iOS: reliably get originalApplicationVersion without prompting for AppStore login

Hello all,

I’d like to check the originalApplicationVersion for my iOS app, without prompting the user to login to their AppStore account.

Your “converting a paid iOS app to subscription” blogpost has the following code, which looks like it should do what I want:

if let receiptURL = Bundle.main.appStoreReceiptURL,

   let _ = try? Data(contentsOf: receiptURL) {

    Purchases.shared.restoreTransactions { (info, error) in

        completion?(info)

    }

}
 

This implies that it’s safe to call restoreTransactions if we’re certain that there is a receipt on the device.

However, the (recently renamed) restoreTransactions function has a refresh policy of .always, which I suspect might prompt the user to login.

So my questions:

• will restoreTransactions ever prompt for AppStore login if there is a receipt on the device?
• if that function might prompt, is there a reliable way to get originalApplicationVersion from an on-device receipt without prompting?

Thank-you!
