I fixed mine! If you are getting Error Domain=SKErrorDomain Code=2 "Cannot connect to iTunes Store" error, make sure you insert SKPaymentQueue.default().finishTransaction(transaction). It worked for me after I added SKPaymentQueue.default().finishTransaction(trans) in the following:

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    for trans in transactions{
        if trans.transactionState == .purchased {
            print("Successful.")
            SKPaymentQueue.default().finishTransaction(trans)
        } else if trans.transactionState == .failed {
            print("failed!")
            print(trans.error)
            SKPaymentQueue.default().finishTransaction(trans)
        }
    }
