I have an iPad Pro with the Apple Smart Keyboard, which works well. I usually use it with the Colemak hardware keyboard layout, which comes built in to iOS.
I know that it is possible to install apps which give you custom virtual keyboards. Is it possible to do a similar thing but for hardware keyboard layouts?
In my case, I have a custom layout that I use on my computer to type the special characters in the International Phonetic Alphabet, and it would be nice to be able to use it on my iPad too.
(Please note that I am not asking how to install third-party virtual keyboards; I specifially want to install a hardware keyboard layout.)
