Hi
Given a simple multiplatform app about Mushrooms, stored in SwiftData, hosted in iCloud using a TextEditor
@Model
final class Champignon: Codable {
var nom: String = ""
../..
@Attribute(.externalStorage)
var attributedStringData: Data = Data()
var attributedString: AttributedString {
get {
do {
return try JSONDecoder().decode(AttributedString.self,
from: attributedStringData)
} catch {
return AttributedString("Failed to decode AttributedString: \(error)")
}
}
set {
do {
self.attributedStringData = try JSONEncoder().encode(newValue)
} catch {
print("Failed to encode AttributedString: \(error)")
}
}
}
../..
Computed attributedString is used in a TextEditor
private var textEditorView: some View {
Section {
TextEditor(text: $model.attributedString)
} header: {
HStack {
Text("TextEditor".localizedUppercase)
.foregroundStyle(.secondary)
Spacer()
}
}
}
Plain Text encode, decode and sync like a charm through iOS and macOS
Use of "FontAttributes" (Bold, Italic, …) works the same
But use of "ForegroundColorAttributes" trigger an error :
Failed to decode AttributedString: dataCorrupted(Swift.DecodingError.Context(codingPath: [_CodingKey(stringValue: "Index 3", intValue: 3), AttributeKey(stringValue: "SwiftUI.ForegroundColor", intValue: nil), CodableBoxCodingKeys(stringValue: "value", intValue: 1)], debugDescription: "Platform color is not available on this platform", underlyingError: nil))
Is there a way to encode/decode attributedString data platform conditionally ?
Or another approach ?
Thanks for advices

Done this model:
@Model
public final class Category: Codable {
var nom: String = ""
@Relationship(deleteRule: .cascade, inverse: \Property.category)
var properties: [Property]?
}
How to create #predicate to search text in like…
let predicate = #Predicate<Category> { category in
searchText.isEmpty || category.nom.localizedStandardContains(searchText) ||
category.properties.contains {
$0.nom.localizedStandardContains(searchText)
}
}
without this error:
SQLCore dispatchRequest: exception handling request: <NSSQLCountRequestContext: 0x6000038dc620>, to-many key not allowed here with userInfo of (null)
