This morning I wanted to continue working on my project, but XCode suddenly showed me a lot of errors. They were absolutely silly errors, like Image doesn't have .resizable modifier e.t.c.
Then I started a new project to make sure my project is OK, and yes, XCode was full of errors even in its starting project. I attached the screenshot of the phenomenon.
What I tried so far:
Clean build folder
Quit and restart XCode
I used DevCleaner
Restart machine
Uninstall and reinstall XCode
to no avail.
Do you have any ides? Thanks.

I have a list of rows of articles in a SwiftUI List. The code is the following:
struct ArticleListView: View {
var articles: [Article]
var body: some View {
List {
ForEach(articles) { a in
ArticleRow(article: a)
}
}
}
}
When I run it in the simulator it works like a charm but the Preview Canvas always returns with an error.
The Article struct conforms to Identifiable so this is not really the problem.
I have tried to play a little with the view. When I replaced the ForEach with the following:
List {
ForEach(1..<5) { i in
ArticleRow(article: articles[i])
}
}
the preview displayed the list beautifully.
But when I replaced the ForEach with the indices, like this:
List {
ForEach(articles.indices, id:\.self) { i in
ArticleRow(article: articles[i])
}
}
the Preview canvas was not able to display the view.
The error message is the same for all scenarios:
MessageSendFailure: Message send failure for update
==================================
| MessageError: Connection interrupted
Does anybody have any idea how to solve this, or is this maybe a bug in the current (13.2 and 13.2.1) Xcode version?
Thank you.
I made a new project to figure out how List and editing List works and there was no problem at all, everything was going smoothly.
Then I transferred the code over into an existing project but I ran into an unusual problem: when I try to use custom button to change the EditMode and make List editable it does not work. However when I use the original EditButton the List goes into editing mode.
Do you have any ideas, why is this happening?
This is the code:
@Environment(\.editMode) var editMode
var body: some View {
VStack {
HStack {
Spacer()
EditButton()
.accentColor(.black)
Button(action: {
editMode?.wrappedValue = editMode?.wrappedValue == .active ? .inactive : .active
}) {
Text(editMode?.wrappedValue == .active ? "Saved" : "Modify")
}
}
.padding(.horizontal)
if emptyDictionary {
Divider()
Spacer()
Text("Nothing here yet")
.font(.light18)
Spacer()
} else {
List {
ForEach(keys, id:\.self) { color in
if !favourites(color: color).isEmpty {
Section(header: headerView(color: color)) {
ForEach(favourites(color: color)) { fav in
versRow(vers: fav, color: color)
}
.onDelete(perform: {indexSet in
store.deleteFavourites(color: color, indexSet: indexSet)
})
.onMove { (indexSet, newOffset) in
store.moveFavourites(color: color, indexSet: indexSet, newOffset: newOffset)
}
}
}
}
}
.padding(.horizontal)
}
}
}
The thing is the editMode environment variable changes with every click because the text in the custom button changes accordingly but the List does not go into editing mode. Strange.
