Good morning all,

I am working on one of my programs that I had setup under the old NavigationView and was using a navigation style of stack. I am trying to make it work with the new NavigationSplitView so I can better utilize the screen realestate. I am getting this error and not sure why?

error build: Initializer 'init(_:rowContent:)' requires that '[Program]' conform to 'Identifiable'

I am having some trouble and I a don't know why? Under the current stack when I display the programs its sectioning them out under Scheduled & Completed. Heres the code that I use:

Sectioning what comes back from this function is an [[Program]]

    func sectionedPrograms(_ searchString: String, howManyToShow: Int) -> [[Program]] {
        // Reduce by filtering on searchTerm
        let filteredList = programs.filter { searchString.appearsIn($0.name) || searchString.appearsIn($0.date.dateText(style: .medium)) }

        // Separate out by statusText
        let dictionaryByStatus = Dictionary(grouping: filteredList, by: { $0.statusText })

        // Return the array of dictionary entries. There will be two. If both are nil, the result
        // is an empty list - and it should be.
        if let completedPrograms = dictionaryByStatus[Status.completed] {
            // If we are here then we are returning only the first howManyCompletedProgramsToShow
            let programs = Array(completedPrograms.prefix(howManyToShow))
            return [dictionaryByStatus[Status.scheduled], programs].compactMap { $0 }
        }

        return [dictionaryByStatus[Status.scheduled]].compactMap { $0 }
    }

        } detail: {
            if let program = selectedProgram {
                ModifyExistingProgramView(program: program, dataManager: dataManager)
            }
        }

I would appreciate any help or suggestions anyone has.

Thanks Taz
