<p>when I try to open the file xcodeproj, xcode does not start and waits indefinitely until the force exit.</p>

<p>My ionic info : </p>

<pre><code>Your system information:

    Cordova CLI: 6.3.1
    Ionic Framework Version: 1.3.1
    Ionic CLI Version: 2.0.0-beta.37
    Ionic App Lib Version: 2.0.0-beta.20
    ios-deploy version: 1.8.6

</code></pre>

<p>worth mentioning that I am currently using MacOS Sierra GM and Xcode 8 gm.</p>

<p>Edit : when creating a new project and replace the www directory with the version in my project, I can build ios, but once you modify any file no longer compile I can, being hung on the screen above.</p>
