Picker(selection: $preferenceManager.preference.display, label: EmptyView()) {
Image("grid")
.resizable()
.padding()
.tag(0)
Image("list")
.resizable()
.tag(1)
}.pickerStyle(SegmentedPickerStyle())
.frame(width: 50)
.padding(.leading, 16)
.padding(.trailing, 24)

Alternatively, we can make custom NSSegmentedControl

import AppKit
import SwiftUI

struct MySegmentControl: NSViewRepresentable {
func makeCoordinator() -> MySegmentControl.Coordinator {
Coordinator(parent: self)
}

func makeNSView(context: NSViewRepresentableContext<MySegmentControl>) -> NSSegmentedControl {
let control = NSSegmentedControl(
images: [
NSImage(named: NSImage.Name("grid"))!,
NSImage(named: NSImage.Name("list"))!
],
trackingMode: .selectOne,
target: context.coordinator,
action: #selector(Coordinator.onChange(_:))
)
return control
}

func updateNSView(_ nsView: NSSegmentedControl, context: NSViewRepresentableContext<MySegmentControl>) {

}

class Coordinator {
let parent: MySegmentControl
init(parent: MySegmentControl) {
self.parent = parent
}

@objc
func onChange(_ control: NSSegmentedControl) {

}
}
}
