I find ++ easier to parse than += 1, because my head-parser can
avoid looking at a number and remembering that number to
interpret control-flow/intention :o)
I also must admit that I don't see the benefit of removing for
loops. There are legitimate use-cases where you really want that
numerical index, be it because you iterate two arrays of the same
length simultaneously, or be it because you have to enumerate the
indices anyways so might as well use them for getting an index:
for(int i = 0; i < 5; ++i)
arr1[i] += arr2[i];
And
for(int i = 0; i < 5; ++i)
arr[i].SetIndex(i);
My guess, not knowing Swift, is that you will now implement these
in a more verbose, harder to read way using while or use some
concept similar to C#s LINQ or Ds ranges to somehow automatically
apply this type of functionality.
Both seem way more awkward than a normal for-loop.
Whereas I must admit I could not enumerate any benefit outside
"slightly, very slightly less complex language" and "it *might*
stop people from doing really complex things with the index
inside the loop body, causing bugs", which imho do not outweigh
the breakage + probably lost convenience in certain cases.
