Adding a Framework on iOS in runtime

At first, I will describe my use-case on why I need to add the framework at runtime on iOS.

Let's say I have an app on iOS device. The app requires some 3rd party frameworks to add some external features to it. Now, the features are many. So, the required number of frameworks will be many too. An user may not need lots of features. Just a small set of features. Plus, lots of framework will require a lot of space. The application will be huge in size.

For an example, an user needs only 1 feature. The application provides 100. So, all the other frameworks will definitely be unnecessary.

So, the solution would be to download the frameworks and the necessary files on demand from an online repository, link them on runtime and use them. This would mean the application size would be very small and not bulky with unnecessary stuff.

But does iOS provide that? I have to add an external framework and the necessary files that is not on the app use them on runtime.

Is this possible? Can anyone provide me with some resources on how I can do that?

I have seen some resources on SO and some other sites. The results are not so helpful.
