方便地在 Swift 中利用 Objective-C 关联对象。

## 集成

使用 Swift Package Manager 或手工导入。

You can also use [GitHub source](https://github.com/b9swift/AssociatedObject).

## 使用

定义扩展属性可以像下面这样，不仅支持 Objective-C 对象，各种 Swift 类型也支持。

```swift
import B9AssociatedObject

private let fooAssociation = AssociatedObject<String>()
extension SomeObject {
    var foo: String? {
        get { fooAssociation[self] }
        set { fooAssociation[self] = newValue }
    }
}
```
