iPhones do not use the A1 chip as of quite a few years ago. Besides, the M1 and the A12+ have significant microarchitectural similarities, to the point that the DTK used the A12Z.

Furthermore, the keyboard app extension and the keyboard app are installed as a single package whose components are not supposed to communicate, hence why I brought this up.

I believe that only significant difference between A14 and M1 (apart from package) is number of cores.

The only 1 in the name of the chip is typo. The rest I'm still not sure if it is significant.
