Sorry, I see the screenshot doesn’t show much…
and the Xcode I am using is Version 8.2.1 (8C1002)
I know about that because I ran into that problem with the previous version of this book that I bought and could not complete the examples because of the version changes. So I have purposely not updated my Xcode until I finish this book.
Okay, So here is the code where I am having errors show up:
AppDelegate.swift - Shows an error on ItemsViewController as Use of undeclared type "ItemsViewController"
CODE>
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
//Create an ItemStore
let itemStore = ItemStore()
// Access the ItemsViewController and set its item store
let itemsController = window!.rootViewController as! ItemsViewController
itemsController.itemStore = itemStore
return true
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
}
ItemsViewController.swift - Shows two errors, ItemStore! has error as - undeclared type, and let cell = UITableViewCell(style: .value1, resuseIdentifier: “UITableViewCell”) has error as -= Argument labels (style: resuseIdentifier:) do not match any available overloads.
CODE>
import UIKit
class ItemsViewController: UITableViewController {
var itemStore: ItemStore!
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return itemStore.allItems.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Create an instance of UITableViewCel, with default appearance
let cell = UITableViewCell(style: .value1, resuseIdentifier: "UITableViewCell")
// Set the text on the cell with the description of the item
// that is at the nth index of items, where n = row this cell
// will appear in on the tableview
let item = itemStore.allItems[indexPath.row]
cell.textLabel?.text = item.name
cell.detailTextLabel?.text = "$](item.valueInDollars)"
return cell
}
}
