# Swift-Intersection

Extensible records / intersection type in Swift.

```swift

struct S1 {

    var value1: Int

}

struct S2 {

    var value2: Bool

}

let intersection = Intersection(S1(1), S2(true))

// Type of `intersection` works similar to `S1 & S2` (intersection type) in TypeScript), i.e.:

//

// struct S1_And_S2 {

//     var value1: Int

//     var value2: Bool

// }

XCTAssertEqual(intersection.value1, 1)

XCTAssertEqual(intersection.value2, true)

```
