I want to add a value to Firestore. When finished I want to return the added value. The value does get added to Firestore successfully. However, the value does not go through sink.
This is the function that does not work:
func createPremium(user id: String, isPremium: Bool) -> AnyPublisher<Bool,Never> {
let dic = ["premium":isPremium]
return Future<Bool,Never> { promise in
self.db.collection(self.dbName).document(id).setData(dic, merge: true) { error in
if let error = error {
print(error.localizedDescription)
} else {
/// does get called
promise(.success(isPremium))
}
}
}.eraseToAnyPublisher()
}
I made a test function that works:
func test() -> AnyPublisher<Bool,Never> {
return Future<Bool,Never> { promise in
promise(.success(true))
}.eraseToAnyPublisher()
}
premiumRepository.createPremium(user: userID ?? "1234", isPremium: true)
.sink { receivedValue in
/// does not get called
print(receivedValue)
}.cancel()
test()
.sink { recievedValue in
/// does get called
print("Test", recievedValue)
}.cancel()
Also I have a similar code snippet that works:
func loadExercises(category: Category) -> AnyPublisher<[Exercise], Error> {
let document = store.collection(category.rawValue)
return Future<[Exercise], Error> { promise in
document.getDocuments { documents, error in
if let error = error {
promise(.failure(error))
} else if let documents = documents {
var exercises = [Exercise]()
for document in documents.documents {
do {
let decoded = try FirestoreDecoder().decode(Exercise.self, from: document.data())
exercises.append(decoded)
} catch let error {
promise(.failure(error))
}
}
promise(.success(exercises))
}
}
}.eraseToAnyPublisher()
}
I tried to add a buffer but it did not lead to success.
