iOS - In-App Purchase - Invalid product Identifier

Question

I am trying to integrate In-App Purchases in my project. I have used a third party library, SwiftyStoreKit, as IAP helper.

I'm trying to fetch the information of my In-App products, but always get a response that Invalid Product Identifiers

All my agreements are in Effect (Paid and Free). Also, My In-App Product status shows Waiting for Upload. My App is yet to be release, so I'm testing it in Sandbox Mode.

Following in my code:

import UIKit
import StoreKit
import SwiftyStoreKit

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

override func viewDidAppear(_ _animated: Bool) {
    super.viewDidAppear(_animated)

    if dataModel.lists.count >= 2 {
        getInfo()
    }
}

func getInfo() {

    NetworkActivityIndicatorManager.NetworkOperationStarted()

    SwiftyStoreKit.retrieveProductsInfo([productIdentifier], completion: { result in

        NetworkActivityIndicatorManager.networkOperationFinished()

        self.showAlert(alert: self.alertForProductRetrievalInfo(result: result))

    })
}

I had the same exact problem, but the solutions above did not work for me.

This is what did:

It turns out I hadn't filled out the proper payments and W9 form on AppStoreConnect.

Go to AppStoreConnect > Agreements, Tax, and Banking...

Fill out the "Paid Apps" contract if it hadn't already been filled out

In most cases, this is an error to fix. – oskarko Feb 02 '22 at 10:32
I just found out my agreement was expired. – Zahid Usman Cheema Feb 12 '23 at 09:47

Check your productIdentifier! It should be the same string as registered in iTunes Connect. E.g "com.myapp.myPurchase"

Yes, it is same. Infact, I copied it from iTunes and used it in my code – Vaibhav Jhaveri Apr 10 '17 at 05:28
@VaibhavJhaveri your status for IAP should be Ready to Submit – Evgeniy Gushchin Apr 10 '17 at 05:32
How? There is no button to Submit the IAP – Vaibhav Jhaveri Apr 10 '17 at 05:40

Delete the app from your device. Then install the app back onto the device using Build & Run with your device tethered to your Mac. It should work now – Sivajee Battina Apr 10 '17 at 05:40

Did you complete financial requirements? – Sivajee Battina Apr 10 '17 at 05:44
@SivajeeBattina what financial requirements? I have all the contracts in Effect, both for Free and Paid Application – Vaibhav Jhaveri Apr 10 '17 at 05:46
@VaibhavJhaveri did you upload your app to iTunes Connect? – Evgeniy Gushchin Apr 10 '17 at 05:55

Your in-app product status showing as "waiting for upload" right. May be that is the issue. First reject the old binary. Then delete the in app purchase newer version and then re-upload the binary. Doing this may change your status – Sivajee Battina Apr 10 '17 at 05:57
@SivajeeBattina here is the screen shot of IAP - http://prntscr.com/euk31t – Vaibhav Jhaveri Apr 10 '17 at 06:01
Please wait till that status change or else do the above step if that status lasts for a long time – Sivajee Battina Apr 10 '17 at 06:03
Ohk. It has been days since the IAP shows Waiting for Upload – Vaibhav Jhaveri Apr 10 '17 at 06:05
@SivajeeBattina how long does it take for an IAP to get approved? – Vaibhav Jhaveri Apr 10 '17 at 06:17

It takes almost same time like an app review. It's around 2-3 days – Sivajee Battina Apr 10 '17 at 06:21

You don't need an IAP approval to test in sandbox. Go through this checklist http://stackoverflow.com/questions/11387403/inapppurchase-invalid-product-identifiers-possible-reasons – Aravind Bhuvanendran Apr 10 '17 at 06:59

This is what worked for me:

I was confusing the reference name ( left side ) with the Product ID ( right side )

So make sure that you're using iTunes Connect's Product ID in your code.

I had the exact same error and running this code in the app delegate seemed to fix my problem because by adding your app's observer at launch ensures that it will persist during all launches of your app, thus allowing your app to receive all the payment queue notifications.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
 // see notes below for the meaning of Atomic / Non-Atomic
 SwiftyStoreKit.completeTransactions(atomically: true) { purchases in
     for purchase in purchases {
         switch purchase.transaction.transactionState {
         case .purchased, .restored:
             if purchase.needsFinishTransaction {
                 // Deliver content from server, then:
                 SwiftyStoreKit.finishTransaction(purchase.transaction)
             }
             // Unlock content
         case .failed, .purchasing, .deferred:
             break // do nothing
         }
     }
 }
    return true
}

Make sure you add the "In-App Purchase" to your project from Xcode - Target - Signing & Capabilities.

Remember to make your In-App Ready To Submit status.

If your In-App has different status, then it always return invalid product identifier.
