Reasons for SKProductsRequest returning 0 products?

Solution 1:

Check all 3 things in the list below
1) check your product identifiers - they must be exactly the same that you have in your code and in iTunes Connect -> My Apps -> YourAppName -> Features -> In-App Purchases 2) iTunes Connect -> Agreements, Tax, and Banking -> Master Agreements -> Paid Applications-> Contact Info / Bank Info / Tax Info (should be filled) 3) code to test it

class ViewController: UIViewController {

    var requestProd = SKProductsRequest()
    var products = [SKProduct]()

    override func viewDidLoad() {
        super.viewDidLoad()

        validateProductIdentifiers()
    }
}

extension ViewController: SKProductsRequestDelegate {

    func validateProductIdentifiers() {
        let productsRequest = SKProductsRequest(productIdentifiers: Set(["candy100", "someOtherProductId"]))

        // Keep a strong reference to the request.
        self.requestProd = productsRequest;
        productsRequest.delegate = self
        productsRequest.start()
    }

    // SKProductsRequestDelegate protocol method
    public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {

        self.products = response.products

        for invalidIdentifier in response.invalidProductIdentifiers {
            print(invalidIdentifier)
        }

    }
}

Solution 2:

Make sure you have In-App Purchase turned on in the Capabilities section. If you don't, SKProductsRequest will return 0 products.

Solution 3:

I was facing the same problem, Solved it by sending just the IAP Product name rather than my bundle id before the product name. Here is the example :

works SKProductsRequest *productRequest = [[SKProductsRequest alloc]initWithProductIdentifiers:[NSSet setWithObject:@"my_product"]];

rather than

doesn't work SKProductsRequest *productRequest = [[SKProductsRequest alloc]initWithProductIdentifiers:[NSSet setWithObject:@"com.my_site.my_app.my_product"]];

Solution 4:

I had the same issue...

I simply change my bundle identifier which does not match with an iTunes bundle identifier.

And my app runs well :)

Solution 5:

In the off chance that you've overlooked this, the product identifier match is case sensitive.

So, if you've created a product on Apple with an identifier of say

com.yourcompany.product1

and you call the product request with a product identifier of

com.yourcompany.Product1

Your list will be returned with zero products.

This kept me busy for a while :-)

ps: On a separate project, I found SKProductsRequest only started returning products after a restart. So, if all else fails, try restarting your Mac.
