I am not a mac user and started using VS 2019 mac 2 months a go. I have done all my Android releases using VS windows till today.
Release build+archiving takes more than 30mins every time using aot+llvm+bundle into native assemblies+full linking+ split into separate apks+proguard+dex
Yesterday i tried using VS 2019 mac latest Pre version.
Release build was like 2 mins
Installing on my samsung s10+ 5 mins
Archiving apks 10 mins (even maybe less)
Biggest surprise for me was my app size using windows 39mb, mac produced 25mb
App is running fine on my phone without any crash.
I havent tried latest VS2019 windows version yet. maybe same there now. I will try it also as soon as possible to compare.
if you did such big improvement congratulations
PS; my Windows machine is probably 2 times more powerful than my Macbook.
