title: Profile doesn't match Application Identifier com.domainname.helloworld
body: <p>I try to run a HelloWorld project into my client device, the application identifier in Xcode is: <code>com.domainname.HelloWorld</code>, and when i created the provisioning profile, in the AppID, i have putted: <code>com.domainname.helloworld</code> (lower case).</p>
  
  <p>Now, in Xcode, i try to assign the code signing identity to the provisioning profile i have created, however, in the drop list, i can see the provisioning profile but i can't select it.</p>
