Deploying older versions of iOS app

Question

Perhaps I made a mistake, but when I finished working on v1.1 of my app, I merged it into the master branch in XCode and removed the 1.0 branch. Now, working on my v1.11 branch, I would like to test the migration from 1.0 to 1.11. Though I still have the binary saved.

How can I deploy my binary of version 1.0 on to the simulator and my test device?

And should I have kept the v1.0 branch hanging around indefinitely for this kind of scenario, or was I right to remove it once the code was merged back in to the master branch?

Any advice on best practice for handling this kind of thing?

Answer 1

Further reading indicates that the simplest way to test updates is to deploy the old .ipa using iTunes. This assumes you have the binary archived from the time of submission.
