Page indicator in tabview swiftui

I'am using tabView to display some onboarding screens in my app. I was using

  .onAppear() {
                UIPageControl.appearance().currentPageIndicatorTintColor = .black
                UIPageControl.appearance().pageIndicatorTintColor = .gray
            }

to modify the background of the indicators and color. But now page indicator not showing in iOS 14.5 devices.

Referred this Link and other multiple links , but it says to add constraints. How to do that in swiftUI?

Solution

  • 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
    }
}
