I've built an iOS app that has a handful of provisioned devices assigned within the Apple Developer Center. Do I need to build a new app if I want to add additional provisioned devices to the list, or does that just get controlled and pushed from the Developer site?
You don't need to rebuild the app, but you need to re-sign it using the new mobile provision file.
Specifically, when you add new devices in the Apple Developer Center, you need to do the following:
1. Edit your developer mobileprovision files, and select the newly added UDIDs. Download that mobileprovision file.
2. Use the App Signing Tool to re-sign the app using the new mobile provision file.
3. Make the newly signed app available to the new users.
