In order to fix this we will have to modify starting at line 195

local files = fileManager:contentsOfDirectoryAtPath_error_(name.path, nil) if files ~= nil then

files currently contains the file names of items in name.path (e.g., Main.lua, Info.plist, File.lua)

We will need it to contain subfolders as well: [Main.lua, subfolder/File.lua, Info.plist, ...]

Context after this line

            -- Test if it's a directory
            local fileManager = objc.NSFileManager.defaultManager
            local files = fileManager:contentsOfDirectoryAtPath_error_(name.path, nil)
            if files ~= nil then
                
                local bufferOrder = {}
                for i = 1, #files do
                    if files[i] == "Info.plist" then
                        local plist = objc.NSDictionary:dictionaryWithContentsOfFile_(name.path .. "/Info.plist")
                        bufferOrder = plist["Buffer Order"]
                    end
                end
                
                if #bufferOrder > 0 then
                    local orderMap = {}
                    for i, name in ipairs(bufferOrder) do
                        orderMap[name] = i
                    end

                    table.sort(files, function(a, b)
                        -- Use the mapped order, defaulting to a high value to sort unmatched files last
                        local aOrder = orderMap[a] or #bufferOrder + 1
                        local bOrder = orderMap[b] or #bufferOrder + 1
                        return aOrder < bOrder
                    end)
                end

I've implemented a fix for this issue that adds recursive folder support to require.lua.

The implementation adds a recursive enumeration function that walks through subdirectories and includes files with their relative paths (e.g., subfolder/File.lua). This allows:

• Organizing code in subdirectories within projects
• Referencing files in subfolders via Buffer Order in Info.plist
• Maintaining full backward compatibility with existing projects

A PR has been created with the fix. The branch fix/issue-343-folder-support-in-require is ready for review.
