[swift-corelibs-dev] incomplete implementation warning functions

[Will Stanton]

Hello Tony,

Thanks for your reply and sorry for my late one – I thought I could fix the whole file but then saw how long it was, and snow came. Oops!

I think the approach to future merges is very reasonable.
Still, I am skeptical log messages would be unbearable, especially once/run for debug.

Finally, some implementations seem hard to write without knowing how Apple Foundation does it, but I’ll save that for another day!

Regards,
Will Stanton

I think in this case we should prioritize fixing the TODO and in future merges we should make sure it’s functional enough to work when merged, or crashes if you’re doing something that we haven’t yet implemented yet.
