Reasons for SKProductsRequest returning 0 products?

Question

I'm trying to set up IAP but after making a call to retrieve the products using SKProductsRequest the SKProductsResponse array within my delegate has a count of 0. Here's my checklist:

Test product has been added to iTunes connect
The product's bundle id matches the app bundle id (and its not using a wildcard)
The product identifier set in the SKProductRequest matches the product created on iTunes connect
I've waited several hours since the product was created on iTunes connect
The provisioning profiles enable IAP
Followed all steps in various tutorial such as http://troybrant.net/blog/2010/01/in-app-purchases-a-full-walkthrough/ etc.
Have deleted app from device, relaunched Xcode, rebuilt etc. etc.

Any other suggestions as to why the fetched product count is zero?

I don't believe this will be a coding issue, but here it is anyway:

…

NSSet *productIdentifiers = [NSSet setWithObjects:@"redacted", nil];
self.productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
self.productsRequest.delegate = self;
[self.productsRequest start];

…
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray *products = response.products;
    NSLog(@"Product count: %d", [products count]);
    for (SKProduct *product in products)
    {
        NSLog(@"Product: %@ %@ %f", product.productIdentifier, product.localizedTitle, product.price.floatValue);
    }
}

Compare your code with the following code, that worked for me: github.com/wolf81/NewsHack/blob/master/FSProductStore.m — Wolfgang Schreurs
Thanks, but I don't believe it can be a code issues as there are only several lines so far. Adding them above anyway — Gruntcakes
I think you could just copy my class, change some identifiers and try to use it for purchase? Perhaps your issue is the environment you test with. — Wolfgang Schreurs
The code I have posted is effectively already identical to the relevant portions of your code. What environmental factors need to be taken into consideration? — Gruntcakes
Whether you connect to the production or test environment is one of the things you might have to keep in mind. — Wolfgang Schreurs

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)
        }

    }
}
