Error installing application on iPhone 6 device in Xcode 6

Question

I have all the pre-profiles ready for the devices, and they are added to the developer's portal. However, when I tried to run the application from xcode 6 into my new iphone 6 with iOS 8, it causes this error.

any ideas how to fix this? All of my provisioning profiles are valid and active. code signature identification is correct.

when I tried to start another ipad with iOS 8, it causes this error:

Answer 1

it seems that setting a preliminary profile, as automatic will do the trick instead of the app store or Ad hoc profile

Answer 2

You will need to download the provisioning profile from the dev center and install it using keychain. After that, it should work.

Answer 3

I think that something is wrong with your developer certification, try changing the position to solve it.
