## Installation

### Swift Package Manager

[Swift Package Manager](https://swift.org/package-manager/) is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

> Xcode 26+ is required to build SnapKit using Swift Package Manager.

To integrate SnapKit into your Xcode project using Swift Package Manager, add it to the dependencies value of your `Package.swift`:

```swift
dependencies: [
    .package(url: "https://github.com/SnapKit/SnapKit.git", .upToNextMajor(from: "6.0.0"))
]
```

### Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate SnapKit into your project manually.

## Usage

### Quick Start

```swift
import SnapKit

class MyViewController: UIViewController {

lazy var box = UIView()

override func viewDidLoad() {
        super.viewDidLoad()

self.view.addSubview(box)
        box.backgroundColor = .green
        box.snp.makeConstraints { (make) -> Void in
           make.width.height.equalTo(50)
           make.center.equalTo(self.view)
        }
    }

}
```
