I like your use of the term "lossless"; perhaps we can use it consistently, i.e. LosslessStringConvertible.

1. ValuePreservingStringConvertible expects its description to be value preserving, but current Cocoa implementations are not.<br class="">
2. ‘Description’ doesn’t really convey the meaning of ‘value preserving’ in my mind, but is a valuable name for many other use cases.<br class="">

4. With the presence of ValuePreservingStringConvertible, CustomStringConvertible doesn’t seem to provide much value over CustomDebugStringConvertible?<br class="">

For string interpolation, I imagine the standard library could fall back to a ‘description’ method for NSObject subclasses.<br class="">
