@cwinUser apologies for the very late reply, this has not been fixed until recently.

Trial Period

Starting from version 0.9.0, you can now verify if a subscription is within the trial period or not.

The result returned when you call verifySubscription will tell you if the subscription is purchased or expired:

// Verify subscription result
public enum VerifySubscriptionResult {
    case purchased(expiryDate: Date, items: [ReceiptItem])
    case expired(expiryDate: Date, items: [ReceiptItem])
    case notPurchased
}

You can read the latest subscription period like this:

switch result {
case .purchased(let expiryDate, let items): 
  if let mostRecent = items.first {
     print("Active, isTrial: \(mostRecent.isTrialPeriod)")
  }
case .expired(let expiryDate, let items):
  if let mostRecent = items.first {
     print("Expired, isTrial: \(mostRecent.isTrialPeriod)")
  }
case .notPurchased:
}

Storing receipt

You don't need to store the receipt yourself, it is already done automatically by StoreKit.

Cancellation

SwiftyStoreKit treats a cancelled product as if the product was never purchased (see https://github.com/bizz84/SwiftyStoreKit/pull/164). This is in accord with Apple guidelines:

Treat a canceled receipt the same as if no purchase had ever been made.

Hope this answers your questions.

I'm going to close this for now, however feel free to reopen if you need more clarifications.

Hi, How does it handle multiple subscription options? What does "VerifySubscriptionResult" represent exactly?
