Quick Start

1. Initialize the validator:

import StoreKit
import Iaptic

let iaptic = Iaptic(
    appName: "your-app-name",
    publicKey: "your-public-key"
)

2. Validate purchases:

// During purchase
let result = try await product.purchase()
switch result {
case .success(let verificationResult):
    let validationResult = await iaptic.validate(
        productId: product.id, 
        purchaseResult: result
    )
    
    if validationResult.isValid {
        // Grant entitlements
    }
    
// During app launch
for await verificationResult in Transaction.updates {
    if case .verified(let transaction) = verificationResult {
        let validationResult = await iaptic.validate(
            productId: transaction.productID,
            verificationResult: verificationResult
        )
        
        if validationResult.isValid {
            // Update entitlements
        }
    }
}
