There is SDK and Example provided by PayU for swift at https://codeload.github.com/payu-intrepos/PayUMoney-IOS-SDK/zip/master

If you want to integrate payU then you have to make bridge to use the SDK.

Here is my answer for Swift 2.3, : https://stackoverflow.com/a/41256507/3548469

You will easily able to convert in swift 3.0.

Hi dev My friend said use Stripe framework its better to integrate is this better way to implement – sam May 03 '17 at 07:34
Hi Sam, You can use stripe , stripe is way easy and convenient to use when comparing to integration. If you payu is not compulsory then you should opt for stripe. – Devang Tandel May 03 '17 at 07:52
if pay u is not compulsory then you may go for stripe it totally upto you. – Devang Tandel May 03 '17 at 07:53

Pay u Is compulsory for my app – sam May 03 '17 at 08:31

 import UIKit

var merchantKey = "your live merchant key"
var salt = "your live merchant salt"
var PayUBaseUrl = "https://secure.payu.in"

class PaymentScreen: UIViewController,UIWebViewDelegate {

  @IBOutlet weak var myWebView: UIWebView!

  override func viewDidLoad() {
    super.viewDidLoad()
    self.payPayment()
  }

  func payPayment() {

    var i = arc4random()

    let amount = "1"
    let productInfo = "product"
    let firstName = "SampleName"
    let email = "xxx@gmail.com"
    let phone = "9876543210"
    let sUrl = "https://www.google.com"
    let fUrl = "https://www.bing.com"
    let service_provider = "payu_paisa"

    let strHash:String = self.sha1(String.localizedStringWithFormat("%d%@", i, NSDate()))

    let rangeOfHello = Range(start: strHash.startIndex,
                             end: strHash.startIndex.advancedBy(20))
    let txnid1 = strHash.substringWithRange(rangeOfHello)

    let hashValue = String.localizedStringWithFormat("%@|%@|%@|%@|%@|%@|||||||||||%@",merchantKey,txnid1,amount,productInfo,firstName,email,salt)

    let hash=self.sha1(hashValue)

    let postStr = "txnid="+txnid1+"&key="+merchantKey+"&amount="+amount+"&productinfo="+productInfo+"&firstname="+firstName+"&email="+email+"&phone="+phone+"&surl="+sUrl+"&furl="+fUrl+"&hash="+hash+"&service_provider="+service_provider

    let url = NSURL(string: String.localizedStringWithFormat("%@/_payment", PayUBaseUrl))

    print("check my url", url, postStr)

    let request = NSMutableURLRequest(URL: url!)

    do {

      let postLength = String.localizedStringWithFormat("%lu",postStr.characters.count)
        request.HTTPMethod = "POST"
        request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Current-Type")
        request.setValue(postLength, forHTTPHeaderField: "Content-Length")
        request.HTTPBody = postStr.dataUsingEncoding(NSUTF8StringEncoding)
        myWebView.loadRequest(request)
    } catch {

    }

  }

  func webViewDidStartLoad(webView: UIWebView) {

  }

  func webViewDidFinishLoad(webView: UIWebView) {

    let requestURL = self.myWebView.request?.URL
    let requestString:String = (requestURL?.absoluteString)!

    if requestString.containsString("https://www.google.com") {
        print("success payment done")
    }
    else if requestString.containsString("https://www.bing.com") {    
        print("payment failure")
    }
  }

  func webView(webView: UIWebView, didFailLoadWithError error: NSError?) {
    print("double failure")
  }

  func sha1(toEncrypt:String) -> String {
    let data = toEncrypt.dataUsingEncoding(NSUTF8StringEncoding)!
    var digest = [UInt8](count:Int(CC_SHA512_DIGEST_LENGTH), repeatedValue: 0)
    CC_SHA512(data.bytes, CC_LONG(data.length), &digest)
    let hexBytes = digest.map { String(format: "%02x", $0) }
    return hexBytes.joinWithSeparator("")
  }
}
