func didFinishProgress()

SwiftUI

struct PhotoView: View {

    @State var isRecording: Bool = false
    @State var didFinishProgress: Bool = false

    var body: some View {
        CameraButtonUI(
            size: 72,
            borderColor: .red,
            fillColor: (.purple, .orange),
            progressColor: .green,
            progressDuration: 5,
            isRecording: self.$isRecording
        )
        // Handle tap gesture
        .simultaneousGesture(
            TapGesture()
                .onEnded { _ in
                    print("tap")
                }
        )
        // Start recording on Long-press gesture
        .gesture(
            LongPressGesture(minimumDuration: 1)
                .onChanged { val in
                    isRecording = true
                }
        )
        // Observe state changes
        .onChange(of: isRecording, perform: { [isRecording] newValue in
            print("isRecording", isRecording, newValue)
        })
    }
}
