I see it too. It is related to this change: "Xcode 8 does not automatically copy the aps-environment entitlement from provisioning profiles at build time. This behavior is intentional. To use this entitlement, either enable Push Notifications in the project editor’s Capabilities pane, or manually add the entitlement to your entitlements file. (28076333)"
I will further investigate this issue. If you need an immediate solution then you should downgrade to Xcode 7. Note that the hosted builders still run Xcode 7.
