33. Built on NSOperation Storyboards UITableView CocoaPods Vibrancy / Blur Dynamic Type Custom UIViewController Containment Local Push Notifications Fastlane Pantry Swift 3 Universal app
 (split view) Fabric / Crashlytics R.swift Buddybuild
34. NSOperations class BaseOperation : Operation { override var isAsynchronous: Bool { return true } 
 private var _executing = false { willSet { willChangeValue(forKey: "isExecuting") } didSet { didChangeValue(forKey: "isExecuting") } } override var isExecuting: Bool { return _executing } private var _finished = false { willSet { willChangeValue(forKey: "isFinished") } didSet { didChangeValue(forKey: "isFinished") } } override var isFinished: Bool { return _finished } class BaseOperation : Operation { func execute() { fatalError("You must override this") } func finish() { _executing = false _finished = true } }
35. NSOperations class FetchIssuesOperation : BaseOperation { let location: UserLocation? init(location: UserLocation?) { self.location = location }
 
 ... }
36. NSOperations override func execute() { let task = session.dataTask(with: url) { 
 (data, response, error) in if let e = error { print("Error fetching issues: \ (e.localizedDescription)”) } else { self.handleResponse(data: data, response: response) } self.finish() } task.resume() }
37. NSOperations self.issuesList = IssuesList(dictionary: json)
38. NSOperations func fetchIssues(completion: @escaping (IssuesLoadResult) -> Void) { let operation = FetchIssuesOperation(location: userLocation) operation.completionBlock = { [weak self, weak operation] in if let issuesList = operation?.issuesList { self?.issuesList = issuesList DispatchQueue.main.async { completion(.success) } } else {
 // …
 }
 
 } OperationQueue.main.addOperation(operation) }
39. NSOperations FetchIssuesOperation FetchStatsOperation ReportOutcomeOperation
40. NSOperations Composable Dependencies Cancellable Control Concurrency Quality of Service

42. Dynamic Type Dynamic Type Dynamic Type
43. Using a custom font made this more difficult
46. Getting Dynamic Type to work with UITableViewCells Define height with constraints
47. Getting Dynamic Type to work with UITableViewCells
48. Respond to Dynamic Type Changes UIContentSizeCategoryDidChangeNotification adjustsFontsForContentSizeCategory iOS 10.0
50. Getting dynamic fonts in code headline.font = UIFont.preferredFont( forTextStyle: UIFontTextStyleHeadline) subhead.font = UIFont.preferredFont( forTextStyle: UIFontTextStyleSubheadline) body.font = UIFont.preferredFont( forTextStyle: UIFontTextStyleBody)
51. https://github.com/nickoneill/Pantry if let available: Bool = Pantry.unpack("promptAvailable") { completion(available: available) } else { anExpensiveOperationToDetermineAvailability({ (available) -> () in Pantry.pack(available, key: "promptAvailable", expires: .Seconds(60 * 10)) completion(available: available) }) }
52. var autopersist: String? { set { if let newValue = newValue { Pantry.pack(newValue, key: "autopersist") } } get { return Pantry.unpack("autopersist") } } ...later... autopersist = "Hello!" // restart app, reboot phone, etc print(autopersist) // Hello!
