List(am.students) { item in
HStack {
Text(item.name).font(fancyFont)
Spacer()
Button(item.casual ? "All Paid" : "Reverse All Paid") {
// Issue: pressing this button also results in Remove button action being invoked.
item.casual = !item.casual
}.foregroundColor(Color(white: 0.15))
.padding(3)
.overlay(
RoundedRectangle(cornerRadius: 5)
.stroke(Color(white: 0.5), lineWidth: 3)
)
Spacer().frame(width: 40)
Button("Remove") {
Task {
await am.delete(student: item)
}
}.foregroundColor(Color(white: 0.15))
.frame(width: 80)
.padding(3)
.overlay(
RoundedRectangle(cornerRadius: 5)
.stroke(Color(white: 0.5), lineWidth: 3)
)
}
}
When "All Paid" button is pressed, the "Remove" button action also executes.
At a guess, the list row executes everything?

A class which holds a list of spells.
@MainActor
class ListOfSpells : ObservableObject {
@Published var allSpells : [String] = []
@Published var currSpell : SpellInfo
@Published var spell : String = "" {
didSet {
Task {
if let spl = await DBAccess.instance.GetSpellInfo(spell: self.spell) {
currSpell = SpellInfo(info: spl)
}
else {
currSpell = SpellInfo(info: dummySpellField)
}
}
}
}
@Published var filterString = ""
init() {
currSpell = SpellInfo(info: dummySpellField)
Task {
do {
allSpells = try await DBAccess.instance.GetAllNames(force: false)
}
catch let E {
print(E.localizedDescription)
}
}
}
}
SwiftUI file
@Model
final class ThemeSpell {
var spell : String
init(spell S: String) {
spell = S
}
}
struct ContentView: View {
@Environment(\.modelContext) private var modelContext
@StateObject var spells = ListOfSpells()
@Query private var themeSpells : [ThemeSpell]
var body: some View {
HStack {
List(selection: $spells.spell) { **
//List { **
ForEach(spells.allSpells, id: \.self) { spell in
Text(spell)
}
}.frame(width: 240)
Spacer()
VStack {
//SpellUIView(spell: spells)
HStack {
Button(">>>") {
addItem(name: spells.spell)
}
.frame(width: 80)
.keyboardShortcut(.space, modifiers: [.option])
}
}
.frame(height: 600)
Spacer()
List {
ForEach(themeSpells) { item in
Text(item.spell) ***
}
}.frame(width: 240)
}
}
private func addItem(name: String) {
let newItem = ThemeSpell(spell: name)
modelContext.insert(newItem)
}
}
** commenting out selection:$spells.spell makes no difference.
*** if this is left in, the app crashes with the following exception:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.'
Can't post entire stack trace. Too big. But the exception is raised a background thread.

My SwiftUI code is a modification of the standard code created with New Project.
The standard code uses a toolbarItem '+' to create a new item.
My code uses a list of strings to which can be added to the model.
This is for macOS.
How do you create a new window via a dialog that REQUIRES user input to proceed on SwiftUI?
New > Open Dialog > User Entry/Select > Window displays.
Or do I have to use AppKit and xibs?

I have a macOS app which uses an embedded SQLite DB.
For some reason when I quit the app, a OK/Cancel dialog appears with this warning: 'Startup errors may overwrite unloaded queries. Do you wish to overwrite the query database?'.
Anyone have any idea why this is occurring. It only started ~15mins before this post was created. I only ever read from the DB, never written.
Google search comes up with nothing.
Ventura 13.3. Xcode Version 14.3 (14E222b). Deployment target 10.15. Cocoa app.
I have written a dance studio booking app for my brother in which he records name, email and phone number.
The information is for his use only and it won't be accessed by 3rd parties. It will be stored on iCloud and OneDrive but no one else has access.
Do I need to declare 'Collected Data'?
I am writing an iOS app for ONE person.
It is for their use only.
Will the App store allow such an app?
Besides a passcode on use, is there any way to prevent others from using it?
I have a simple command line tool that requires a DB to function.
Where do I put the database file?
Application Support or some posix directory?
TIA

Annoying issue.
If I close my designated debug window, the entire project closes.
Only applies to this project and no other.
Closing other windows work as normal.
Closing debug window last changes nothing if I reopen the other windows. Closing the debug window closes the project.
I have deleted the 'Derived Data' folder.
Is there some obscure setting causing this?
TIA Mark
