Cannot assign value of type 'Binding<[String]>' to type '[String]'

Thanks @mikaelacaron! Have you seen any sample projects similar to what I laid out in my previous post that I could possibly learn from? My goal is to structure it like a relational database like how you mentioned in a previous thread about having a foreign key relationship (it’s essentially the same problem on both threads that I’ve been trying to work out).

@mikaelacaron

Properties of the PeopleProfile it should only have the id property of the person that’s saved, so it’s actually a list of UUID . When you retrieve the data, you connect the data together (called joining) from the PeopleProfile

This is what’s called a foreign key relationship in relational databases.

Your entities should look like this:

• PeopleProfile : stores all the people
  • id as UUID
  • name as String
• Groups : stores all the groups and what people are in that group
  • GroupNumber as Int , this shouldn’t be an “id” because id usually means something that’s unique, which in your example it’s just denoting that someone is in group 1
  • PeopleProfileId as UUID , this is the UUID of the PeopleProfile

When you fetch the data, you first fetch everyone from Groups with a specific GroupNumber , and then given that you have all the ids of the people. Next loop through those people and fetch all their information. (There might be a way to combine these, but I’m not sure what it is in CoreData). Haha I know what it would be writing normal SQL (which is used with relational databases)
