[Hayden Seay]

Here is the output on an iPhone 11 Pro.

diatrus@Grey-7 /p/v/diatrus [125]> bash test.sh
uname -m = "iPhone12,3"
uname -p = "arm64"
uname -r = "20.2.0"
uname -s = "Darwin"
uname -v = "Darwin Kernel Version 20.2.0: Fri Nov 13 01:00:15 PST 2020; 
root:xnu-7195.62.1~4/RELEASE_ARM64_T8030"
