I have added some new devices. How can I refresh the provisioning profile, as Xcode 8 automatically manages signing assets?
I have found this question: Refresh devi
To add devices to your provisioning profile in Xcode 8 with automatic code signing, you simply need to build to the device in Xcode. Xcode will add the device's UDID and regenerate the provisioning profile automatically. If you don't have physical access to the device, I don't think there is a way to add it to your provisioning profile without going back to manually managing your devices and profiles.
