Setup ViewController

From the Project Navigation Panel, navigate to {App Name} -> {App Name} -> ViewController and open ViewController.swift
>Note: The App Name is based on the name given when starting the project.
Find the import code at the top, and add the import section code below the other import lines.
Within the main ViewController class, modify or replace the viewDidLoad function with the viewDidLoad code below.
Note: Change the Api Key, center, zoom, and language to match your needs.

Import Section

import Mapbox


	override func viewDidLoad() {
        // Do any additional setup after loading the view.
        let apiKey = "Your Api Key"
        let center = CLLocationCoordinate2D(latitude: 37.78, longitude: -122.43)
        let startZoom = 12.0
        let mapLanguage = "en"
        let mapStyle = "slpy-mgl-style.json"
        let mapStyleUrl = URL(string: "\(mapStyle)?key=\(apiKey)&lang=\(mapLanguage")
        let mapView = MGLMapView(frame: view.bounds, styleURL: mapStyleUrl)
        mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        mapView.setCenter(center, zoomLevel: startZoom, direction: 0, animated: false)
        mapView.logoView.isHidden = true
        mapView.delegate = self
