Retrieving a Boolean array from a snapshot from Firebase gives me 0's and 1's. What is the best way to store an Boolean array from Firebase to an array in my project?
This is my code:
func loadUpInformation()
{
print("loading data")
let user = FIRAuth.auth()?.currentUser
let userID = FIRAuth.auth()?.currentUser?.uid
ref = FIRDatabase.database().reference()
ref.child("users").child(userID!).observeSingleEvent(of: .value, with: { (snapshot) in
if !snapshot.exists() { return }
if let achievementsUnlockedFirebase = snapshot.childSnapshot(forPath: "/AchievementsUnlocked").value
{
// ????
}
})
}
I already tried:
Read Data from Firebase and Save Into an Array (Swift)
if let AchievementsUnlockedFirebase = snapshot.childSnapshot(forPath: "/AchievementsUnlocked").value as? Bool
{
print("snapshot exist")
achievementsUnlocked.append(AchievementsUnlockedFirebase)
print(AchievementsUnlockedFirebase)
print(achievementsUnlocked)
}
doesn't give me a print, changing as? String to as? Bool has the same result. Removing the "as? String" gives me an output, these are the 0's and 1's. Therefore I could use as? Int but then I need to convert it to Booleans. I tried it with a for in loop, but then I get the error cannot convert type to Sequence.
How can I convert a Boolean array in Firebase to a Boolean array in Swift?
