this APP gets published only to internal App Store.
Just FYI, this doesn’t make a difference. Enterprise apps are expected to follow the same rules as App Store apps, and certainly DTS supports them in the same way.
As part of this APP, is it possible to implement functionality to dynamically or based on user action, update iOS Device Wallpaper
No.
Lock-screen image?
No.
In situations like this your only option is to file an enhancement request (ER) for the APIs you’d like to see. I do, however, want to set some expectations here: Settings like this are normally under the user’s control, so requests for programmatic control often get rejected.
Given that you’re working in an enterprise environment one alternative is to file an ER for a way to set this stuff like MDM. There are all sorts of things you can do via MDM that you can’t do programmatically.
Share and Enjoy
