Basically I would like to display every tobacco and all the available hookahs in a UITableView, based on if the tobacco segment or the hookah segment is pressed. First you should see the brand and after that the "products" (like all tobaccos or hookahs).
So now, how exactly should the firebase database then look like? Because every product (hookah, tobacco) should have a "name", "brand", "rating" and "description".
The second question: How would I receive all these informations in my tableview by code? For now I am working with the following structure of sections for my tableview which is dependent on the var p if it is 0 or 1. Then it selects the section on index 0 or 1 (based on which segment is clicked).

var sections = [[Section(brand: "7 Days", products: ["Tabak1", "Tabak2", "Tabak3"], expanded: false),

                 Section(brand: "Zomo", products: ["Tabak1", "Tabak2", "Tabak3"], expanded: false)],

                [Section(brand: "Aeon", products: ["Shisha1", "Shisha2", "Shisha3"], expanded: false),

                 Section(brand: "Vendetta", products: ["Shisha1", "Shisha2", "Shisha3"], expanded: false)]]

What the tableView looks like when its expanded

I would really appreciate any answer to any of the two problems.
Thank you!

If you are simply reading data and will never query for anything it's pretty straightforward

root

   all_data

      data_0 //created with .childByAutoId

         brand: "7 days"

         products:

            "Tabak1": true

            "Tabak2": true

       data_1

         brand: "Zomo"

         products:

            "Tabak1": true

            "Tabak2": true

       data_3

         brand: "Aeon"

         products:

            "Shisha1": true

            "Shisha2": true

however, this will lead to issues* if for example you want to query for all brands that have Tabak2 products. So here's an alternative that would enable you to easily determine the brand nodes that have Tabak2

root

   brands

      brand_0

         brand: "7 days"

      brand_1

         brand: "Zomo"

      brand_2

         brand: "Aeon"

   products_by_brand

      brand_0

         "Tabak1": true

         "Tabak2": true

      brand_1

         "Tabak1": true

         "Tabak2": true

      brand_2

         "Shisha1": true

         "Shisha2": true

And if you want to be super cool then here's a structure that cross references all products and brands which would allow for a variety of queries and allow you to link single products back to multiple brands and vice-versa

root

   brands

      brand_0 //created with .childByAutoId

         brand: "7 days"

         product_0: true //products should probably be in a child node

         product_1: true

      brand_1

         brand: "Zomo"

         product_0: true

         product_1: true

   all_products

      product_0

         name: "Tabak1"

         brand_0: true

         brand_1: true

      product_1

         name: "Tabak2"

         brand_0: true

         brand_1: true

*this can actually be accomplished via a deep path query

brands -> products -> tobacco -> uniqueId -> name, rating and description

               -> hookah -> uniqueId -> name, rating and description

I'm not sure if you need to include the brand in the product details since that would be the main parent.
Hope this helps :)
