I am developing an iOS application which offers in app purchases in the form of subscriptions. I want to extract the renew date and the free trial end date of a given active subscription, if possible.

During the development I found that the Transaction object in StoreKit2 has expirationDate in addition the Transaction has a subscriptionStatus that in turn has renewalInfo. From it I can extract renewalDate.

My question is which of the two should I use and what is the difference?
