Computer science theory

Что такое инвариант цикла?
Что такое сложность алгоритма? O(n) нотация. O(???) для операций с NSArray, NSDictionary, запрос в БД (индексированный VS. неиндексированный)
CS data structures (linked list, binary tree, array)
Различия аутентификации, авторизации

	Storyboard :
	+ видна структура приложения (переходы)
	+ визуально верстаешь
	- частые и трудно решаемые merge conflict
	- тормоза xcode когда “всё в одном файле” (сюрприз! можно иметь несколько storyboard в одном прожекте)

	Xib :
	+ визуально верстаешь
	+ merge conflict реже
	+ Нет тормозов, ибо “1 xib - 1 screen”
