iOS: Swift: MobilePaymentsSDK: Payments screen would not get presented for card reader swipe

[iamchandra]

Thank you for your reply @Bryan-Square

The suggested usage of the methods from SDK might have changed because I get the below errors. Could you please check?

---

Compilation Error - 1

@Bryan-Square

// Verify SDK initialization
    guard MobilePaymentsSDK.shared.isInitialized else {
        print("Square SDK not initialized")
        return
    }

---

Compilation Error - 2

@Bryan-Square

    do {
        try MobilePaymentsSDK.shared.initialize(applicationLaunchOptions: nil)
        print("Square SDK initialized successfully")
    } catch {
        print("Failed to initialize Square SDK: \(error)")
    }

Compilation Error - 3

This error occurs when I add the block to the startPayment method that has check for the result.

// Start payment with completion handler
    DispatchQueue.main.async {
        MobilePaymentsSDK.shared.paymentManager.startPayment(
            paymentParams,
            promptParameters: paymentPromptParameters,
            from: viewController,
            delegate: vc
        ) { result in
            switch result {
            case .success:
                print("Payment screen presented successfully")
            case .failure(let error):
                print("Failed to present payment screen: \(error)")
            }
        }
    }

I am able to add “Near Field Communication Tag Reading” capability. But not “Payment Processing” as such capability is not listed when I searched.

@Bryan-Square

2. Add Required Capabilities In Xcode:

• Enable “Near Field Communication Tag Reading” capability
• Enable “Payment Processing” capability

Thank you much
