Помогите разобрать на части [[String]]

#1

Всем привет. Парни, нужна помощь. Гуголь уже отрекся.
Есть массив типа такого:
[[“1”, «Section 1"], [“1.1”, «Item 1.1"], [“1.1.1”, «subItem 1.1.1"], [“1.1.2”, “subItem 1.1.2”], [“1.1.3”, “subItem 1.1.3”], [“1.1.4”, “subItem 1.1.4”], [“1.1.5”, “subItem 1.1.5”], [“1.1.6”, “subItem 1.1.6”], [“1.1.7”, “subItem 1.1.7”], [“1.2”, “Item 1.2”], [“1.2.1”, “subItem 1.2.1”], [“1.2.2”, “subItem 1.2.2”], [“1.2.3”, “subItem 1.2.3”], [“1.2.4”, “subItem 1.2.4”], [“1.2.5”, “subItem 1.2.5”], [“1.2.6”, “subItem 1.2.6”], [“1.2.7”, “subItem 1.2.7”], [“1.2.8”, “subItem 1.2.8”], [“1.2.9”, “subItem 1.2.9”], [“1.2.10”, “subItem 1.2.10”], [“1.2.11”, “subItem 1.2.11”], [“1.2.12”, “subItem 1.2.12”], [“1.2.13”, “subItem 1.2.13”], [“1.3”, “Item 1.3”], [“1.3.1”, “subItem 1.3.1”], [“1.3.2”, “subItem 1.3.2”], [“1.3.3”, “subItem 1.3.3”], [“1.3.4”, “subItem 1.3.4”], [“1.3.5”, “subItem 1.3.5”], [“1.3.6”, “subItem 1.3.6”], [“1.3.7”, “subItem 1.3.7”], [“1.3.8”, “subItem 1.3.8”], [“1.3.9”, “subItem 1.3.9”], [“1.3.10”, “subItem 1.3.10”], [“2”, “Раздел 2”], [“2.1”, “Item 2.1”], [“2.1.1”, “subItem 2.1.1”], [“2.1.2”, “subItem 2.1.2”], [“2.1.3”, “subItem 2.1.3”], [“2.1.4”, “subItem 2.1.4”], [“2.1.5”, “subItem 2.1.5”], [“2.1.6”, “subItem 2.1.6”], [“2.1.7”, “subItem 2.1.7”], [“2.1.8”, “subItem 2.1.8”], [“2.1.9”, “subItem 2.1.9”], [“2.1.10”, “subItem 2.1.10”], [“2.1.11”, “subItem 2.1.11”], [“2.1.12”, “subItem 2.1.12”], [“2.1.13”, “subItem 2.1.13”], [“2.2”, “Item 2.2”], [“2.2.1”, “subItem 2.2.1”], [“2.3”, “Item 2.3”], [“2.3.1”, “subItem 2.3.1”], [“2.4”, “Item 2.4”], [“2.4.1”, “subItem 2.4.1”], [“2.4.2”, “subItem 2.4.2”], [“2.4.3”, “subItem 2.4.3”], [“2.4.4”, “subItem 2.4.4”], [“2.4.5”, “subItem 2.4.5”], [“2.4.6”, “subItem 2.4.6”], [“2.4.7”, “subItem 2.4.7”], [“2.5”, “Item 2.5”], [“2.5.1”, “subItem 2.5.1”], [“2.5.2”, “subItem 2.5.2”], [“2.5.4”, “subItem 2.5.3”], [“2.5.5”, “subItem 2.5.4”], [“2.5.6”, “subItem 2.5.5”], [“2.5.7”, “subItem 2.5.6”], [“2.5.8”, “subItem 2.5.7”], [“2.5.9”, “subItem 2.5.8”], [“2.5.10”, “subItem 2.5.9”], [“2.6”, “Item 2.6”], [“2.6.1”, “subItem 2.6.1”], [“2.6.2”, “subItem 2.6.2”], [“2.6.3”, “subItem 2.6.3”], [“2.6.4”, “subItem 2.6.4”]]

Не понимаю как можно его отсортировать (либо в структуру, либо в отдельные массивы).
Цель: есть VC1 с tableView где отображается sections и Items. Тапаем на ячейку с Item и переходим на VC2 где tableView с subItem. Пожалуйста, объясните, как лучше решить эту задачу. Поменять индексы (как 2.4.7) я не могу, и точное число элементов массива - непредсказуемо. Благодарю. Хороших выходных.
