Adding Multiple Arrays to Form One Final Array. Debug Swift Xcode

Adding multiple arrays to form one final array. Debug swift xcode

I think you may have problem problem if you using List model regarding to playing sound of clicked Card one could be better is to modify the Card model with following way

import Foundation; import UIKit; import AVFoundation

var player: AVAudioPlayer?

class Card: NSObject
{
var image: UIImage
var soundUrl: String
var isActive: Bool

init(image: UIImage, soundUrl: String, isActive:Bool = true) {
    self.image = image
    self.soundUrl = soundUrl
    self.isActive = isActive 
}
func playSound()
{
    guard let url = Bundle.main.url(forResource: self.soundUrl, withExtension: "m4a") else { return }
    do
    {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)

        player = try AVAudioPlayer(contentsOf: url)
        guard let player = player else { return }
        player.prepareToPlay()
        player.play()
    print("play")
    } catch let error {
        print(error.localizedDescription)
    }
}
}

Usage
Replace your viewController code with this

 import UIKit

class SecondViewController: UIViewController , UIGestureRecognizerDelegate  {

var imageIndex: Int = 0
  var itemList:[Card] = []

    func addlist(list:[String], flag:Bool)
    {
       for word in list
        {
         itemList.append(Card(image: UIImage(named: word)!, soundUrl: word,isActive:flag))
       }
    }
    override func viewDidLoad() {
      super.viewDidLoad()
    let list1 = ["lake", "lamb", "lamp", "lark", "leaf", "leash", "left", "leg", "lime", "lion", "lips", "list", "lock", "log", "look", "love", "lunch"]
    let list2 = ["ladder", "ladybug", "laughing", "lawnmower", "lemon", "leopard", "leprechaun", "letters", "licking", "lifesaver", "lifting", "lightbulb", "lightning",
                 "listen", "llama"]

                "violin", "xylophone", "yellow"]
    let list4 = ["apple", "ball", "bell", "bubble", "castle", "fall", "fishbowl", "girl", "owl", "pail", "peel", "pool", "smile", "whale", "wheel"]
    let list5 = ["planet", "plank", "plant", "plate", "play", "plum", "plumber", "plus"]

    addlist(list:list9,flag:true);
    addlist(list:list10,flag:true);
    addlist(list:list11,flag:true);

        let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped(tapGestureRecognizer:)))
        imgPhoto.isUserInteractionEnabled = true
        imgPhoto.addGestureRecognizer(tapGestureRecognizer)

        imgPhoto.image = itemList[0].image

        // Do any additional setup after loading the view.

Creating multiple arrays which will add up to one final array. Debugging issue. Swift and Xcode

You're very close; there are a few fixes needed:

Move the imageList computed variable to the class level, instead of inside viewDidLoad.
The imageIndex variable can be an Int instead of an NSInteger. This is not a breaking change, but will make things easier and is better Swift style.
Where you previously used the maxImages variable, you can replace them with imageList.count, which is the total number of elements in the array.

Here is the final, edited code. It compiles; let me know if it works!

class SecondViewController: UIViewController , UIGestureRecognizerDelegate  {

    @IBAction func home(_ sender: Any) {
        performSegue(withIdentifier: "home", sender: self)
    }

    @IBOutlet weak var imgPhoto: UIImageView!

    struct List {
        let words: [String]
        var active: Bool
    }

    let list1 = List(words:["lake", "lamb", "lamp", "lark", "leaf", "leash", "left", "leg", "lime", "lion", "lips", "list", "lock", "log", "look", "love", "lunch"], active: true)

    let list2 = List(words: ["ladder", "ladybug", "laughing", "lawnmower", "lemon", "leopard", "leprechaun", "letters", "licking", "lifesaver", "lifting", "lightbulb", "lightning", "listen", "llama"], active: true)

    let list3 = List(words: ["alligator", "balance", "ballerina", "balloon", "bowling", "cello", "colors", "curlyhair", "dollar", "dolphin", "elephant", "eyelashes", "gasoline", "goalie", "hula", "jellyfish", "olive", "pillow", "pilot", "polarbear", "rollerskate", "ruler", "silly", "telephone", "television", "tulip", "umbrella", "valentine", "violin", "xylophone", "yellow"], active: true)

    let list4 = List(words: ["apple", "ball", "bell", "bubble", "castle", "fall", "fishbowl", "girl", "owl", "pail", "peel", "pool", "smile", "whale", "wheel"], active: true)

    let list5 = List(words: ["planet", "plank", "plant", "plate", "play", "plum", "plumber", "plus"], active: true)

    let list6 = List(words: ["black", "blanket", "blender", "blocks", "blond", "blood", "blow", "blue"], active: true)

    let list7 = List(words: ["flag", "flipflop", "float", "floor", "flower", "fluffy", "flute", "fly"], active: true)

    let list8 = List(words: ["glacier", "glad", "glasses", "glide", "glitter", "globe", "glove", "glue"], active: true)

    let list9 = List(words: ["clam", "clamp", "clap", "claw", "clean", "climb", "clip", "cloud"], active: true)

    let list10 = List(words:["sled", "sleep", "sleeves", "slice", "slide", "slime", "slip", "slow"], active: true)

    let list11 = List(words: ["belt", "cold", "dolphin", "elf", "golf", "melt", "milk", "shelf"], active: true)

    var imageIndex: Int = 0

    var imageList: [String] {

        let wordLists = [list1, list2, list3, list4, list5, list6, list7, list8, list9, list10, list11]

        let active = wordLists.reduce([]) { (result:[String], list:List) in
            if list.active {
                return result + list.words

            } else {
                return result
            }
        }

        return active

    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        imgPhoto.isUserInteractionEnabled = true

        let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(Swiped(gesture:)))
        leftSwipe.cancelsTouchesInView = false

        let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(Swiped(gesture:)))
        rightSwipe.cancelsTouchesInView = false

        leftSwipe.direction = .left
        rightSwipe.direction = .right

        view.addGestureRecognizer(leftSwipe)
        view.addGestureRecognizer(rightSwipe)

    }

    func Swiped(gesture: UIGestureRecognizer) {

        if let swipeGesture = gesture as? UISwipeGestureRecognizer {

            switch swipeGesture.direction {

            case UISwipeGestureRecognizerDirection.right :
                print("User swiped right")

                // decrease index first

                imageIndex -= 1

                // check if index is in range

                if imageIndex < 0 {

                    imageIndex = imageList.count - 1

                }

                imgPhoto.image = UIImage(named: imageList[imageIndex])

            case UISwipeGestureRecognizerDirection.left:
                print("User swiped Left")

                // increase index first

                imageIndex += 1

                // check if index is in range

                if imageIndex > imageList.count - 1 {

                    imageIndex = 0

                }

                imgPhoto.image = UIImage(named: imageList[imageIndex])

            default:
                break //stops the code/codes nothing.
            }
        }
    }
}

Global array not appending

Singletons in swift should have a private initializer so no one can create an instance other than the single shared instance. The single instance is usually called shared. If you want the value to print every time you append an item then you should use a didSet:

struct Interventions {
    static var shared: [String] = [] {
        didSet {
            shared.forEach{print($0)}
        }
    }
    private init() { }
}

How to show all the elements of an array in swift?

You can simply iterate through the array like this and print out all elements on a new line:

for element in array {
  println(element)
}

UPDATE

For Swift 2 and Swift 3:

for element in array {
  print(element)
}

Or if you want it on the same line:

for element in array {
  print(element, terminator: " ")
}

Detect array with issue (Debug mode)

To handle All exceptions, From Xcode click on Show the Breakpoint Navigator

Click + button at bottom side and from pop up click on Add Exception Breakpoint.

Sample Image

This will add exception break points for application, try to run again and execution will stop if any runtime exception raised.

Breaking up one array into multiple arrays in Postman

What is being returned is a list of objects. There is no need of converting that into arrays. you can map inside that one array and access the object.
