I have checked this code until I am 'blue in the face', but I can't see why I get an error saying missing closing bracket. // //  ExploreDataManager.swift //  LetsEat3 // //  Created by Tony Hudson on 16/04/2021. // import Foundation class ExploreDataManager {     func  fetch() {         for data in loadData() {         print(data)     } }     fileprivate func loadData() - [[String: AnyObject]] {         guard let path = Bundle.main.path(forResource: "ExploreData", ofType: "plist"), let items = NSArray(contentsOfFile: path) else  {             return [[:]]         }         return items as![[String: AnyObject]]     } } If I add an additional bracket it then reports an additional 'Expected '}' in class? I have counted 5 opening brackets and 5 closing brackets. I even checked to see whether I had mistakenly typed the wrong type of bracket elsewhere in the code! Is this a bug? If not what is the reason. for this error?

I am learning Xcode from Ahmad Sahar's book and somehow I have disconnected the exploreViewController from the navigation controller. I have now progressed far beyond the point where this was connected to the navigation controller, so I Ctrl + Dragged from the button to the navigation controller. However when I ran the project I get a Compile error: Couldn't compile connection: IBCocoaTouchOutletConnection: 0x123ef3a50 (sN1-9E-uLq)  source=IBProxyObject: 0x123ef2be0 (Wnw-oV-gaS) 'Placeholder for UIStoryboardPopoverPresentationSegueTemplate with OID GlU-yO-pRa'  property=anchorView  destination=IBUIButton: 0x120195400 (WOO-Ms-Zlt) 'Button' As I am still learning I am not sure how to fix this problem? If I click on the segue icon it says 'Present as Popover segue' and Segue Actions shows 'instantiation' with a circle but if I click on the circle nothing is listed for the segue. Please help?

I am trying to learn Xcode using iOS 14 Programming for Beginners (Packt Pub). I am now working on the part that adds the pins to the MapView, but when I run the app the map button is unresponsive (Runtime error). I get the following message in the Debug area: __2021-07-25 16:08:23.919240+0100 EatOut[1420:21167] Metal API Validation Enabled Could not cast value of type 'Swift.Array<EatOut.RestaurantItem>' (0x1c31e3588) to '__C.MKAnnotation' (0x1c31e3888). 2021-07-25 16:08:24.003987+0100 EatOut[1420:21167] Could not cast value of type 'Swift.Array<EatOut.RestaurantItem>' (0x1c31e3588) to '__C.MKAnnotation' (0x1c31e3888).

The runtime error is in this func, in the final line:  func addMap(_ annontations: [RestaurantItem]) {             mapView.setRegion(manager.currentRegion(latDelta: 0.5, longDelta: 0.5), animated: true)             mapView.addAnnotation(manager.annotations as! MKAnnotation) I get a build error on the final line if I do not apply the fix, which adds the as! MKAnnotation. Is the error in the .plist or does the code need altering? Please can you help? Here is the full code for the swift file: //  MapViewController.swift //  EatOut // //  Created by Tony Hudson on 15/07/2021. // import UIKit import MapKit class MapViewController: UIViewController, MKMapViewDelegate {     let manager = MapDataManager()     var selectedRestaurant: RestaurantItem?     @IBOutlet weak var mapView: MKMapView!     override func viewDidLoad() {         initialise()         func initialise() {             manager.fetch { (annotations) in addMap(annotations)             }         }         func addMap(_ annontations: [RestaurantItem]) {             mapView.setRegion(manager.currentRegion(latDelta: 0.5, longDelta: 0.5), animated: true)             mapView.addAnnotation(manager.annotations as! MKAnnotation)         }     } }

I am trying to learn Xcode using iOS 14 Programming for Beginners (Packt Pub). I have had several problems with the code so I have been ultra careful and I can't find any mistakes. There is also another error in the code in an extension in the code. Here is a copy of the code: / //  MapViewController.swift //  EatOut // //  Created by Tony Hudson on 15/07/2021. // Links to: Item -308,318,319,320,321,324,341,352,353 import UIKit import MapKit class MapViewController: UIViewController,MKMapViewDelegate {     @IBOutlet weak var mapView: MKMapView!     let manager = MapDataManager()     var selectedRestaurant: RestaurantItem?     override func viewDidLoad() {         super.viewDidLoad()         initialize()     }     override func prepare(for segue: UIStoryboardSegue, sender: Any?){         switch segue.indentifier! { //<<Value of type 'UIStoryboardSegue' has no member 'indentifier'         case Segue.showDetail.rawValue: showRestaurantDetail(segue: segue)         default:             print("Segue not added")         }     } } // MARK: Private Extension private extension MapViewController {     func initialize() {         mapView.delegate = self         manager.fetch {(annotations) in addMap(annotations)}     }     func addMap(_ annotations: [RestaurantItem]) {         mapView.setRegion(manager.currentRegion(latDelta: 0.5, longDelta: 0.5), animated: true)         mapView.addAnnotations(manager.annotations)     }     func showRestaurantDetail (segue: UIStoryboardSegue){         if let viewController = segue.destination as?

Can anyone help?

I am trying to learn Xcode using a book called 'iOS 14 Programming for Beginners'. Although the book is supposed to show the correct code I have found that it still raises errors when I type in the code. They also have the code online, which I have downloaded and compared to my code, yet I still get errors. Here is the file that produces the errors: // //  ExploreViewController.swift //  EatOut // //  Created by Tony Hudson on 15/07/2021 // import UIKit class ExploreViewController: UIViewController, UICollectionViewDelegate {     @IBOutlet weak var collectionView: UICollectionView!     let manager = ExploreDataManager()     var selectedCity: LocationItem?     var headerView: ExploreHeaderView!     override func viewDidLoad() {         super.viewDidLoad()         initialize()     }     override func prepare(for segue: UIStoryboardSegue, sender: Any?) {         switch segue.identifier {         case Segue.locationList.rawValue: showLocationList(segue: segue)         case Segue.restaurantList.rawValue:   //ERROR HERE showRestaurantListing(segue: segue)         default:             print("Segue not added")         }     }     override func shouldPerformSegue(withIdentifier identifier: String, sender: Any?) -> Bool {         if identifier == Segue.restaurantList.rawValue { //AND HERE             guard selectedCity!= nil else { showAlert()               return false             }             return true       }         return true     } } // MARK: Private Extension private extension ExploreViewController {     func initialize() {         manager.fetch()     }     func showLocationList(segue: UIStoryboardSegue) {         guard let navController = segue.destination as?
