  <p>I have all of the provisional profiles ready on the devices and it's added to the developer portal.However when I tried to run the app from xcode 6 into my new iphone 6 with iOS 8 on it, it throws me this error.</p>
  
  <p>any ideas how to fix it? all of my provisioning profiles are valid and active. the code signing identity is correct.</p>
