title: "No valid iOS code signing keys found in keychain"
body: <p>I want to test an iOS application using Xamarin Test Recorder using iOS simulator. To do that I want to publish the project. When trying to publish it for archive, I got this error:</p>
  
  <pre><code>/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets: Error: No valid iOS code signing keys found in keychain. You need to request a codesigning certificate from https://developer.apple.com. (MobileApp1.iOS)
  </code></pre>
  
  <p>Do we need a certificate to publish the project?
      When I drag and drop the .app to simulator it doesn't get installed. When I tried to install debug version it gives below error. Failed to chmod /Users/../Library/Developer/CoreSimulator/Devices/8A0508B3-0‌​2E8-4601-A239-B6712F‌​67FF4D/data/Library/‌​Caches/com.apple.con‌​tainermanagerd/Bundl‌​e/Application/1B8A7B‌​17-D9D0-44A6-8584-65‌​7FF1AB5815/MobileApp‌​1.app/MobileApp1 : No such file or directory" Release app also not get installed(No error or warning). Note that this is a xamarin project.What shall I do now?</p>
