Is there a way to have both the app store version and the TestFlight version installed at the same time on one iPhone? Can we release the ad-hoc version of the test app via the TestFlight? How to use FastLane to publish a test ad-hoc version of the app in the TestFlight?
You need to have different bundleID (mean different app) to install at same time. Other wise app will replace existing app no matter what process you used to download application.
