## Roadmap
## What's new
### What's new in 1.2.0
## Installation
### SwiftPackageManager
### Manual installation
If you want to install SnackView manually, just drag **Sources** folder into your project.
## Usage
### Create your custom SnackView alert
SnackView includes some default UI elements as Button, Label and other complex UI.
The first step is to create an array of SVItem. SVItem is the class of every element that SnackView can include within it.
Here an example of simple SnackView alert:
```swift
class MyCustomClass: UIViewController {
override func viewDidLoad() { }
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
// Present the SnackView
let dataSource = self
SnackView(with: dataSource).show()
}
}
// MARK: - SnackViewDataSource Section
extension MyCustomClass: SnackViewDataSource {
func titleFor(snackView: SnackView) -> String {
return "What's New"
}
func cancelTitleFor(snackView: SnackView) -> String? {
return "Dismiss"
}
func itemsFor(snackView: SnackView) -> [SVItem] {
let descriptionItem = SVDescriptionItem(withDescription: "In this last release of SnackView we...")
let imageItem = SVImageViewItem(withImage: UIImage(named: "hat_is_new")!,
andContentMode: .scaleAspectFill)
return [descriptionItem, imageItem]
}
}
```
------

```

andText: "Lorem ipsum dolor sit amet...")
```
***

# Create custom SVItems
#### You can create custom items subclassing SVItem class.
Here below an example.
```swift
import UIKit
import SnackView
//Create a subclass of SVItem
class SVCustomItem: SVItem {
//Pass all parameters in init method to customize your SVItem
init(withColor color: UIColor) {
super.init()
//Add an UIView
let customView = UIView()
customView.translatesAutoresizingMaskIntoConstraints = false
customView.backgroundColor = color
self.addSubview(customView)
//Add UIView contraints
let vConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:|-[customView(70)]-|", options: [], metrics: nil, views: ["customView":customView])
let hConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:|-[customView]-|", options: [], metrics: nil, views: ["customView": customView])
self.addConstraints(vConstraints + hConstraints)
}
required public convenience init?(coder aDecoder: NSCoder) {
self.init(coder: aDecoder)
}
}
```
