# subscript(dynamicMember:)

Accesses an intent parameter by name, for comparison with a known value.

## Declaration

```swift
subscript<T>(dynamicMember identifier: String) -> T where T : IntentValueConvertible { get throws }
```

## Overview

Overview The code below shows the syntactic sugar and the equivalent, desugared, subscript syntax. try intent.someName == "My Name" try intent[dynamicMember: "someName"] == "My Name" If the property’s value isn’t an instance of the type T, this subscript throws an error.
