Answer 1

Use a custom struct

struct Category {
   let name : String
   var items : [[String:Any]]
}

var sections = [Category]()

let itemsA = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
let itemsB = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]
let itemsC = [["Item": "item A","ItemId" : "1"],["Item": "item B","ItemId" : "2"],["Item": "item C","ItemId" : "3"]]


sections = [Category(name:"A", items:itemsA), 
            Category(name:"B", items:itemsB), 
            Category(name:"C", items:itemsC)]

func numberOfSections(in tableView: UITableView) -> Int {
    return self.sections.count
}

func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return self.sections[section].name
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    let items = self.sections[section].items
    return items.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "StoreCell") as! UITableViewCell
    let items = self.sections[indexPath.section].items
    let item = items[indexPath.row]
    print(item["ItemId"] as? String)

    return cell
}

You can still improve the code if you are using a custom struct also for the dictionaries.
