I see it incredibly hard to type in Korean sentences precisely. Especially, I could not differentiate any words from its sound - for example, when I tried to express "I lived in Seoul", I'm going to write:
But the actual spelling is not correct, and I even don't know if it is correct or not in the first place, until and unless I look up for each word and its conjugation in a dictionary, which is a pretty intolerable action IMHO.
So I definitely want a keyboard that automatically pops up a list of prediction and spelling checker (in iOS or macOS). I'm looking for something like the one in English in iOS, but unfortunately the functionality is not available in Korean keyboard...
