title: Will Xcode 7.3.1 work on macOS 10.12?
body: <p>I want to install and try out the new features of macOS 10.12. Also I really want to work on Xcode 8.0. But the same time I have some client projects which should written on Swift 2.2 [ Xcode 7.3.1 ], I don't want use Swift 2.3 or Swift 3.0.</p>
  <p>So is it possible to install Xcode 7.3.1 in macOS 10.12? Is there any hacky way to do this?</p>
  <hr />
  <p><strong>Yes I have successfully installed both <code>Xcode 7.3.1</code> and <code>Xcode 8.0</code> in my <code>macOS Sierra</code>.</strong></p>
  <p>Now using both Xcodes. But whenever I run my project using <code>Xcode 7.3.1</code> I am getting this error <code>DTAssetProviderService could not start DTXConnection with Simulator 'iPhone 6s'. Check the system log for errors.</code> I don't know the actual reason for this. I have googled for the answers but those suggestions didn't help me. But at the same time I can run projects in Xcode 8.0 in Simulator, no errors, nothing.</p>
  <p>If anyone came to see this, Please let me know your comment.</p>
