Whilst going through Apple’s guide “Storing Keys in the Keychain” I noticed one thing.

The queries are of type [String: Any] , so I want to test the creation of the query.

I’ll need to test the keys and values of type String and Any are created correctly, respectively.

I’ll need to compare Any value types. :(
