PickerView using data set from another class keeps returning empty

Hi, first post here so not too sure on the format but I've got a problem that for the life of me I just cannot solve at all. Basically I've got a picker view that should be filled with data that the user has entered on another form, however, the picker view keeps on returning empty. So, to put it into context for my project, the user can create multiple profiles and then be able to select what profile the medication is for, using a picker view but again the picker view just returns empty. Any help you are able to provide would be greatly appreciated.

This question is better asked at Apple Developer Forum.

For a starter, you could try the make a minimal example that is small enough to copy&paste and does compile. At least, people will know what you’re talking about, and you may also figure it out in the process.
