In the name of God, please allow initializing GeneratedContent from an array of key-value pairs. It’s literally the same thing KeyValuePairs uses internally, but it would let us initialize structure-like GeneratedContent from dynamic data without resorting to unsafeBitCast hacks.

For anyone looking for a temporary solution, you can (but probably shouldn't) do this:

struct DynamicKeyValuePairs<K, V> {
    let _elements: [(K, V)]

    init(_elements: [(K, V)]) {
        self._elements = _elements
    }
}

let kvp = unsafeBitCast(
    DynamicKeyValuePairs(_elements: properties),
    to: KeyValuePairs<String, any ConvertibleToGeneratedContent>.self
)

To explain a little why this might be useful:

– It allows for more use cases of Foundation Models from non-native frameworks like Flutter and React Native.

Here is an example of how you can create a bridge from Flutter to Foundation Models, with Dart Tools support.

– It also opens up use cases like MCP servers, where tools are dynamically fetched from some config/server. Though not very usable given current model constraints — but still.
