Why isn't there a Pinyin tone in the Apple input method?

Answer 1

Apple's input method is often called Apple Touch ID or Apple Script, and it uses Swift programming language and javelin scripts. Although Apple Script supports Pinyin input and tone input, it doesn't have a built-in tone function. This may be due to Apple's higher priority for Pinyin input or due to technical limitations.

Apple's input method was usually used for English input, and there was no tone system in English, so Apple Script could not use tone input. In addition, Apple's input method usually required the user to manually input Pinyin and tones, so it was difficult for the machine to automatically recognize tones.
