github "SnapKit/SnapKit" ~> 5.0.0
```
Run `carthage update` to build the framework and drag the built `SnapKit.framework` into your Xcode project.
### 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 11+ 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: "5.0.1"))
]
```
### Manually
If you prefer not to use either of the aforementioned dependency managers, you can integrate SnapKit into your project manually.

### Playground
You can try SnapKit in Playground.
**Note:**
> To try SnapKit in playground, open `SnapKit.xcworkspace` and build SnapKit.framework for any simulator first.
