SwiftUI TabView Page Styling - swift

Question

I am using a tab view with PageTabViewStyle to list out colors of a shirt, but the tab bar is barely visible with lighter color shirts and only shows the top half on darker. Is it possible to give the bar a background or change the dot color?
I've tried:
init() {
UITabBar.appearance().barTintColor = .darkGray
}
But it didn't work.
Full Code:
struct PrintifyProductCell: View {
var product: PrintifyProduct
var images: [PrintifyImages] {
product.images.filter { $0.position == "front" }
}
#State private var animating = true
#State private var selected = 0
var body: some View {
VStack {
TabView(selection: $selected) {
ForEach(images.indices, id: \.self) { index in
AsyncImage(url: URL(string: images[index].src)!) { image in
image
.resizable()
.frame(minWidth: 120, idealWidth: 160, maxWidth: 160, minHeight: 130, idealHeight: 180, maxHeight: 180, alignment: .center)
.cornerRadius(8)
.tag(index)
} placeholder: {
LoadingView(isAnimating: $animating)
.frame(width: 40, height: 40)
}
}
.frame(minWidth: 120, idealWidth: 160, maxWidth: 160, minHeight: 130, idealHeight: 180, maxHeight: 180, alignment: .center)
}
.tabViewStyle(PageTabViewStyle())
.frame(minWidth: 120, idealWidth: 160, maxWidth: 160, minHeight: 130, idealHeight: 180, maxHeight: 180, alignment: .center)
.cornerRadius(8)
.padding(.horizontal, 6)
.padding(.top, 6)
Text(product.title)
}
.background(Color(UIColor.uStadium.lightGray))
.cornerRadius(8)
}
}
