IOS app 'The application could not be verified' on IPhone 6

Question

The app which i created worked well in all devices other than IPhone6 . I got the following error message in XCODE 'The application could not be verified.' . I deleted the app and then reinstalled it as per the suggestion given in the link:

iOS app 'The application could not be verified' only on one device

I want to know that what might be the actual cause of this error message. !!

Answer 1

I don't think, this is an xCode issue. This can happen under many conditions. Like-

• Provisioning Profile mismatch:

  Scenario 1:

  When first time, you had built or installed the app in your device, you may have used a different certificate(paired with a different provisioning profile) than now. So, when you try to re-run the app, the device got confused. The ways to fix it-

  1. Delete the existing app and re-build. That way, you don't have to figure out which certificate, you used the first time.

  2. However, if you know which certificate and provisioning profile you used earlier, then just switch to those.

  Scenario 2:

  May be you are trying to use distribution profile where you supposed to use development profile.Fix-

  Assign any valid development provisioning profile under the code signing.

• Device not added:

  1. May be the device is not added in your developer account under Devices or

  2. May be the device is added under Devices, but when you created the provisioning profile, you forgot to select the device on which you are trying to run your app.
