Fixing the Razorpay-Pod Issue in Kotlin Multiplatform Mobile (KMM) for iOS

Fixing Razorpay CocoaPod Integration in KMM for iOS

Fixing Razorpay CocoaPod Integration in KMM for iOS

Kotlin Multiplatform Mobile (KMM) enables developers to share code between Android and iOS. However, integrating certain CocoaPods, such as **razorpay-pod**, can be challenging due to naming conventions. This guide provides a step-by-step solution to resolve these issues, ensuring a smooth integration of Razorpay's SDK into your KMM iOS application.

Understanding the Issue

When integrating **razorpay-pod** into a KMM project, developers may encounter errors related to unresolved modules. This often stems from the hyphen in the pod's name, which can cause KMM to misinterpret the module structure, leading to import issues.

Solution: Explicitly Defining the moduleName

Step 1: Update Your Gradle Configuration

In your shared module's build.gradle.kts file, add the following code to explicitly define the module name:

kotlin {
    ios {
        binaries.framework {
            baseName = "shared"
        }
    }
    cocoapods {
        summary = "KMM shared module for iOS"
        homepage = "https://www.kmmprogrammingnest.com"
        ios.deploymentTarget = "14.0"
        podfile = project.file("../iosApp/Podfile")
        
        pod("razorpay-pod") {
            version = "1.4.0"
            moduleName = "Razorpay"
            extraOpts += listOf(
                "-framework", "Security",
                "-framework", "SystemConfiguration",
                "-framework", "WebKit"
            )
        }
    }
}

Step 2: Synchronize and Refresh Your Project

  • **Sync the Gradle files:** In Android Studio, navigate to *File > Sync Project with Gradle Files*.
  • **Invalidate Caches (if necessary):** If issues persist, go to *File > Invalidate Caches & Restart*.

Step 3: Configure Your iOS Podfile

platform :ios, '14.0'

target 'iosApp' do
    use_frameworks!
    pod 'razorpay-pod', '1.4.0'
end

Step 4: Build and Test in Xcode

Import the Razorpay module in your Swift code:

import Razorpay

Test the integration by using the following code in your Swift class:

import UIKit
import Razorpay

class ViewController: UIViewController, RazorpayPaymentCompletionProtocol {
    var razorpay: RazorpayCheckout!
    override func viewDidLoad() {
        super.viewDidLoad()
        self.razorpay = RazorpayCheckout.initWithKey("YOUR_API_KEY", andDelegate: self)
    }
    func onPaymentSuccess(_ payment_id: String) {
        print("Payment Successful: \(payment_id)")
    }
    func onPaymentError(_ code: Int32, description str: String) {
        print("Payment Failed: \(str)")
    }
}

Why This Solution Works

The core issue is that KMM does not automatically resolve CocoaPods with hyphenated names. By explicitly specifying the **moduleName** as **`Razorpay`**, KMM correctly maps the dependency, allowing imports to work without issues.

Following these steps will ensure seamless integration of the Razorpay SDK into your KMM project, avoiding common pitfalls and improving development efficiency.

How to Integrate Razorpay in Kotlin Multiplatform Mobile (KMM) for WebApp JS Browser Target

Integrate Razorpay in KMM for WebApp JS Browser Target How to Integrate Razorpay in Kotlin Multiplatform Mobile (KMM) for WebApp JS Browser Target If you're working with Kotlin Multiplatform Mobile (KMM) and want to integrate Razorpay for payments, you might find plenty of documentation for Android and iOS. However, integrating Razorpay into the WebApp JS Browser target isn't as straightforward. In this blog post, I'll guide you through the steps to get Razorpay working in your KMM project for the WebApp JS Browser target. Why Kotlin Multiplatform Mobile (KMM)? KMM allows you to share business logic across Android, iOS, Web, and other platforms, making it easier to maintain a single codebase. But, when it comes to platform-specific features like payments, you need to implement certain functionality separately for each platform.

Understanding Kotlin Yarn Lock in KMM Projects

Kotlin Yarn Lock in KMM Projects Understanding Kotlin Yarn Lock in KMM Projects As a Kotlin Multiplatform Mobile (KMM) developer, working with JavaScript (JS) targets is a crucial aspect when building truly cross-platform applications. In this post, we’ll dive into the importance of the yarn.lock file in KMM projects, how it functions, and where it fits within your project structure. What is yarn.lock ? The yarn.lock file is a critical component in any KMM project that targets JavaScript, whether it's jsBrowser or jsNode . When managing JavaScript dependencies with Yarn, the yarn.lock file locks down the versions of all installed packages, ensuring that every developer and every environment running your project uses the exact same versions. This consistency is vital for avoiding the dreaded "it works on my machine" problem. Why is yarn.lock Important in KMM? When building a KMM project, you might need to int...
