Environment
macOS: 26.2 (25C56)
Xcode: 26.2 (17C52)
Steps to reproduce
Run the project
Open app's 'Settings
Look at the console logs
When model is created SettingsModel - init gets printed
When Settings window is closed SettingsModel - deinit is not printed, meaning it is not deallocated
Code
SettingsModel
import SwiftUI
@Observable
class SettingsModel {
init() {
print("SettingsModel - init")
}
deinit {
print("SettingsModel - deinit")
}
}
SettingsView
import SwiftUI
struct SettingsView: View {
@State var model = SettingsModel()
var body: some View {
Text("Settings")
.font(.largeTitle)
.padding(200)
}
}
App
import SwiftUI
@main
struct SettingsBugApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
Settings {
SettingsView()
}
}
}
