The easiest way to do this would be to use xcode automatic mobileprovisions generations.
1. disable any ios_enable_XXX_extension in ios/build/chrome_build.gni (it would make things more difficult).
2. update the group prefix in build/config/ios/ios_sdk.gni
3. generate xcode project by running : python ios/build/tools/setup-gn.py
4. build : ninja -C out/Debug-iphoneos chrome
5. open the project out/build/all.xcworkspace in xcode
6. in the chrome project settings, enable "automatically manage signing" and select your certificate
7. in Build Settings, set the Info.plist path for debug to point to out/Debug-iphoneos/Chromium.app/Info.plist
8. press run for the chrome project
9. enjoy
On 7 I get error Cycle error
I try run with automatic sign in, I try with create profile i always get 1 error.
In my device I don't have certificates or something else in VPN & Device Management
Maybe you have some video instruction how to run Chromium in device?
Thank for answer.
