Could not launch app (Verify the Developer App certificate)
<p>I have an issue sometime when I run the app in my iPhone with Xcode.

<p>I tried to verify apps in Settings but it didn't work. "Unable to Verify "iPhone Developer: ..." Apps.</p>

<p>I am a Free developer but it normally runs and sometime during 1 hour I can't run anything on my iPhone.</p>

<p>I tried to delete the app and run, to download all profiles in Xcode Settings, same problem.</p>

<p>Do you have any idea to solve it ?</p>

<p>Thanks for your help.</p>
