Beta distributions with Enterprise certificates in iOS 9 and iOS 10
With the release of iOS 9, testers will be required to "trust" your organization’s Apple Enterprise developer certificate, one-time, before running Beta distributions.
Testers will see the message “Untrusted Enterprise Developer” when running an app from an untrusted certificate and can trust it by following the steps outlined below on their device.
- Navigate to Setting > General > Profiles & Device Management.
- Select the developer certificate in the "ENTERPRISE APPS" section.
- Press "Trust [Developer]".
- Select "Trust".
