Hi I am very new to swift. What I have tried till now is import UIKit import Foundation import Security // Custom URLSessionDelegate class SSLPinningDelegate: NSObject, URLSessionDelegate { let certificate: SecCertificate let privateKey: SecKey init(certificate: SecCertificate, privateKey: SecKey) { self.certificate = certificate self.privateKey = privateKey } func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) { if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodClientCertificate { let credential = URLCredential(identity: privateKey as! SecIdentity, certificates: [certificate], persistence: .forSession) completionHandler(.useCredential, credential) } else { completionHandler(.performDefaultHandling, nil) } } } @objc(AzureProvisionWithCertificate) class AzureProvisionWithCertificate: NSObject { @objc(provisionAndUploadFile:withRegistrationId:withKey:withCertificate:withProvisionHost:withFileNameWithFolder:withModelId:withResolver:withRejecter:) func provisionAndUploadFile(scopeId:String, registrationId:String, key:String, certificate:String, provisionHost:String, fileNameWithFolder:String, modelId:String, resolve:@escaping RCTPromiseResolveBlock, reject:@escaping RCTPromiseRejectBlock) -> Void { print("started: provisionAndUploadFile api") // Create a session with the SSLPinningDelegate let sslPinningDelegate = SSLPinningDelegate(certificate: certificate as! SecCertificate, privateKey: key as! SecKey) print("sslPinningDelegate: \(sslPinningDelegate)") // Create the URL let url = URL(string: "https://global.azure-devices-provisioning.net/\(scopeId)/registrations/\(registrationId)/register?api-version=2021-06-01")! // Create the request var request = URLRequest(url: url) request.httpMethod = "PUT" request.setValue("application/json", forHTTPHeaderField: "Content-Type") request.setValue("utf-8", forHTTPHeaderField: "Content-Encoding") // Create the request body let bodyData = ["registrationId": registrationId] let jsonData = try? JSONSerialization.data(withJSONObject: bodyData) // Set the request body request.httpBody = jsonData // Create the session configuration let sessionConfig = URLSessionConfiguration.default let session = URLSession(configuration: sessionConfig) // Create the data task let task = session.dataTask(with: request) { (data, response, error) in if let error = error { print("Error: \(error.localizedDescription)") reject("Error", error.localizedDescription, error) } else if let data = data { // Process the response data let responseString = String(data: data, encoding: .utf8) print("Response data: \(responseString)") resolve("Response data: \(responseString)") } else { print("No data received") reject("Error", "No data received", nil) } } // Start the data task task.resume() } } Please help me to correct it.

Hi I have updated the code but I am getting error : Cannot find 'SecIdentityCreateWithCertificate' in scope import Foundation import Security import UIKit class URLSessionPinningDelegate: NSObject, URLSessionDelegate { var identity: SecIdentity init(identity: SecIdentity) { self.identity = identity } func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) { let credential = URLCredential(identity: self.identity, certificates: nil, persistence: .forSession) completionHandler(.useCredential, credential) } } func loadIdentity(certPath: String, keyPath: String) -> SecIdentity? { guard let certData = try?
