Since there is no horizontal Picker built into SwiftUI*, how are you doing this? Are you putting everything into an HStack? That would cause the items to be squeezed as you describe. I think you would need to create your own custom horizontal Picker, maybe using a ScrollView to display the items and a GeometryReader to achieve effects like dimming the items near the edges and so forth.

I don't know if something could be done with a custom PickerStyle, but maybe. I haven't had a need to play around with that yet.

• Well, I suppose the SegmentedPickerStyle creates a horizontal Picker, but it's not intended to scroll so if you put a lot of items into it, everything will get smooshed. No way around that, really.

You would have to use an onTapGesture handler.

A very simple example:

import SwiftUI

struct HScroller: View {
    @State private var bgndColor = Color.white

    var body: some View {
        ZStack {
            bgndColor
                .edgesIgnoringSafeArea(.all)
            ScrollView(.horizontal, showsIndicators: false) {
                HStack {
                    ForEach(0..<10, id: \.self) { idx in
                        ZStack {
                            Circle()
                                .fill(self.bgndColor)
                                .colorInvert()
                                .frame(width: 50, height: 50)
                                .padding()
                            Text("\(idx)")
                                .foregroundColor(.white)
                                .bold()
                        }
                        .onTapGesture {
                            self.bgndColor = Color(red: Double.random(in: 0...1.0), green: Double.random(in: 0...1.0), blue: Double.random(in: 0...1.0))
                        }
                    }
                }
            }
        }
    }
}
