From the iOS section of the GMS2 Required SDKs Article:GMS2 doesn't require XCode 11, does it? Cause I just have High Sierra and can't upgrade to Catalina because of all my old 32 bit apps.
For simply playing GMS2 games: iOS 10.0 or above, tvOS 12.0 or above, iPadOS 13.0 or above. All games are 64bit-only.
- Requires Xcode 11 to build all projects, which requires macOS Mojave 10.14.4 or newer
- Please note that whilst Xcode 11 will still build projects targeting iOS 9 or older, Apple doesn't support anything older than iOS 10, these devices often can't access the AppStore so there's no real commercial need to do work to support them, and in order to submit to the AppStore you need to support all the newer iOS versions... So please don't test using only old devices!
Please also note that most of these requirements, and their frequent changes, are caused by third parties changing their requirements - so YoYo Games has to follow suit.This article is targeted at users with the macOS version High Sierra 10.13.4+. However, if you are using an older version of macOS then you may still be able to test and compile your games whilst Xcode remains supported on your OS, but some steps may be slightly different and you will only be able to test on iOS versions that are compatible with the version of XCode that works with the macOS being used. We recommend that you have the latest macOS and the latest Xcode to build games for iOS.
