• Changing the size of a modal view controller

  Once, the user taps a button, I want my modalViewController to appear as a small square in the middle of the screen (where you can still see the original view controller in the background).

  Almost every answer on stackoverflow I find uses the storyboard to create a modal view controller, but I've gotten this far with everything I've found.

  When you tap the button that is supposed to bring up the modal view, this function is called:

  func didTapButton() {
      let modalViewController = ModalViewController()
      modalViewController.definesPresentationContext = true
      modalViewController.modalPresentationStyle = .overCurrentContext
      navigationController?.present(modalViewController, animated: true, completion: nil)
  }
  

  And the modalViewController contains:

  import UIKit
  
  class ModalViewController: UIViewController {
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          view.backgroundColor = .blue
          view.isOpaque = false
  
          self.preferredContentSize = CGSize(width: 100, height: 100)
  
      }
  
  }
  

  Based on the answers I found, I was under the impression that if I set preferredContentSize = CGSize(width: 100, height: 100), then it would make the modal view controller 100px x 100px.

  However, the view controller takes up the entire screen (except for the tab bar because I set modalViewController.modalPresentationStyle = .overCurrentContext

  I'm obviously missing a step here, but I want to do everything programmatically as I'm not using the Storyboard at all in my project (except for setting the opening controller)

  Thanks in advance for you help!!
• Stretchy Layout not working with child view controller

  I'm trying to follow the example described here for making a stretchy layout which includes a UIImageView and UIScrollView. https://github.com/TwoLivesLeft/StretchyLayout/tree/Step-6

  The only difference is that I replace the UILabel used in the example with the view of a child UIViewController which itself contains a UICollectionView. This is how my layout looks - the blue items are the UICollectionViewCell.

  This is my code:

  import UIKit
  import SnapKit
  
  class HomeController: UIViewController, UIScrollViewDelegate {
  
  private let scrollView = UIScrollView()
  private let imageView = UIImageView()
  private let contentContainer = UIView()
  private let collectionViewController = CollectionViewController()
  
  override var preferredStatusBarStyle: UIStatusBarStyle {
      return .lightContent
  }
  
  override func viewDidLoad() {
      super.viewDidLoad()
  
  
      scrollView.contentInsetAdjustmentBehavior = .never
      scrollView.delegate = self
  
      imageView.image = UIImage(named: "burger")
      imageView.contentMode = .scaleAspectFill
      imageView.clipsToBounds = true
  
      let imageContainer = UIView()
      imageContainer.backgroundColor = .darkGray
  
      contentContainer.backgroundColor = .clear
  
      let textBacking = UIView()
      textBacking.backgroundColor = #colorLiteral(red: 0.7450980544, green: 0.1235740449, blue: 0.2699040081, alpha: 1)
  
      view.addSubview(scrollView)
  
      scrollView.addSubview(imageContainer)
      scrollView.addSubview(textBacking)
      scrollView.addSubview(contentContainer)
      scrollView.addSubview(imageView)
  
      self.addChild(collectionViewController)
      contentContainer.addSubview(collectionViewController.view)
      collectionViewController.didMove(toParent: self)
  
  
      scrollView.snp.makeConstraints {
          make in
  
          make.edges.equalTo(view)
      }
  
      imageContainer.snp.makeConstraints {
          make in
  
          make.top.equalTo(scrollView)
          make.left.right.equalTo(view)
          make.height.equalTo(imageContainer.snp.width).multipliedBy(0.7)
      }
  
      imageView.snp.makeConstraints {
          make in
  
          make.left.right.equalTo(imageContainer)
  
          //** Note the priorities
          make.top.equalTo(view).priority(.high)
  
          //** We add a height constraint too
          make.height.greaterThanOrEqualTo(imageContainer.snp.height).priority(.required)
  
          //** And keep the bottom constraint
          make.bottom.equalTo(imageContainer.snp.bottom)
      }
  
      contentContainer.snp.makeConstraints {
          make in
  
          make.top.equalTo(imageContainer.snp.bottom)
          make.left.right.equalTo(view)
          make.bottom.equalTo(scrollView)
      }
  
      textBacking.snp.makeConstraints {
          make in
  
          make.left.right.equalTo(view)
          make.top.equalTo(contentContainer)
          make.bottom.equalTo(view)
      }
  
      collectionViewController.view.snp.makeConstraints {
          make in
  
          make.left.right.equalTo(view)
          make.top.equalTo(contentContainer)
          make.bottom.equalTo(view)
      }
  
  }
  
  override func viewDidLayoutSubviews() {
      super.viewDidLayoutSubviews()
  
      scrollView.scrollIndicatorInsets = view.safeAreaInsets
      scrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: view.safeAreaInsets.bottom, right: 0)
  }
  
  //MARK: - Scroll View Delegate
  
  private var previousStatusBarHidden = false
  
  func scrollViewDidScroll(_ scrollView: UIScrollView) {
      if previousStatusBarHidden != shouldHideStatusBar {
  
          UIView.animate(withDuration: 0.2, animations: {
              self.setNeedsStatusBarAppearanceUpdate()
          })
  
          previousStatusBarHidden = shouldHideStatusBar
      }
  }
  
  //MARK: - Status Bar Appearance
  
  override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation {
      return .slide
  }
  
  override var prefersStatusBarHidden: Bool {
      return shouldHideStatusBar
  }
  
  private var shouldHideStatusBar: Bool {
      let frame = contentContainer.convert(contentContainer.bounds, to: nil)
      return frame.minY < view.safeAreaInsets.top
  }
  
  }
  

  Everything is the same as in this file: https://github.com/TwoLivesLeft/StretchyLayout/blob/Step-6/StretchyLayouts/StretchyViewController.swift with the exception of the innerText being replaced by my CollectionViewController.

  As you can see, the UICollectionView is displayed properly - however I am unable to scroll up or down anymore. I'm not sure where my mistake is.
• Swift combine different type into one array to display data for UITableView

  I have tableview where I need to show few sections. You should imagine this table like a playlist of your songs. In the top first section I need to display a cell with button which will add more songs to the playlist and other sections of tableview are header titles of Music category (like pop, rock and etc). Each of these sections contains cells which are songs names.

  I have an array of songs called like this: var songsGroups = [SongGroup]. Which is actually my datasource.

  SongGroup contains few properties:

  var categoryName: String
  var songs: [Songs]
  

  But the problem appears on the next level. I every time need to check indexPath.section and do like this:

  if indexPath.section == 0 {
  // this is a section for ADD NEW SONG BUTTON cell no need in header title as there is no data repression only static text on the cell.
  } else {
  var musicCategoryName = songsGroups[indexPath.seciton - 1]. categoryName
  headerTitle.title = musicCategoryName
  }
  

  As you see my code became magical by adding this cool -1 magical number. Which I replay don't love at all.

  As an idea for sure I can try to combine my ADD NEW SONG BUTTON section (by adding some additional object) with songsGroups array and create NSArray for this purposes. Like in Objective-C as you remember. So then my datasource array will looks like this:

  some NSArray = ["empty data for first cell", songsGroups[0], songsGroups[1]... etc]
  

  So then there is no need to check any sections we can trust our array to build everything and even if I will add more empty data cells there is no need for me to handle my code via if block and adding tons of magical numbers.

  But the issue I see here that we don't use explicit types of array and it's upset.

  So maybe you know more beautiful solutions how to resolve my issue.
• Value not passing between viewControllers

  Struggling to get my viewControllers to send value from the main viewController to a second. I want it to happen on a button click, I'm going to get the value from the button and pass it to the new form. But it just isn't working.

  Code for main ViewController

  class ViewController: UIViewController {
  override func viewDidLoad() {
      super.viewDidLoad()
  }
  
  @IBAction func butClick(_ sender: UIButton) {
      NSLog("Button Pressed : %@",[sender .currentTitle])
      //var tt = [sender .currentTitle]
      // Create the view controller
      let vc = TimesTablesViewController(nibName: "TimesTablesViewController", bundle: nil)
      vc.passedValue = "xx"
      self.performSegue(withIdentifier: "pushSegue", sender: nil)
  
  }
  }
  

  Code for second viewController called TimesTablesViewController:

  class TimesTablesViewController: UIViewController {
  
  @IBOutlet weak var titleLabel: UILabel!
  
  var passedValue:String = ""
  
  override func viewDidLoad() {
      super.viewDidLoad()
      titleLabel?.text = "\(passedValue) Times Table"
  }
  
  }
  

  I've followed tutorials but can't seem to solve the problem! Thanks for any help!
• Observable.create inside generic Alamofire call function not working when calling validate()

  I want to make a validated network request using Alamofire, through a 'generic' function. If I don't use RX at all or if I don't call validate() or anyCustomValidate() it works fine, but if I use it with the Observable.create and validate() as below, it does not work. This is what it does instead:

       1.makes tokenRefresh call
       2.receives the new token
       3.calls completion(true, 0.0) (as below)
  

  but then nothing happens...

  Here is my generic function:

  func sendRequest<Response: Codable>(endpoint: URLRequestConvertible) -> Observable<Response> {
      return Observable<Response>.create { observer in
          let request = self.session.request(endpoint)
              .validate()
              .responseJSON { response in
                  print(response)
                  switch response.result {
                  case .success:
                      do {
                          let model = try JSONDecoder().decode(Response.self, from: response.data!)
                          observer.onNext(model)
                      } catch {
                          print("generic call function error: \(error)")
                          observer.onError(RequestError.failedParsingError(ErrTypes.somethingWrong.rawValue))
                      }
                  case .failure:
                  observer.onError(RequestError.failedParsingError(ErrTypes.somethingWrong.rawValue))
                  }
          }
          return Disposables.create {
              request.cancel()
          }
      }.observeOn(MainScheduler.instance)
  }
  

  This is how I use it to get a specific response:

  func getAddresses(clientId: Int) -> Observable<[AddressesResponse]> {
      return sendRequest(endpoint: CustomerEndPoint.getAddresses(userID: clientId))
  }
  

  And this is how I call the function:

   @objc func buttonPressed() {
      getAddresses(clientId: 1111).subscribe(onNext: { addresses in
          print(addresses)
      }).disposed(by: disposeBag)
  }
  

  This is my Request retrier:

  extension AuthHandler: RequestRetrier {
  
  func should(_ manager: SessionManager, retry request: Request, with error: Error, completion: @escaping RequestRetryCompletion) {
      guard let request = request as? DataRequest, request.delegate.data != nil else { fatalError() }
      guard let headerStatusCode = request.response?.statusCode else {
          completion(false, 0.0)
          return
      }
      if headerStatusCode == 401 || headerStatusCode == 403 {
          refreshToken(success: {
              completion(true, 0.0)
          }, failure: { message in
              print(message)
          })
      } else {
          if let json = String(data: request.delegate.data!, encoding: String.Encoding.utf8),
          let jsonObject = dictionaryWithJSONString(json) as? [String:Any],
          let statusMessage = jsonObject["statusMessage"] as? [String: Any],
          let status = statusMessage["status"] as? Int {
              if status == 401 || status == 403 {
                  self.refreshToken(success: {
                      completion(true, 0.0)
                  }, failure: { message in
                      completion(false, 0.0)
                      print(message)
                  })
              }
          }
      }
  }
  

  After a while this gets printed on the console log:

• Passing class by value

  I'm new to Swift so please let me know if I've missed something painful obvious. I have a class that I want to pass by value to overload the + operator.

  The code won't work if I define the left argument lhs as foo but then it is immutable, and will work if lhs is inout foo, but then I have modified lhs which I clearly do not want.

  A quick breakdown of my class:

  class foo<T: Numeric> {
      /* Data */
      /* Init Fn */
      /* += definition */
      static func + (lhs: foo, rhs: foo) -> foo {
          do {
              try lhs += rhs
              return lhs
          } catch {
              /* Error Handling */
          }
      }
  }
  

  I come from a C++ background, so I am surprised that I am unable to pass the object by value if I choose. Following the question What are the basic rules and idioms for operator overloading?, in C++ this overloading method would expect the left argument to be passed by value and the right argument to be passed by const & as shown below, but here I don't seem to have that option.

  class X {
      /* In Swift operators are not defined internally like this */
      X& operator+=(const X& rhs) {
          // actual addition of rhs to *this
          return *this;
      }
  };
  inline X operator+(X lhs, const X& rhs) {
      lhs += rhs;
      return lhs;
  }
  

  Is there a way that I don't know about, or is overloading done differently in Swift?

  Any help would be greatly appreciated.
• How to add UILabel to UICollectionView Controller

  I created a collectionView Controller in storyboards. Everything works fine , but now i need to create UILabel in CenterX/CenterY position.

• How to keep two versions of an React Native app installed (production and demonstration apps)?

  I am in need of advice of how to deal with something:

  I have an app that will soon be published to App Store and Google Play and I would like to find a way to have a clone of this app with the purpose to give a taste of the app for users and also for the salesman of the company to demonstrate to possible users but also I would like to keep both apps installed, so in the case of the salesman he would be able to demonstrate and also use the real app.

  I know that I could just have a beta user group on TestFlight and Google Play but that would need me to register those users or also give them a link and would not be possible to have both apps installed.

  I would just like to make this "demonstration app" to be downloadable from the stores, it would have different API calls from the Real app, but I would like to avoid having to maintain and copying every change from the "production" app to the "demo" app.

  The option I thought: create a branch and rename the app to the new signature, name, icons and so I will just have to always pull the diff from the origin/master branch and publish it on the stores.

  I would appreciate to receive ideas and workarounds for this.
