Did you test this in scale factors other than 1X?

Normally we avoid autoreleased objects. I would have expected alloc/init and RetainPtr here instead. Probably fine either way, though.

Seems to me we should have a helper function to turn a HashMap<String, String> into a NSDictionary *, rather than doing it in the middle of this function.

I find this function slightly confusing. Too much of it is connective tissue converting things to Range and then Range’s API is so awkward. If the whole body of the function once the ranges were created was a named helper function then I could probably understand it perfectly. It’s not clear what compareBoundaryPoints and isPointInRange are accomplishing and the function name would probably clear that up.

I don’t think the wordStart and wordEnd locals are needed or helpful.

Would be nice to only define this once instead of defining it in both sides of the #if.

The isNone check is redundant and could be omitted.

Would be nice to only define this once instead of on both sides of the #if.

Would be nice to have a function to convert a NSDictionary of strings into a HashMap<String, String> instead of doing it inline in a loop. Although that is a pretty tight loop!
