Change Tabview Indicator Swiftui

change TabView indicator SwiftUI

you need to use UIkit

 init() {
    UIPageControl.appearance().currentPageIndicatorTintColor = .red
    UIPageControl.appearance().pageIndicatorTintColor = UIColor.black.withAlphaComponent(0.2)
    }

Move Index View above home indicator in Tab View

EDIT: See also @nekno's fantastic additions!

This is possible if you create a custom UIPageControl, manually tag each tab in the TabView, and make sure to keep track of the numberOfPages:

struct PageControlView: UIViewRepresentable {
    @Binding var currentPage: Int
    @Binding var numberOfPages: Int

    func makeUIView(context: Context) -> UIPageControl {
        let uiView = UIPageControl()
        uiView.backgroundStyle = .prominent
        uiView.currentPage = currentPage
        uiView.numberOfPages = numberOfPages
        return uiView
    }

    func updateUIView(_ uiView: UIPageControl, context: Context) {
        uiView.currentPage = currentPage
        uiView.numberOfPages = numberOfPages
    }
}

struct ContentView: View {
    @State var isSheetUp = false

    var body: some View {
        Button("Present") {
            isSheetUp.toggle()
        }
        .sheet(isPresented: $isSheetUp) {
            Sheet()
        }
    }

    struct Sheet: View {
        @State var currentPage = 0
        @State var numberOfPages = 3

        var body: some View {
            NavigationView {
                ZStack {
                    TabView(selection: $currentPage) {
                        Page().tag(0)
                        Page().tag(1)
                        Page().tag(2)
                    }
                    // Comment this to switch layout issue
                    .ignoresSafeArea(edges: .bottom)
                    .tabViewStyle(.page(indexDisplayMode: .never))
                    .indexViewStyle(.page(backgroundDisplayMode: .always))
                    .navigationTitle("Title")
                    .navigationBarTitleDisplayMode(.inline)

                    VStack {
                        Spacer()
                        PageControlView(currentPage: $currentPage, numberOfPages: $numberOfPages)
                    }
                }
            }
        }
    }

    struct Page: View {
        var body: some View {
            ScrollView {
                VStack {
                    Rectangle()
                        .foregroundColor(.teal)
                        .padding()
                        .frame(minHeight: 10000)
                }
            }.background(Color.brown)
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

TabView dot index color does not change

Use init instead of onAppear

struct TestScrollView: View {
    init() {
        UIPageControl.appearance().currentPageIndicatorTintColor = .blue
        UIPageControl.appearance().pageIndicatorTintColor = .red
        UIPageControl.appearance().tintColor = .red
    }
    var body: some View {

TabView Indicator doesn't move when page changes

The green area below does move to the right, but only 1 pixel. Try something like this example code, choose the value (200) most suited for your purpose:

.onAppear {
    self.tabOffset = CGFloat(index*200)  // <-- here
}

Page indicator in tabview swiftui

Add an init() to the View where you define the UIKit appearance.

struct YourView: View {
    init() {
        UIPageControl.appearance().currentPageIndicatorTintColor = .black
        UIPageControl.appearance().pageIndicatorTintColor = .gray
    }

    var body: some View {
        // Text("YourView") with TabView
    }
}
