Web apps are fine, I believe the issue is Apple wants to prevent apps from updating their Objective-C code. Anything run by WebKit is fine. From the Rollout page linked above:
> With Rollout’s SDK you can update and modify your Objective-C methods with logic written in JavaScript so we’re good on the first condition.
> With Rollout’s SDK you can update and modify your Objective-C methods with logic written in JavaScript so we’re good on the first condition.
I think that is the problem with Rollout.
