title: Access Windows/Mac Shared Folder Locally With smb from iOS
body: <p>I am trying to build an app where I am able to access(read/write) windows/mac shared folders in my local network with swift. </p>
  
  <p>Is there any possible way to do that with swift?</p>
  
  <p>There is an App in the App Store called "FileExplorer" <a href="https://apps.apple.com/de/app/fe-file-explorer-file-manager/id510282524" rel="nofollow noreferrer">https://apps.apple.com/de/app/fe-file-explorer-file-manager/id510282524</a> where you can access these shared folders, but I do not know how they programmed this and with which language.
  I also tried to access my shared folders via this App and yes it worked I can see my shared folders on my Phone.</p>
  
  <p>But there needs to be a way to do it with swift...</p>
  
  <p>I already tried different things(code bellow). 
  In the code bellow I tried to access the shared folder of my second mac and write the Text "Write this text to the fileURL as text in iOS using Swift" into the file named "Test.txt" and after that I want to read the same file again. </p>
  
  <pre><code>@IBAction func Button(_ sender: UIButton)
  {
      var uc = URLComponents()
      uc.scheme = "smb"
      uc.user = "user"
      uc.password = "password"
      uc.host = "ip-adress"
      uc.path = "document-directory"
  
      // Save data to file
      let fileName = "Test"
      let url = uc.url
      //let DocumentDirURL = URL(fileURLWithPath: "/Users/f/d/t/App/Assets/Apps/TestApp")
      let DocumentDirURL = try! URL(resolvingAliasFileAt: url!)
      let fileURL = DocumentDirURL.appendingPathComponent(fileName).appendingPathExtension("txt")
      print("FilePath: \(fileURL.path)")
  
  
      let writeString = "Write this text to the fileURL as text in iOS using Swift"
      do {
          // Write to the file
          try writeString.write(to: fileURL, atomically: true, encoding: String.Encoding.utf8)
      } catch let error as NSError {
          print("Failed writing to URL: \(fileURL), Error: " + error.localizedDescription)
      }
  
  
  
      var fullString: String = "" // Used to store the file contents
      do {
          // Read the file contents
          fullString = try String(contentsOf: fileURL, encoding: .utf8)
  
      } catch let error as NSError {
          print("Failed reading from URL: \(fileURL), Error: " + error.localizedDescription)
      }
      print("File Text: \(readString)")
  }
  </code></pre>
  
  <p>If I run the code as shown, he always gives me the error
  "smb scheme is not supported" and then some additional errors that he can not write/read the file because he can not access it.</p>
  
  <p>When I change the code and only search on the device I am programming on and run the simulator to search for this file everything works fine. So I have problems with "smb".</p>
  
  <p>Thank you for every helpful answer.  </p>
