Using a local Realm to load a row of properties as a selectable row for a Picker

I am looking for someone that has connected a local Realm to provide an array of properties such as keyID and three string properties as a selectable row in a Picker. This will be used to record the selected key value for future use in another realm by another SwiftUI view looking for which record to be opened for property display in the UI. The analogy I am using is to save the keyvalue of one Realm based on the user use of the Picker, so it can be called later by another Realm query.
