Intialize InAppMachine

Step1: InAppMachine follows singleton, so first you shoud access its singleton object rather than creating one,

import UIKit
import InAppMachine

class ViewController: UIViewController {

    // Add This One
    let inappMachine = InAppMachine.shared

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

    }
    
}

Step2:

Now, You have to tell InAppMachine about the Product ID(s) which you have made on iTunes connect. Say, you have created a consumable product named 'co.in.greensyntax.restman.developer.program'

So, you have to adopt 'InAppPurchaseSource' protocol and satisfy the stubs (i.e. products).

import UIKit
import InAppMachine

class ViewController: UIViewController, InAppPurchaseSource {

// Change as per your ProductID
var products: [String] = ["co.in.greensyntax.restman.developer.program"]

let inappMachine = InAppMachine.shared

    override func viewDidLoad() {
        super.viewDidLoad()
    
        // Next, I have set the dataSource with the instance of my object.
        inappMachine.dataSource = self
    }

}

Request Products

Step3: Now, we'll check wheather our ProductID are valid or not. So, we'll call the request method for checking the validity of product.

inappMachine.requestFor(inAppProducts: { (products) in
    
    //onSuccess
    for product in products {
    
        // Valid Product Deatils
        print(product.description)
    }
}) { (error) in
    
    //onError you'll get an error of type InAppError
    print(error?.localizedText)
}

With these details, you can prepare your Purchase View where you can show Products Details.

Purchase

Step4:

And, On Purchase affirmation, you can initiate purchase event with valid Product object. For purchasing, you need an instance of 'InAppProduct' which you got on InApp request call (step3).

self.inappMachine.purcahseFor(product: product, onSuccess: { (transaction: InAppTransaction) in

    //onSuccessfull Transaction
    print(transaction.description)

}, onFailed: { (error) in

    //onFailed Transaction
    print(error)
})

Restore

Recipts

Recipts Validation is usally done to validate the purchase, wheather it's a genuine purchase or not. Say, You have purcahse a InApp product and notifed the your App Server via API that you have purchase this subscription. Now, it's alway a good idea to validate every purchase using reciopts.

// Get Recipts Data to Validate the Purchase
let recipts = inappMachine.getReciptData()
