macOS Internals

Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.

You've got two main options:

	@propertyWrapper struct IgnoreEquatable<Value>: Equatable {
	var wrappedValue: Value

	static func == (lhs: IgnoreEquatable<Value>, rhs: IgnoreEquatable<Value>) -> Bool {
	true
	}
	}

	@propertyWrapper struct CustomEquatable<Value>: Equatable {
	var wrappedValue: Value

	func quickSort(_ array: [Int]) -> [Int] {
	guard array.count > 1 else { return array }

	let pivot = array.first!
	var left = [Int]()
	var right = [Int]()

	for i in 1..<array.count {
	let value = array[i]
	if value < pivot {

	#!/bin/bash
	if [ -f ~/Library/KeyBindings/DefaultkeyBinding.dict ]; then
	echo "~/Library/KeyBindings/DefaultkeyBinding.dict already exists"
	exit -1
	fi

	mkdir -p ~/Library/KeyBindings
	cat << EOF > ~/Library/KeyBindings/DefaultkeyBinding.dict
	{
	"₩" = ("insertText:", "\`");

	extension String {
	/// Returns a new string made by replacing all HTML character entity references with the corresponding character.
	/// decode per unicode because ;️(utf-16 `\u003b\ufe0a`) but i need find ;(utf-8 `\u003b`).
	/// - Returns: decoded string
	func decodingHTMLEntities() -> String {
	let scalars = unicodeScalars

	// https://leetcode.com/problems/set-matrix-zeroes/
	class Solution {
	func setZeroes(_ matrix: inout [[Int]]) {
	if matrix.isEmpty {
	return
	}
	var points = [(Int, Int)]()
	let rows = matrix.count
	let columns = matrix[0].count

	// 이렇게 실행하면 asset-info.json 파일 안에 Assets 저장 정보가 나타남
	> xcrun --sdk iphoneos assetutil --info Assets.car > asset-info.json
