I currently have a Firestore database reference that queries the data trying to find a user with a certain username. After I get the user I want to try to login. However, I have noticed that the block of code to query for a user, returns as soon as it is called. Is there any way to add a completion block or at least stop the program until it is done querying.
u.name = name
global.db.collection("users").whereField("username", isEqualTo: u.name).getDocuments(completion: { (snap, error) in
if error != nil {
print(error?.localizedDescription as Any)
return
}
for doc in (snap?.documents)! {
u.email = doc.data()["email"] as! String
}
})
Auth.auth().signIn(withEmail: u.email, password: password, completion: { (user, error) in
if error != nil {
print(error?.localizedDescription as Any)
return
}
print("Succesfully Logged In")
self.toListSelector(user: u)
})

You need to put your signIn
INSIDE the getDocuments
handler, probably after the for
loop?
