## Coding convention
set of guidelines for a specific programming language that recommend programming style

### Swift Style Guide

- [Swift Style Guide](https://github.com/linkedin/swift-style-guide)

### Swift Lint
The way of force you to adapt coding convention 
>otherwise project build will **FAILED**
- [Swift Lint](https://github.com/realm/SwiftLint) apply for all project:+1:
```swift
if which swiftlint >/dev/null; then
  swiftlint
else
  echo "error: SwiftLint not installed, download from https://github.com/realm/SwiftLint"
  exit 1
  fi
```
put .yml file into root folder and apply following code in Build Phases

**You can modify(delete) SwiftLint Option with opening .yml file**

## Design Pattern
Design pattern is

Check [this](https://refactoring.guru/design-patterns/swift) website for design pattern in Swift

### Delegate Pattern

```swift
weak var delegate: SomeProtocol?
```

### Singleton Pattern


```swift
class SingletonPattern {
    static let manager = SingletonPattern()
    
    private init() {}
}
```

### Observer Pattern


## Code Structuring

### MVC

<img src="https://github.com/jphong1111/Useful_Swift/blob/main/Images/MVCModel.png">

### MVVM

##### MVC vs MVVM

<img src="https://github.com/jphong1111/Useful_Swift/blob/main/Images/MVVMvsMVC.png">

M -> Model – Which holds the application data

V –> View – It displays the data that is stored in model. These are visual elements through which a user interacts. These are subclasses of UIView

VM –> View Model – Transform model information/data and it interacts with controller or view to display those informations.

C –> Controller class – It will be there but the responsibility of view business logic has been removed and give to view model

## Helper

You can check the file in the follow link

- [Email, Message, Call](https://github.com/jphong1111/Useful_Swift/blob/main/Helper/ConversationManager.swift) 
### Usage
import MesaageUI first

```swift
import MessageUI
```

Then use it

```swift
    lazy var manager = ConversationManager(presentingController: self, mailDelegate: self, messageDelegate: self )
    
    func sendEmail() -> MFMailComposeViewController {
        manager.sendEmail(feedback: MailFeedback(recipients: ["abcd@example.com"], subject: "Sample", body: "Write body"))
    }
    
    func sendMessage() -> MFMessageComposeViewController {
        manager.sendMessage(feedback: MessageFeedBack(recipients: ["1111111111"], body: "Type here"))
    }
    
    func call() {
        manager.makeCall(number: "1111111111")
    }
```

## API

### Various API Site
- [rapidAPI](https://www.rapidapi.com)

## JSON
JSON is a language-independent data format
> Which is relative with **KEY - VALUE** pair
```json
{
    "main": [
        {
            "title": "example1",
            "body": "body1"
        },
        {
            "title": "example2",
            "body: "body2"
        },
    ]
}
```
### JSON parser extension for Chrome
This extension makes JSON more structable
[JSON parser pro](https://chrome.google.com/webstore/detail/json-viewer-pro/eifflpmocdbdmepbjaopkkhbfmdgijcc) **FREE** :+1:

### JSON Decoding

### JSONSerialization
