Thanks a lot for this answer. Been troubleshooting this bug for almost a day now, can't believe it's 2024 and Apple hasn't fixed this bug or mentioned this configuration in the developer documentation.
A week has passed and I haven't received any feedback from Apple.

I think there is something wrong with Menu in MacOS, toogle insdie Menu has the same problem
struct swiftuiTestApp: App {
@State private var val = false;
var body: some Scene {
WindowGroup {
Menu("menu") {
Toggle(isOn: $val) {
Text("open")
}.onChange(of: val) { oldValue, newValue in
print("onChange", newValue)
}
}
}
}
}
if I move onChange to Menu, the problem disappeared
Menu("menu") {
Picker("value \(value)", selection: $value) {
Text("A").tag("a")
Text("B").tag("b")
Text("C").tag("c")
}
.pickerStyle(.inline)
}
.onChange(of: value) { oldValue, newValue in
print("onChange", newValue)
}
but my goal is to encapsulate Picker into a controlled component similar to React, so I have to put state inside menu
import SwiftUI
struct TBSelect: View {
let title: String;
let value: String;
let options: Array<TBSelectOption>;
let tip: String;
let onChange: (_ value: String) -> Void;
@State private var innerValue: String;
struct TBSelectOption {
let title: String;
let value: String;
let systemImage: String?;
}
init(title: String, value: String, options: Array<TBSelectOption>, tip: String = "", onChange: @escaping (_ value: String) -> Void) {
_innerValue = State(initialValue: value);
self.title = title
self.value = value
self.options = options
self.tip = tip
self.onChange = onChange;
}
var body: some View {
Picker(title, selection: $innerValue) {
ForEach(options, id: \.value) { option in
if let systemImage = option.systemImage {
Label(option.title, systemImage: systemImage)
.tag(option.value)
} else {
Text(option.title)
.tag(option.value)
}
}
}
.help(tip)
.onChange(of: innerValue) { oldValue, newValue in
onChange(newValue)
}
}
}
I displayed the value on Picker title, it turns out that first time select another option , the value did changed, but the onChange is not trigger
Picker("value \(value)", selection: $value) {
//...
}
Having the same problem on iOS 17.4
with iOS 18 public beta and macOS 14.4.1, it works again. with no code change......
@FPST
I tried with catch
do {
self.modelContainer = try ModelContainer(for: Document.self, CheckPoint.self, configurations: self.modelConfiguration)
} catch let error {
print(error);
fatalError()
}
I can't find any clues with the error message

SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer)
on MacOS 14.5, the app on Mac also crash with the same error
Unresolved error loading container Error Domain=NSCocoaErrorDomain Code=134060 "A Core Data error occurred." UserInfo={NSLocalizedFailureReason=Unable to find a configuration named 'default' in the specified managed object model.}
I think there is something todo with MacOS 14.5 and iOS 17.5.....
the crash is on last line when create ModelContainer
