What is the best way to wrap `purchaserInfo` for easy comparisons throughout your code using RevenueCat

Question

What would be the best way to wrap Purchases.shared.purchaserInfo to just return true or false when doing multiple comparisons in an If statement.

What I want to be able to do is to quickly check if the user has access to PRO features by having a method or a property that return true or false since I need to make multiple checks in an if statement, something like... if userHasAccess && someOtherCheck { // do something}

Is this a valid solution?

Singleton Class:

    class IAPHelper {

        static let shared = IAPHelper()

        func hasAccessToProFeatures()->Bool{
            var hasAccess:Bool?
            Purchases.shared.purchaserInfo { (purchaserInfo, error) in
                if let purchaserInfo = purchaserInfo {
                    if purchaserInfo.activeEntitlements.contains("myEntitlement") {
                        hasAccess = true
                    }else{
                        hasAccess = false
                    }
                }
            }
            return hasAccess!
        }
    }

Usage:

    if IAPHelper.shared.hasAccessToProFeatures() && someOtherCheck{
        // unlock PRO features
    }

Shared instances are not bad, however for such a small class you could declare hasAccessToProFeatures as a static variable instead.

class IAPHelper {

static var hasAccessToProFeatures: Bool {

    var hasAccess:Bool?
    Purchases.shared.purchaserInfo { (purchaserInfo, error) in
        if let purchaserInfo = purchaserInfo {
            if purchaserInfo.activeEntitlements.contains("myEntitlement") {
                hasAccess = true
            }else{
                hasAccess = false
            }
        }
    }

    guard let isProMember = hasAccess else {
        return false
    }

    return isProMember

  }

}

Then you could call it like:

if IAPHelper.hasAccessToProFeatures && someOtherCheck {
    // unlock PRO features
}

@ Barnyard - I like your approach, but I think the `else` clause in `if purchaserInfo.activeEntitlements.contains("myEntitlement")` is redundant and can be removed since the `guard let` is taking care of that, right? – fs_tigre Jun 26 '19 at 11:37

You are right, guard will take care of instances where the `hasAccess` is false. – Barnyard Jun 26 '19 at 11:51

You could also replace the guard and current return statement with `return hasAccess ?? false`. – Barnyard Jun 26 '19 at 11:56
