“Untrusted App Developer” message when installing enterprise iOS Application

Question

I\'m developing an enterprise application. When I was testing it in iOS8 beta I saw the following alert view:

Untrusted App Developer
Do you trust the develo         


        

Answer 1

If you push it out through MDM it should auto-trust the application (https://support.apple.com/en-gb/HT204460), but it still has to verify the certs etc with Apple to ensure they've not been revoked etc i presume. I had this message preventing the application from launching and it was only when the proxy information was configured so it i could use the internet that it went away after a couple more launch attempts.

Answer 2

In iOS 9.3.1 and up: Settings > General > Device Management

Answer 3

Today, I was testing this with iOS 9 Beta and found the solution.

To solve it, go to:

1. Settings -> General -> Profiles [Device Management on iOS 10]
2. Under ENTERPRISE APP, choose your current developer account name.
3. Tap Trust "Your developer account name"
4. Tap "Trust" in pop up.
5. Done

Answer 4

For iOS 13.6

Go to settings -> General -> Device Management -> Click on Trust « Apple Development » -> Click on the red trust button and you’re all set!
