# Swift 讀書會 Week 1

4+
* Chp 2 - Playground 教學
5+
* Chp 3 - 第一個APP 與Xcode環境認識
6+
* Chp 4 - 第一個APP的運作原理

# 操作環境
11+
12+
* OS X 10.11.5
13+
* Xcode 7.3.1
14+
* Swift 2.2 (Xcode 7.3.1 Default)
15+

# Chapter 1
19+
20+
工具準備：
21+
1. 一台Mac
22+
2. 將你的Apple id[註冊](https://developer.apple.com/register/)為開發者帳號（如果你想在實機上run app）
23+
3. 從App Store 安裝Xcode最新版（此文件中為7.3.1）
24+
4. 如果想上架App，才需要Devloper program（一年 $99 美金）
25+

# Chpater 2
29+
30+
從Objective C說起：
31+
```
32+
[self transitionFromViewController: firstVC toViewController: secondVC duration: 1.5 options: UIViewAnimationOptionRepeat animations: ^() { // do animation } completion: nil];
33+
```
34+
* 語法起源於「small talk」
35+
* 超長的命名
36+
* **必須**宣告每個變數與常數的型態
37+
* 屬於「動態語言」(OS 10.5 之後)
38+
39+
---
40+
41+
# Swift的野望
42+
43+
* 追求更快，更現代，更安全的程式語言
44+
* 是一個「靜態語言」(Statically Typed Language)
45+
* 不一定要宣告變數型態(Type Inference)
46+
* 吸收JS, Python 等現代語言的優點
47+
* Optional的觀念，用於處理null（在Swift和OC用 `nil` )
48+

# 語法比一比
52+
53+
```objc
54+
const int count = 10;
55+
double price = 23.55;
56+
57+
NSString *firstMessage = @"Swift is awesome. ";
58+
NSString *secondMessage = @"What do you think?";
59+
NSString *message = [NSString stringWithFormat:@"%@%@", firstMessage, secondMessage];
60+
61+
NSLog(@"%@", message);
62+
NSLog([firstMessage isEqualToString: secondMessage] ? @"YES": @"NO");
63+
```
64+
65+
```swift
66+
let count = 10
67+
var price = 23.55
68+
69+
let firstMessage = "Swift is awesome. "
70+
let secondMessage = "What do you think?"
71+
var message: String = firstMessage + secondMessage
72+
73+
print(message)
74+
print(firstMessage == secondMessage)
75+
```

# 通用的命名法則
80+
81+
* `UIViewController`: UI (framework縮寫，此為UIKit) + ViewController（型別名稱）
82+
* 型別命名使用 upper camel case，例：`NSString`
83+
* property命名使用 lower camel case，例：`firstMessage`
84+

# 可變與不可變
88+
89+
In Objectiv-C:
90+
91+
* `NSArray` v.s. `NSMutableArray`
92+
* Mutable 代表本身可變
93+
94+
In Swift：
95+
96+
* let：常數不可變（但若指向一個reference type對象，則對象內成員可變）
97+
* var：本身為可變
98+
99+
```swift
100+
let str = "abcd"
101+
str = "efgh" // 此行Compiler會丟error警告
102+
```
103+
104+

105+

# Playground
107+
108+
* 顧名思義，試語法的地方
109+
* 類似Python或Javascript的 shell和console
110+
* 每打一個字就compile & run
111+
* [Demo範例檔]()
112+
* [Swift 2 basic tutorial 範例](https://www.dropbox.com/s/8kgxig3cgr4z2v4/SwiftIntro.zip?dl=0)

# 小撇步
117+
1. 在變數上按住「alt + 左鍵」點擊變數，會出現變數型別與宣告處
118+
2. 在變數上按住「command + 左鍵」點擊變數，會跳到宣告變數的地方
119+
3. 游標停留在型態宣告的地方，打開右側Utilites欄位，會出現Quick Help並顯示文件

150+
151+
* Target: `ViewController`
152+

# self
157+
158+
* 代表現在（本身）這個instance 或 object
159+
* 在Swift中，大多時候可以省略（但要清楚到底是 property 或 local variable)
160+
* Capturing: 在Closure裡，不可以省略self（compiler會叫），另需特別處理以免發生retain cycle（closure時再說明）

# 執行App
165+
166+
1. compile: Swift為靜態語言，大多數行為在此確定，將code編譯為machine code
167+
2. package: 其實也算compile的一個階段，將各種資源(images, text)
168+
3. run: 在simulator上執行，程式的進入點為 `AppDelegate.swift`
