I write macOS menu app with TextField by SwiftUI on Japanese Input mode. On some conditions, the TextFiled lost focus, no key input, no mouse click. User cannot do anything.
Setup
MacOS Ventura 13.3.1 (a)
Install Japanese Romaji Input source by System Preferences -> Keyboard
Set input mode as "Romaji"
Build test source code
On Xcode 14.3, create new macOS app project "FocusTest" with SwiftUI, Swift.
Replace FocusTestApp.swift with attached code.
Build on Xcode
Steps
Set input mode as "Romaji"
Run FocusTestApp
Click T square icon on top menu
Small windows with globe appear
Click Desktop background area
Click T square icon on top menu
Click PIN
T with PIN textField View appear
That textField lost focus, click inside of textField
Key or click is not accepted.
With US keyboard mode, key input become possible on Step 10. But Focused blue square is missing.
Code of FocusTestApp.swift
import SwiftUI
@main
struct focusTestApp: App {
var body: some Scene {
MenuBarExtra("Test", systemImage: "t.square") {
MainView()
}.menuBarExtraStyle(.window)
}
}
struct MainView: View {
@State private var showingPIN: Bool = false
var body: some View {
VStack {
Image(systemName: "globe")
.imageScale(.large)
.foregroundColor(.accentColor)
Button("PIN") {
print("clicked")
showingPIN = true
}
}
.padding()
.sheet(isPresented: $showingPIN) {
PinView()
}
}
}
struct PinView: View {
@Environment(\.presentationMode) var presentationMode
@State private var pin: String = ""
@FocusState private var pinIsFocused: Bool
var body: some View {
VStack {
Image(systemName: "t.square")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 64.0, height: 64.0)
.foregroundColor(.accentColor)
Text("Enter PIN code")
HStack {
TextField("", text: $pin)
.font(Font.system(size: 28, design: .default))
.frame(width:4*28.0, height:28.0)
.focusable()
.focused($pinIsFocused)
}
.onAppear(){
pinIsFocused = true
}
}
.padding()
}
}
