I also updated to XCode 8 and ran into this as well. Both the Provisioning Profile and Provisioning Profile (Deprecated) were set as blank on my project in XCode 8.
I tried setting them back to what they were for each environment but the Debug environment had all of the options in the dropdown removed.
After creating an Archive and uploading to iTunes Connect I got a notice that the provisioning profile wasn't quite correct, which was working fine prior to XCode 8.
Following what the others have posted about XCode 8 getting an update to its Signing, I went to the general tab and noticed a new section that allows you to have XCode automatically manage the signing. I checked that box and now it looks like this:
I have not uploaded a new Archive to iTunes Connect yet but when I do I'll add an update here to see if it's resolved the Provisioning Profile warning.
UPDATE:
After selecting Automatically manage signing in XCode and re-sending to the App Store it's still complaining so that didn't quite work. Might have to remove and re-create all provisioning profiles to get this working. What a pain. Thanks Apple.
In Provisioning Profile (Deprecated) description, information is The UUID of a valid provisioning profile. A missing or invalid profile will cause a build error (deprecated, use [PROVISIONING_PROFILE_SPECIFIER] instead).
User interface for managing signing certificates and provisioning profiles has been changed at Xcode 8.3 beta 2.
Changed the user interface for managing signing certificates and
provisioning profiles. Certificates are managed from the Accounts
preferences pane by selecting a team and clicking Manage Certificates.
Automatically managing signing is recommended, however if your app
requires manually signing provisioning profiles are managed in the
General tab of the project editor. Use the Provisioning Profile
dropdown to import or download profiles. In addition it displays
profiles that match the current signing configuration of the target.

Why is one deprecated?
I think Its deprecated because the signing system has been rewritten in Xcode8.
The signing system has been rewritten to include a new mode for
automatically managing signing assets, in addition to a dedicated
manual mode where the profiles for the target must be explicitly
selected. When automatically managing signing assets, Xcode will
create signing certificates, update app IDs, and create provisioning
profiles. For manual mode, only custom created profiles can be
selected and Xcode will not modify or create any signing assets. Xcode
now encodes profiles in the target using the
PROVISIONING_PROFILE_SPECIFIER build setting. This setting allows
specifying both the team ID and the name or identifier of the profile.

There are some Signing relate known Issues with Xcode 8.1 you should known.
So maybe we should not set Provisioning Profile in Build Setting tab, switch to General tab , and set in Signing category instead.
If you set provisioning profile in Build Setting and enable Automatically manage signing in General tab Xcode will complain about that.
Please follow these steps
Hope that helps !
