Self-signed Certificates

In order for the app to interact with locally running service the following changes need to be done:

1. Before running the app in the simulator add these lines of code to the top of the file WalletKitController just below the import statements.

   class SelfSignedDelegate: NSObject, URLSessionDelegate {
     func urlSession(
       _ session: URLSession,
       didReceive challenge: URLAuthenticationChallenge,
       completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void
     ) {
       // Check if the challenge is for a self-signed certificate
       if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust,
          let trust = challenge.protectionSpace.serverTrust {
         // Create a URLCredential with the self-signed certificate
         let credential = URLCredential(trust: trust)
         // Call the completion handler with the credential to accept the self-signed certificate
         completionHandler(.useCredential, credential)
       } else {
         // For other authentication methods, call the completion handler with a nil credential to reject the request
         completionHandler(.cancelAuthenticationChallenge, nil)
       }
     }
   }
   
   let walletSession: URLSession = {
     let delegate = SelfSignedDelegate()
     let configuration = URLSessionConfiguration.default
     return URLSession(
       configuration: configuration,
       delegate: delegate,
       delegateQueue: nil
     )
   }()
   

2. Once the above is in place, add the following line in the initializer in order for the app to interact with web services that rely on self-signed certificates:

   wallet.urlSession = walletSession
