Update a View after an in app purchase was done - swiftui

Question

In the meantime a try to implement in app purchases in my app that is in the AppStore.
So I done this with Glassfy and everything works fine.
final class IAPManager {
static let shared = IAPManager()
private init() {}
enum Product: String {
case comfirstmember
var sku: String {
"numberOne"
}
}
#AppStorage("boughtFirst") var boughtFirst = false
func configure() {
Glassfy.initialize(apiKey: "31876r5654fgz4f95f0e6e6bh5d")
}
func getProduct(completion: #escaping (Glassfy.Sku) -> Void) {
Glassfy.sku(id: "numberOne") { sku, error in
guard let sku = sku, error == nil else {
return
}
completion(sku)
}
}
func purchase(sku: Glassfy.Sku) {
Glassfy.purchase(sku: sku) { transaction, error in
guard let t = transaction, error == nil else {
return
}
if t.permissions["numberOne"]?.isValid == true {
NotificationCenter.default.post(
name: Notification.Name("numberOne"),
object: nil
)
self.boughtFirst = true
}
}
}
func getPermissions() {
Glassfy.permissions { permissions, error in
guard let permissions = permissions, error == nil else {
return
}
if permissions["numberOne"]?.isValid == true {
NotificationCenter.default.post(
name: Notification.Name("numberOne"),
object: nil
)
self.boughtFirst = true
}
}
}
func restorePurchases() {
Glassfy.restorePurchases { permissions, error in
guard let permissions = permissions, error == nil else {
return
}
if permissions["numberOne"]?.isValid == true {
NotificationCenter.default.post(
name: Notification.Name("numberOne"),
object: nil
)
self.boughtFirst = true
}
}
}
}
But now I need to update a View after the purchase was successfully done buy the user to display the Content that he purchased.
NavigationView {
VStack {
if boughtFirst == false {
BuyExtraContent()
}
if boughtFirst == true {
AllView()
}
}
}
I want do this as easy as possible just with AppStorage.
But if I place the Boolean in the func purchase to switch from false to true nothings changes.
So my question is how I can update a view after a successful purchase.
P.S. I´m a bit lost in SwiftUI so please explain it not to complex :)

Answer 1

use a state variable for this .
you used boughtFirst as a bool variable. make sure it's an observable .
try to call with observable object and when your variable will change the view will automatically notify and update by itself.
I am not sure you followed this strategy or not.
