This is my code before moving to Swift 3:
ref.observeEventType(.ChildAdded, withBlock: { snapshot in
let currentData = snapshot.value!.objectForKey("Dogs")
if currentData != nil {
let mylat = (currentData!["latitude"])! as! [String]
let mylat2 = Double((mylat[0]))
let mylon = (currentData!["longitude"])! as! [String]
let mylon2 = Double((mylon[0]))
let userid = (currentData!["User"])! as! [String]
let userid2 = userid[0]
let otherloc = CLLocation(latitude: mylat2!, longitude: mylon2!)
self.distanceBetweenTwoLocations(self.currentLocation, destination: otherloc, userid: userid2)
}
})
ref.observe(.childAdded, with: { snapshot in
let currentData = (snapshot.value! as AnyObject).object("Dogs")
if currentData != nil {
let mylat = (currentData!["latitude"])! as! [String]
let mylat2 = Double((mylat[0]))
let mylon = (currentData!["longitude"])! as! [String]
let mylon2 = Double((mylon[0]))
let userid = (currentData!["User"])! as! [String]
let userid2 = userid[0]
let otherloc = CLLocation(latitude: mylat2!, longitude: mylon2!)
self.distanceBetweenTwoLocations(self.currentLocation, destination: otherloc, userid: userid2)
}
})
Cannot call value of non-function type 'Any?!'
snapshot.value as! [String:AnyObject]
distanceBetweenTwoLocations
See the issue is that when you are instancing and initialising your variable you are telling it that the value its gonna receive will be a value
for the object named Dogs
present in this snapshot whose type is AnyObject
.
But snapshot.value
is of type Dictionary i.e [String:AnyObject]
,NSDictionary
..
And the Dogs
node that you retrieve is of type, either Dictionary or an Array.
Basically you should avoid to store a value in a variable, of type AnyObject
Try this:-
FIRDatabase.database().reference().child("Posts").child("post1").observe(.childAdded, with: { snapshot in
if let currentData = (snapshot.value! as! NSDictionary).object(forKey: "Dogs") as? [String:AnyObject]{
let mylat = (currentData["latitude"])! as! [String]
let mylat2 = Double((mylat[0]))
let mylon = (currentData["longitude"])! as! [String]
let mylon2 = Double((mylon[0]))
let userid = (currentData["User"])! as! [String]
let userid2 = userid[0]
let otherloc = CLLocation(latitude: mylat2!, longitude: mylon2!)
self.distanceBetweenTwoLocations(self.currentLocation, destination: otherloc, userid: userid2)
}
})
PS:- Seeing your JSON structure you might wanna convert it into a Dictionary not a Array
