The author later speculates on why: > I actually was thinking along the lines of "interesting coincidence" but now I actually believe it is not a coincidence and they really did do this just to prevent people discussing welding Bing and "AI" into the FUCKING KEYBOARD
Thus iOS support is just at:
https://support.swiftkey.com/hc/en-us/categories/200371942-i...

https://support.microsoft.com/en-au/swiftkey
IMO this falls into "don't attribute to malice that which is adequately explained by stupidity"
