Have Multiple Subscription for each products Buttons with different style in SwiftUI

I would like to have different buttons depending on the type of subscription (monthly, yearly) to be able to customize them individually. For the moment my setup works with a For Each (as below) and therefore does not allow me to distinguish between the different products by varying the design of the buttons. 

ForEach(currentOffering!.availablePackages) { pkg in
                    Button {
                        // BUY
                        Purchases.shared.purchase(package: pkg) { (transaction, customerInfo, error, userCancelled) in
                            if customerInfo?.entitlements.alll"pro"]?.isActive == true {
                                // Unlock that great "pro" content

                                userViewModel.isSubscriptionActive = true
                            }
                        }
                    } label: {
                        Text("\(pkg.storeProduct.subscriptionPeriod!.periodTitle) \(pkg.storeProduct.localizedPriceString)")
                    }
                    .buttonStyle(GenerateButtonStyle2())
                }

 

It works perfectly! Thanks so much :)

Hey, @Louis-Auguste 👋 

This is a great question! I’ve attached some sample code below that shows how to do this.

  1. Looks for the `package.storeProduct.subsciptionPeriod?.unit`
    1. This possible values here are `day`, `week`, `month`, and `year`
    2. The below example only looks for month and year as you mentioned in your original question
  2. Switches button styles (or any view content) based on that
var body: some View {
    VStack(spacing: 10) {
        Text("With RevenueCat")
            .padding()

        if let offering = self.offering {
            ForEach(offering.availablePackages) { package in
                Button {
                    Task {
                        try await Purchases.shared.purchase(package: package)
                    }
                } label: {
                    Text(package.storeProduct.localizedTitle)
                }.buttonStyle(self.packageButtonStyle(package))
            }
        }
    }
    .padding()
}

func packageButtonStyle(_ package: Package) -> PackageButtonStyle {
    switch package.storeProduct.subscriptionPeriod?.unit {
    case .month?:
        return PackageButtonStyle(bgColor: .red)
    case .year?:
        return PackageButtonStyle(bgColor: .green)
    default:
        return PackageButtonStyle(bgColor: .gray)
    }
}

struct PackageButtonStyle: ButtonStyle {
    let bgColor: Color

    func makeBody(configuration: Self.Configuration) -> some View {
        configuration.label
            .padding()
            .background(self.bgColor)
            .foregroundColor(.yellow)
            .clipShape(Capsule())
    }
}

Hopefully that helps! Let me know if you have any questions on my sample or any further questions and I’ll be happy to help 😊 

Thanks!
