Create demos to show iOS IDM SDK in action

What
Prepare a demo showcasing the using the ios IDM SDK.
Why
We want to be able to show the user that the IdM SDK is integrated after following the steps in the documentation
Let's also show the functions that have been implemented by this EPIC.

If at the time this ticket is processed, the mobile security ios app is updated to use the IOS IDM SDK, we should aim to use the app (as it will show the right dependency setup). However, if that is not the case, the example app can be used to produce the demo.

It should be similar to the video we create for the android IDM sdk. See https://issues.jboss.org/browse/AGDROID-674 for the things we should cover in the video.
