Here is the complete process to integrate PayU in iOS using Swift:
1. SignUp with Payu money here.
2. You can find your PayU Test Key & Salt in Business Dashboard. Check the below screenshots reference.
3. You have to download Payu SDK by using the command “$ git clone –recursive https://github.com/payu-intrepos/PayUMoney-IOS-SDK.git” in the terminal. We need Payu Frameworks from this SDK. However, it may fail sometime but it will work. For instance, for me, it failed 8-9 times.
The general error that you can face :

OR
Also, You can download the required frameworks from this link.
4. Open your Xcode project. Move PayUMoney-IOS-SDK/Dependencies/CitrusGraphics/Framework/graphics-sdk/CitrusGraphics.framework into your project. Then, remember to select Add to Targets when moving into the Xcode project.
Next, move PayUMoney-IOS-SDK/CoreSDK/PayUMoneyCoreSDK.framework into your project. After that, add to Targets when moving into the Xcode project.
Then, move PayUMoney-IOS-SDK/PlugNPlay/PlugNPlay.framework into your project. Next, add to Targets when moving into the Xcode project.
5. Note:
If you missed to add targets or you are getting an error that these files are missing or in case you get an Apple o linker error for these files then adds “Target Memberships” to these frameworks.
6. Add the below line in the podfile –
# For payu integration
pod ‘PayUmoney_PnP’# For hash creation
pod ‘CryptoSwift’
7. Run command – pod install
8. After pod installation is complete make sure that you are using “project.xcworkspace” Xcode project.
Note: Please don’t use “project.xcodeproj” Xcode project.
9. To use Objective C code in Swift we need to create a Bridging header. First, you can create a new Bridging header manually and add it to Build settings > Objective -C Bridging Header.
OR
Also, you can create a new C file ( .m file or .h file). It will automatically create a new bridging header.
10. Generally Bridging Header file will be empty. You can add the below code in Bridging Header either at the bottom or at the top of the file –
#import <PlugNPlay/PlugNPlay.h>
11. Import the CryptoSwift library into your controller.
import CryptoSwift
Note: There are chances that you don’t get “CryptoSwift” in the import suggestion. Don’t worry, you can manually type the same code shown above.
12. The function below in your ViewController class where from which you will initiate the PayU transaction.
func setupPayu()
{
var kMerchantSalt = “your salt”
var txnParam = PUMTxnParam()
PlugNPlay.setDisableCompletionScreen(true)
//Set the parameters
txnParam.phone = “8802444107”
txnParam.email = “asharma@velsof.com”
txnParam.amount = “500”
txnParam.environment = PUMEnvironment.test
txnParam.firstname = “Akash”
txnParam.key = “Your Key”
txnParam.merchantid = “Your Merchant id”
txnParam.txnID = “1234567890”
txnParam.surl = “https://www.payumoney.com/mobileapp/payumoney/success.php”
txnParam.furl = “https://www.payumoney.com/mobileapp/payumoney/failure.php”
txnParam.productInfo = “iPhone7”
txnParam.udf1 = “ud1”
txnParam.udf2 = “ud2”
txnParam.udf3 = “ud3”
txnParam.udf4 = “ud4”
txnParam.udf5 = “ud5”
txnParam.udf6 = “”
txnParam.udf7 = “”
txnParam.udf8 = “”
txnParam.udf9 = “”
txnParam.udf10 = “”
/*
* Below code is used to create a formatted hashString from the Payu Transaction parameters
* **Author:** Asharma
* **Date:** 09-Oct-2018
*/
let hashString = “\(txnParam.key!)|\(txnParam.txnID!)|\(txnParam.amount!)|\(txnParam.productInfo!)|\(txnParam.firstname!)|\(txnParam.email!)|\(txnParam.udf1!)|\(txnParam.udf2!)|\(txnParam.udf3!)|\(txnParam.udf4!)|\(txnParam.udf5!)||||||\(kMerchantSalt)”
/*
* Below code is used to create dynamic hash from hashString
* **Author:** Asharma
* **Date:** 09-Oct-2018
*/
let data = hashString.data(using: .utf8)
txnParam.hashValue = data?.sha512().toHexString()
PlugNPlay.presentPaymentViewController(withTxnParams: txnParam, on: self) { (response, error, extraParam) inprint(“response”)
print(error)
}
}
13. When you want to start a PayU transaction, you can call the setupPayu() function. Then, either on the tap of a button or inside another function.
Example: I have created a button on my project. Created an IBAction of the button. This IBAction is a function that will be called on the tap or button that I created.
@IBAction func onTapBtnPay(_ sender: Any) {
setupPayu()
}
14. You have completed the integration part of PayU integration.
