Converting Firebase data into Swift array - swift

Question

This is how my Firebase data looks like:
[ {
"adress" : "Högåsstigen 10 332 33 Gislaved",
"helg" : "18:00-02:00",
"latitude" : 57.2985,
"longitude" : 13.54326,
"namn" : "Restaurang Åsen",
"outlet" : 0,
"phone" : "0371-123456",
"star" : 0,
"tag" : "Restaurang",
"vardag" : "10:00-19:30"
}, {
"adress" : "Högåsstigen 12 332 33 Gislaved",
"helg" : "18:00-02:00",
"latitude" : 57.9985,
"longitude" : 13.94326,
"namn" : "Kalles ställe",
"outlet" : 0,
"phone" : "0371-123456",
"star" : 2,
"tag" : "Restaurang",
"vardag" : "10:00-19:30"
}, {
"adress" : "Högåsstigen 15 332 33 Gislaved",
"helg" : "18:00-02:00",
"latitude" : 55.603384,
"longitude" : 13.020619,
"namn" : "Olles Pub",
"outlet" : 0,
"phone" : "0371-123456",
"star" : 1,
"tag" : "Krog",
"vardag" : "10:00-19:30"
} ]
I want to grab "adress" from the database.
I'm having problem to convert the data I grab from Firebase to append into an array so I can use them later. I get the error "Value of type 'String' has no member 'generator'".
I have no idea how to proceed in my coding, any suggestions?
var adresserArray = [String]()
let ref = Firebase(url: "https://HIDINGMYURL.firebaseio.com/")
ref.observeEventType(.ChildAdded, withBlock: {snapshot in
let adresser = (snapshot.value.objectForKey("adress")) as! String!
for add in adresser{
adresserArray.append(adresser)
}
})

You are trying to iterate over String here
let adresser = (snapshot.value.objectForKey("adress")) as! String!
for add in adresser{
adresserArray.append(adresser)
}
try just replace this code with
let adresser = (snapshot.value.objectForKey("adress")) as! String
adresserArray.append(adresser)
