In-App Purchase not working, showing No Products

Question

I am learning about In-App Purchase provided by Apple. So I was following this tutorial : http://www.appcoda.com/in-app-purchase-tutorial/

I followed all the steps in this tutorial. Firstly, I created an app id,and then created an app in iTunes using that app id. Then I created two In-App purchase with product id as "com.outlines.feature1" and "com.outlines.feature2", both of them consumable. The rest of the code I simply followed the steps from the above tutorial

import UIKit
import StoreKit

protocol IAPurchaceViewControllerDelegate {
    func didBuyColorsCollection(collectionIndex: Int)
}


class IAPurchaceViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, SKProductsRequestDelegate, SKPaymentTransactionObserver {

@IBOutlet weak var tblProducts: UITableView!

var delegate: IAPurchaceViewControllerDelegate!

var selectedProductIndex: Int!
var transactionInProgress = false

let productIdentifiers = NSSet(array: ["com.outlines.feature1", "com.outlines.feature2"])
 var product: SKProduct?
var productsArray = Array<SKProduct>()

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    tblProducts.delegate = self
    tblProducts.dataSource = self

    //checks whether the In-App feature is activated or not
    requestProductInfo()

    SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}

func requestProductInfo(){
    if SKPaymentQueue.canMakePayments() {
        let request = SKProductsRequest(productIdentifiers:
            productIdentifiers as! Set<String>)
        print("This is the request to be sent \(request)")
        request.delegate = self
        request.start()//calls productsRequest() function
    }
    else {
        print("Cannot perform In App Purchases.")
    }
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

// MARK: IBAction method implementation

@IBAction func dismiss(sender: AnyObject) {
    dismissViewControllerAnimated(true, completion: nil)
}


// MARK: UITableView method implementation

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}


func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return productsArray.count
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("idCellProduct", forIndexPath: indexPath) as UITableViewCell

    let product = productsArray[indexPath.row]
    cell.textLabel?.text = product.localizedTitle
    cell.detailTextLabel?.text = product.localizedDescription

    return cell
}


func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    selectedProductIndex = indexPath.row
    showActions()
    tableView.cellForRowAtIndexPath(indexPath)?.selected = false
}

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return 80.0
}

func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
    if response.products.count != 0 {
        for product in response.products {
            productsArray.append(product as SKProduct)
        }

        tblProducts.reloadData()
    }
    else {
        print("There are no products.")
    }

    if response.invalidProductIdentifiers.count != 0 {
        print("Invalid "+response.invalidProductIdentifiers.description)
    }
}

func showActions() {
    if transactionInProgress {
        return
    }

    let actionSheetController = UIAlertController(title: "IAPDemo", message: "What do you want to do?", preferredStyle: UIAlertControllerStyle.ActionSheet)

    let buyAction = UIAlertAction(title: "Buy", style: UIAlertActionStyle.Default) { (action) -> Void in
        let payment = SKPayment(product: self.productsArray[self.selectedProductIndex] as SKProduct)
        SKPaymentQueue.defaultQueue().addPayment(payment)
        self.transactionInProgress = true
    }

    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) { (action) -> Void in

    }

    actionSheetController.addAction(buyAction)
    actionSheetController.addAction(cancelAction)

    presentViewController(actionSheetController, animated: true, completion: nil)
}

func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    for transaction in transactions as [SKPaymentTransaction] {
        switch transaction.transactionState {
        case SKPaymentTransactionState.Purchased:
            print("Transaction completed successfully.")
            SKPaymentQueue.defaultQueue().finishTransaction(transaction)
            transactionInProgress = false
            delegate.didBuyColorsCollection(selectedProductIndex)

        case SKPaymentTransactionState.Failed:
            print("Transaction Failed");
            SKPaymentQueue.defaultQueue().finishTransaction(transaction)
            transactionInProgress = false

        default:
            print(transaction.transactionState.rawValue)
        }
    }
}  
}

There are no errors, but the when I run it on iPhone, the console shows:

This is the request to be sent <SKProductsRequest: 0x15d86210>
There are no products.
Invalid ["com.outlines.feature1", "com.outlines.feature2"]

The console shows no products, however I have added two in-app features in my iTunes id. Here is the screenshot:

Can anyone tell me what I am doing wrong??

Answer 1

I solved it finally. There were no errors in the code nor in the In-App purchase making process. The earlier solution mentioned to upload a snapshot was also not the issue.

The issue was the contract in the Agreements, Tax and Baking. It was not mentioned in the tutorial, but we need to complete a contract in the Agreements, Tax and Banking in the iTunes, which I had not done. After filling up the forms for the contract, it will be processed. Then the contract will be in effect and then the In-App Purchases created in the iTunes will be recognized.
