AutoCompleteTextField and Firebase - ios

Question

I am trying to integrate Firebase and AutoCompleteTextField in Swift so that I have autocomplete in the textField. I'm having a problem trying to turn the dictionary into an array so that I can set it in autoCompleteTextField.autoCompleteStrings. This is the code I have for it.
func handleTextFieldInterfaces() {
let ref = FIRDatabase.database().reference().child("Airport")
ref.observeEventType(.Value, withBlock: { (snapshot) in
self.autoCompleteTextField.onTextChange = {[weak self] text in
if !text.isEmpty {
var fbosStuff = [String]()
if let snaps = snapshot.value as? [[String: AnyObject]] {
for places in snaps {
print(places)
let names = places["code"] as? String
fbosStuff.append(names!)
}
self!.autoCompleteTextField.autoCompleteStrings = fbosStuff
}
}
}
})
}
and the response from Firebase that I am trying to put into the textfield is.
Snap (Airport) {
"Long Beach" = {
FBOs = {
Atlantic = {
100LL = "7.0";
freq = "120.1";
fullname = "Atlantic, Long Beach, KLGB";
"jet-A" = "5.5";
"phone number" = "[phone]";
};
Signature = {
100ll = "7.0";
email = "lgb#signatureflight.com";
freq = "120.1";
fullname = "Signature, Long Beach, KLGB";
"jet-a" = "5.5";
phonenumber = "[phone]";
};
};
code = KLGB;
fieldname = Daughtery;
location = "Long Beach, California, USA";
};
"Santa Monica" = {
FBOs = {
"American Flyers" = {
100ll = "5.38";
freq = "123.3";
fullname = "American Flyers, Santa Monica, KSMO";
phonenumber = "[phone]";
};
Atlantic = {
100ll = "7.79";
freq = "122.95";
fullname = "Atlantic, Santa Monica, KSMO";
"jet-a" = "7.19";
phonenumber = "[phone]";
};
};
code = KSMO;
fieldname = "Santa Monica Muni Airport";
location = "Santa Monica, California, USA";
};
}

Answer 1

Try :-
Swift 2
for places in snaps {
print(places.0) // Will give you the key
let names = places["code"] as? String
fbosStuff.append(names!)
}
Swift 3
for places in snaps {
print(places.key) // Will give you the key
let names = places["code"] as? String
fbosStuff.append(names!)
}
