Answer 1

Okay I've found an solution. I basically called the function at the end of the first one.

So basically:

    var searchLocation = String()
    var searchLocationCoordinates = [String:Double]()
    var searchRange = Int()


    override func viewDidLoad() {
        super.viewDidLoad()

        // Gets the user's search preference
        getTheSearchLocationAndRange()
    }

    func getTheSearchLocationAndRange() {
    // Code for getTheSearchLocationAndRange()

    loadDataFromDatabase()
    }

    func loadDataFromDatabase(){
    // Code for loadDataFromDatabase()
    }
