The document discusses Swift and its development. It mentions Swift's libraries being available on GitHub, the Swift package manager, integrated debugging with LLDB, and how the Swift community communicates and contributes to the language through mailing lists, GitHub, and bugs.swift.org. Communication and contribution is overseen by a core team and committers.

“Object-oriented programming is eliminated
entirely from the introductory curriculum, because
it is both anti- modular and anti-parallel by its very
nature, and hence unsuitable for a modern CS
curriculum. A proposed new course on object-
oriented design methodology will be offered at the
sophomore level for those students who wish to
study this topic.” - Robert Harper, professor at CMU

13. 순수한 함수
★ 부작용(side-effect)이 없는 함수
★ 변경 불가한 데이터 (Immutability)
★ 참조 투명성 (referential transparency)
★ 게으른 평가 (lazy Evaluation)
★ 타입 클래스 (type class)
★ 고계 함수 (high-order function)

I can do all
that with structs
and enums.

27. Value Type vs. Reference Type
Call by value, Call by reference

28. Classes That Do Not Contain References
Reference Reference Reference Reference
Point Point Point Point
Array
class Point {
var x, y: Float
}
}
for p in array {
...
var array: [Point] = ...

29. var x, y: Float
struct Point {
Structs That Do Not Contain References
Array
for p in array {

...
var array: [Point] = ...
Point Point Point Point
}
All reference counting operations eliminated
