging print("Start Point: \(startPoint.x), \(startPoint.y)") print("End Point: \(endPoint.x), \(endPoint.y)") } } .frame(width: 300, height: 150) } }

I am trying to upload my app to the app store, but app review says that nothing is happening when they click my "purchase" button for my subscription paywall. I have tested my subscription button process on my local device numerous times, with a sandbox account and never a problem. For context, I am using revenuecat to process my payments here. Any advice on testing IAP's, edge cases that could cause this problem, or anything that could help me solve this? Thank you!
