No idea why this error occurred, and I suspect that it's me putting initialization in the wrong place.
struct TodosDocument: FileDocument {
var todo: Context
@AppStorage("defaultText")
var defaultText: String = defaultContent
var content: String
var erroreousFileContent: Bool = false
init(content: String = defaultContent, defaultText: String = defaultContent) {
self.defaultText = defaultText
self.content = content
do {
self.todo = try JSONDecoder().decode(Context.self, from: content.data(using: .utf8)!)
} catch {
print("ERROR \(error)")
fatalError()
}
}
static var readableContentTypes: [UTType] { [.TodoType] }
init(configuration: ReadConfiguration) throws {
guard let data = configuration.file.regularFileContents,
let string = String(data: data, encoding: .utf8)
else {
throw CocoaError(.fileReadCorruptFile)
}
self.content = string
do {
self.todo = try JSONDecoder().decode(Context.self, from: data)
} catch {
self.todo = try JSONDecoder().decode(Context.self, from: defaultText.data(using: .utf8)!) // <- here
}
}
func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper {
let data = content.data(using: .utf8)!
let i = JSONEncoder()
i.outputFormatting = .prettyPrinted
let content = Context(title: todo.title, items: todo.items)
do {
let dat = try i.encode(content)
return .init(regularFileWithContents: dat)
} catch {
fatalError("Cannot write content \"\(data)\" with \(configuration): \(error)")
}
}
}
You should initialise todo first.
For instance, in its declaration (You do not show what Context is, so I guess), something like:
var todo: Context = Context() // <<--
Or you could do it in init
init(configuration: ReadConfiguration) throws {
guard let data = configuration.file.regularFileContents,
let string = String(data: data, encoding: .utf8)
else {
throw CocoaError(.fileReadCorruptFile)
}
self.content = string
self.todo = Context() // <<--
