Can I install both ready for sale and beta test flight versions?

Question

In iTunes Connect, I have a Ready for sale version, available for public download. Also, I have a beta versión with some improvements on design, etc.

May I have installed both, production and beta versions, at the same time on one device to test the beta and compare it with the production released?

Answer 1

No, I don't think that's possible. The app id (com.company.appID) must be unique, iOS won't let you install two applications with the same app id next to each other.

You could have a second App in iTunesConnect for tests, and send the same application with the only change being in the app id.
