What do I want to do?

I build an App in which you can view different lectures. You are suppose to chose a lecture out of a Navigation View then click on Start Lecture and contine reading.

How is the App build up?

Page 0: MainMenuView - NavigationView that shows 5 Items (Lectures)

I have a [String : CustomUserInfo] dictionary. The key is an unique ID and the value is a custom object that contains user infos like displayName. The custom object CustomUserInfo conforms to Comparable and Hashable.

I am searching for a string and want only three key value pairs returned.

First I'm filtering the dictionary by displayName. This gives me a new dictionary with all key value pairs that are equal or larger then the string I am searching for.

Second I am sorting the dictionary by displayName, which gives me an array. Each element containing a key value pair.

If I got more than three elements in the array I remove the rest. That leaves me with an array of three elements.

The problem is, how do I convert this array back to a dictionary?

Alternative: is there a way to change the code in the closure after .filter to only return the three most relevant results? Skipping the whole round trip to an array and back to a dictionary.

I do need that because part of my code requires to access the CustomUserInfo objects by its key.

Here is a simplified playground version of my code:

I need to parse an XML file but unfortunately, I don't have any experience with that before.

Here is a shortened version of the xml file:
