Apollo iOS 2.0 Migration and parsing data

Prior to 2.0 version, GraphQLResponse had a few helpful public functions like parseResponse that could be used by the consumers, but now they seem to be removed. I didn’t see any info on these in the migration guide, is there any info on how to migrate, when those parsing functions have been used?

We don’t use ApolloClient, but rather were using helpers like parseResultFast() and ApolloRequestBodyCreator for type conversion.

I was able to make changes using JSONResponseParser, but had to use @_spi(Unsafe) operation.__variables to the parser. I wanted to get some guidance on whether this is fragile and most likely to change in the next minor versions? I read the migration doc about spi tyles.
