I'm not sure why it isn't possible to respect SemVer? There are several things one can do in a minor, including:
- Any rearranging of internal symbols
- Adding new classes or structs
- Adding method to structs and to existing
public(notopen) classes - Adding methods to existing protocols, as long as a default implementation is also provided
- Making classes conform to new internal protocols
- Deprecating (without removing; with
@available(… deprecated…)or similar*) existing functionality and replacing it with new methods
etc.
*: Pitches are welcome for deprecation schemes that do not involve OS versions.
