💡 Moving the SR API from DatadogObjc to DatadogSessionReplay is a breaking-change, no? What is the rationale of doing it now and what is the mitigation we will offer?

@ncreated
Truth be told, ticket originated because we missed the fact we already support obj-c in the wrapper package.

We discussed this with @maxep and it should work without a change on the customer side.

It's following the v2 idea of moving all the obj-c api directly to targets and deprecating the obj-c wrapper.

Getting this in snapshot tests:

target at '~/dd-sdk-ios/DatadogSessionReplay/Tests' contains mixed language source files; feature not supported

Will try to resolve later. But sounds like it may require slightly different approach.
