Dependency that needs API key from the user

[atacan]

Hello, let's say I have an app where the user brings their own OpenAI key by inputting it in a TextField, and my dependency should use that key to call OpenAI endpoints.

pointfreeco website code uses an EnvVars dependency, but in that case the secret and dependency is defined inside the application. I want to make this OpenAI dependency a library, that's why I can have no idea where the library users put the API key.

Here is an example attempt. I'm trying to make a library using swift-openapi-generator.

I defined a Secrets dependency to be used in OpenAI dependency.

In the view, the changes made to TextField for the api key are saved to UserDefaults.

I thought about overriding that Secrets dependency when creating the ObservableObject. But it only works the first time it's called. I believe it caches it and it never calls UserDefaults.standard.string again, which I log with the print function in the next line.

The solution seems to be adding API key as argument to every variable of the dependency, but it didn't look right. I read about resetting the cache with $0 = DependencyValues(), but it also seems to be a one-time operation.

How should we do it?
