How can I show data on a tableview with its origin from a struct and one extra cell for adding action?
All data(invoice and items) is fetched from a server and it works fine.
If I add a print, it shows all data on the console.
[Invoice.InvoiceItem(invoice_detail_id: 13, description: oi, unit_price: 2, quantity: 1), Invoice.InvoiceItem(invoice_detail_id: 14, description: re, unit_price: 3, quantity: 2), Invoice.InvoiceItem(invoice_detail_id: 15, description: fsdf, unit_price: 4, quantity: 3)]
The problem is that it doesnt populate on the tableview. I tried adding or subtracting 1 without success.
Also, there is one more cell, that is not for items, but for adding a new item, and always being the last cell or the only one when there is no item.
tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) seems to be called only once... where in fact it should be 4 (3 items plus add cell)

invoiceget set to something other than nil?
