I'm trying to build my Flutter app on Mac os Catalina. And would like to support old phone like Ipad 2. I read on a post the maximun version of Xcode should be 11.3.1, so i install that then install the newest version of Flutter.

But when if run

flutter build ios

i got Found "Xcode 11.3.1, Build version 11C505". Xcode 12.0.1 or greater is required to develop for iOS. So i'm trying to downgrade Flutter to the lastest version compatible with Xcode 11.3.1.

Found list of old releases but it's not easy get infos on compatibility with Xcode.

I use command line only (because VMware too slow).

At my MBP mid 2012 and iMac late 2012 with Mojave 10.14.6 and Xcode 11.3.1, I have flutter 2.0.6.

After install, if you run flutter -v doctor, you will receive a message: "! Xcode 11.3.1 out of date (12.0.1 is recommended). Download the latest version or update via the Mac App Store."

but you can run flutter code without troubles.

If I try run flutter 2.2.X, ‘flutter -v doctor’ returns a message that Xcode 12 is need.

Disclaimer for macOS 10.14.6 users:

I remember when I installed flutter, at some point I needed install gems dependencies, but I had trouble because I was using Mojave 10.14.6, Xcode and flutter.

If you have troubles with gems installation, please go to Error while installing json gem 'mkmf.rb can't find header files for ruby'

and check my answer for Mojave 10.14.6 (answered Nov 18 '20 at 14:08)
