Smallest array from current location iOS Swift

The below function was used to return the smallest distance location arrays from Location you sent.
Also, the mutable array must have a model with lat, lang and distance values.

Code:
    func matchLocation(currentLocation:CLLocation,geoPlace:NSMutableArray) ->NSMutableArray {

        

        var smallestDistanceArray = NSMutableArray()

        

        for location in geoPlace {

            let tempLocation = location

            let markLocation:CLLocation = CLLocation(latitude: tempLocation.latitude, longitude: tempLocation.longitide)

            let distance = markLocation.distance(from: currentLocation)

            if  distance < Double(tempLocation.distance) {

                smallestDistanceArray.add(tempLocation)

            }

        }

        return smallestDistanceArray

    }
