In iTunes Connect it is possible to give a free trial period for autorenewable subscriptions.
App > Manage In App Purchases > Subscription Basic > 1 Month > Offer a free trial?
How can I get this information on the client? SKProduct
does not have any information about this as I can see. Since we're having a marketing campaign it is very confusing for the end user to not see information about the product has a trial period.
Of course it is possible to fetch this kind of information from a server I maintain, but then we'll have the overhead with updating both our server and iTunes Connect. So I don't accept this kind of answer unless it is wired up to retrieving that trial period information from Apple's services.
