Hello! I am using a Mac Swift Playground 3.4.1, and want to save data inputted on one playground page to be used across the other pages. I read in the Apple Documentation to use PlaygroundKeyValueStore, but when I put it into my playground page (after importing Playground Support), I get the error in above title. Is this function deprecated? Since it seems like it still worked in 2020.

Apple Documentation for this class:

Based on other descriptions in the doc, the code sample is a bit outdated.

It should be something like this:

Code Block // Store a value.
PlaygroundKeyValueStore.current["animal"] = .string("Llama")
// Retreive that same value.     
var theAnimal: String? = nil
if let keyValue = PlaygroundKeyValueStore.current["animal"],
   case .string(let animalType) = keyValue {
    theAnimal = animalType
}
