# id(_:)

Binds a view’s identity to the given proxy value.

## Declaration

```swift
nonisolated func id<ID>(_ id: ID) -> some View where ID : Hashable

```

## Discussion

Discussion When the proxy value specified by the id parameter changes, the identity of the view — for example, its state — is reset.
