I have an App and also a Share Extension. Between them I share data via UserDefaults. But it stopped working all of a sudden. Only bools or Strings can now be retrieved inside the Share Extension but when trying to retrieve a Custom Struct it is always returning nil.
Custom Struct getter/setter in UserDefaults:
//MARK: dataSourceArray
func setDataSourceArray(data: [Wishlist]?){
set(try? PropertyListEncoder().encode(data), forKey: Keys.dataSourceKey)
synchronize()
}
func getDataSourceArray() -> [Wishlist]? {
if let data = self.value(forKey: Keys.dataSourceKey) as? Data {
do {
_ = try PropertyListDecoder().decode(Array < Wishlist > .self, from: data) as [Wishlist]
} catch let error {
print(error)
}
if let dataSourceArray =
try? PropertyListDecoder().decode(Array < Wishlist > .self, from: data) as[Wishlist] {
return dataSourceArray
}
}
return nil
}
I am calling it like this inside my Extension as well as in my Main App:
if let defaults = UserDefaults(suiteName: UserDefaults.Keys.groupKey) {
if let data = defaults.getDataSourceArray() {
print("working")
} else {
print("error getting datasourceArray")
}
}
This is printing "working" in the Main App but "error getting datasourceArray" in my Extension. I don't understand the issue, especially because simple Bool-Getter are working also from my Share Extension, the issue is only with the Custom Struct.
What am I missing here?
Wishlist Struct:
import UIKit
enum PublicState: String, Codable {
case PUBLIC
case PUBLIC_FOR_FRIENDS
case NOT_PUBLIC
}
struct Wishlist: Codable {
var id: String
var name: String
var image: UIImage
var wishes: [Wish]
var color: UIColor
var textColor: UIColor
var index: Int
var publicSate: PublicState
enum CodingKeys: String, CodingKey {
case id, name, image, wishData, color, textColor, index, isPublic, isPublicForFriends, publicSate
}
init(id: String, name: String, image: UIImage, wishes: [Wish], color: UIColor, textColor: UIColor, index: Int, publicSate: PublicState) {
self.id = id
self.name = name
self.image = image
self.wishes = wishes
self.color = color
self.textColor = textColor
self.index = index
self.publicSate = publicSate
}
init(from decoder: Decoder) throws {
let values = try decoder.container(keyedBy: CodingKeys.self)
id = try values.decode(String.self, forKey: .id)
name = try values.decode(String.self, forKey: .name)
wishes = try values.decode([Wish].self, forKey: .wishData)
color = try values.decode(Color.self, forKey: .color).uiColor
textColor = try values.decode(Color.self, forKey: .textColor).uiColor
index = try values.decode(Int.self, forKey: .index)
publicSate = try values.decode(PublicState.self, forKey: .publicSate)
let data = try values.decode(Data.self, forKey: .image)
guard let image = UIImage(data: data) else {
throw DecodingError.dataCorruptedError(forKey: .image, in: values, debugDescription: "Invalid image data")
}
self.image = image
}
func encode(to encoder: Encoder) throws {
var container = encoder.container(keyedBy: CodingKeys.self)
try container.encode(id, forKey: .id)
try container.encode(name, forKey: .name)
try container.encode(wishes, forKey: .wishData)
try container.encode(Color(uiColor: color), forKey: .color)
try container.encode(Color(uiColor: textColor), forKey: .textColor)
try container.encode(index, forKey: .index)
try container.encode(image.pngData(), forKey: .image)
try container.encode(publicSate, forKey: .publicSate)
}
}
Update
This is the part where it fails:
if let data = self.value(forKey: Keys.dataSourceKey) as? Data
Is there any way to catch an error?
I also found out that this feature is actually working for other users. The app is live: https://apps.apple.com/de/app/wishlists-einfach-w%C3%BCnschen/id1503912334
But it is not working for me? I deinstalled the app, downloaded it from the App Store but it is still not working.
