ios ad-hoc profile ignored when archiving

Question

I have created an ad-hoc distribution profile. I am trying to load the app to the app store for beta testing only. However, when I run the xcode (using xcode 7) archive it ignores the build settings and switches to the non-ad-hoc distribution profile.

I have read many threads and I am still not clear if

1. I should care that it is doing that
2. If I should care then why is it happening? The ad-hoc profile is active.

Answer 1

Since you're uploading to the AppStore, you need to use AppStore distribution provisioning profile. You can still use your ad-hoc profile when exporting for ad-hoc deployment. (TestFlight is an integral part of the AppStore now, and is not considered ad-hoc distribution platform anymore...)

From Test Flight Beta Testing:

You should take the following steps to set up prerelease versions of your app for testing in iTunes Connect:

Generate a new App Store Distribution profile containing the beta entitlement to distribute builds via TestFlight.
