  I created a TEST Unity3d Project using this tutorial:

  <p>Now i try to build the app in Xcode 8.2.1, but i just get an error:
  ["Unity-iPhone" isn't code signed but requires entitlements. It is not possible to add entitlements to a binary without signing it.

  <p>I found many informations about this in the internet. But nothing worked for me.
  The most informations in internet are for older xcode versions and i think apple changed many about code signing in xcode 8..</p>
  
  <p>In Xcode Preferences, i use a default free AppleID with a default team.

  <p>Trying to disable code signing did not work:

  <p>Completely disable code signing also does not work:

  <p>I use Mac OS El Capitan.
  iPhone 7 v10.2.1</p>
  
  <p>Can anyone help me out?</p>
