I have a simple SwiftUI app that has a picker, textfield and several buttons. It is using a Enum as a focus state for the various controls.
When I compile and run it on Mac Studio desktop it works as expected:
Picker has initial focus,
Selection in Picker changes focus to TextField,
Tab key moves through buttons; last button resets to Picker
However when I run the exact same app on MacBook Pro (same version of MacOS, 14.5) it does not work at all as expected. Instead:
Initial focus is set to TextField,
Tab does not change the focus,
Clicking on last button resets focus to TextField rather than Picker
The content view code:
enum FFocus: Hashable {
case pkNames
case btnAssign
case tfValue
case btn1
case btn2
case noFocus
}
struct PZParm: Identifiable {
var id = 0
var name = ""
}
struct ContentView: View {
@State var psel:Int = 0
@State var tfVal = "Testing"
@FocusState var hwFocus:FFocus?
var body: some View {
VStack {
Text("Hardware Test").font(.title2)
PPDefView(bSel: $psel)
.focused($hwFocus, equals: .pkNames)
TextField("testing", text:$tfVal)
.frame(width: 400)
.focused($hwFocus, equals: .tfValue)
HStack {
Button("Button1", action: {})
.frame(width: 150)
.focused($hwFocus, equals: .btn1)
Button("Button2", action: {
tfVal = ""
hwFocus = .tfValue
})
.frame(width: 150)
.focused($hwFocus, equals: .btn2)
Button("New", action: {
tfVal = ""
hwFocus = .pkNames
})
.frame(width: 150)
.focused($hwFocus, equals: .btnAssign)
}
}
.padding()
// handle picker change
.onChange(of: psel, {
if psel > 0 {hwFocus = .tfValue}
})
.onAppear(perform: {hwFocus = .pkNames})
}
}
#Preview {
ContentView()
}
struct PPDefView: View {
@Binding var bSel:Int
// test defs
let pzparms:[PZParm] = [
PZParm.init(id:1, name:"Name1"),
PZParm.init(id:2, name:"Name2")
]
//
var body:some View {
Picker(selection: $bSel, label: Text("Puzzle Type")) {
ForEach(pzparms) {Text($0.name)}
}.frame(width: 250)
}
}
