How to create an ipa that can be trust on both ios10 and ios12 using Apple Developer Account

Question

I'm using xcode 10 and i have an app created using ionic framework that can be installed via OTA, this app is signed using Apple Developer Account (not Enterprise), ios 10 can download and install the app and then later on trust the certificate in Device Management (Distributed by automatic signing). The problem is when it is downloaded by ios 12, the app is greyed out and when you go to the settings there is no Device Management.

I've tried several method like Sign up the device to apple beta software program and install profile. I'm think that when the installed app is distributed by enterprise account (in-house distribution), the profile of that app will show (correct me if i'm wrong). So i tried to create a provisioning profile and registers the device UDID (Ad-hoc distribution), after that the app is successfully installed, but i need to install the app without registering any device UDID.

Because ios10 can trust the app on device management without registering the device UDID, Is there a way for me to create an ipa with a "public provisioning profile like" using Apple Developer Account?

I'm not sure the purpose of you doing so. If it's for testing purposes, the easiest way is to enable automatic signing in Xcode and run the app to your device on both iOS 10 and iOS 12, this will automatically add the device UDID to your dev account. (although the correct way is to get the UDID from iTunes and add the UDID to your dev account, which is tedious)

Later on, you can build the IPA and install the IPA to those devices.

Hope it helps.
