Cantonese keyboard is not available on iOS devices!!!

I'm using iPhones and an iPad recently, but the huge problem is there are no Cantonese Keyboards available for them. I strongly recommend Apple to provide some build-in keyboards for Cantonese typing. The Cantonese keyboards should include Jyutping, 倉頡, 速成, stroke, and handwriting, available to type in traditional and simplified Cantonese, and it should be listed in the keyboard list separately. Please do not tell me to use the third-party keyboard again, because I have tried all of them, and I found no one is satisfying and the quality is not guaranteed. I strongly urge Apple to make Cantonese keyboards for Cantonese speaking users and please pay attention to us!!!
