appium 1.18.1 and Xcode 12 beta 6 - Building scheme "iOS Framework" in CocoaAsyncSocket.xcodeproj failure

The problem

I’m trying to run my first test on Xcode 12 - Beta 6 but I get a Carthage failure when running ./Scripts/bootstrap.sh

Environment

• appium version: 1.18.1 and v1.18.0-beta.1 (same results with both versions)
• Node.js version (unless using Appium.app|exe): v12.18.3
• Mobile platform/version under test: iOS 14.0 Simulator (Xcode 12, Beta 6 - 12A8189n)
• macOS version: Catalina 10.15.6 (19G2021)
• Carthage version: 0.35.0

Details

• When I first ran ./Scripts/bootstrap.sh I got the this error:

• Then I tried the solution mentioned here (which implies replacing bootstrap.sh) https://github.com/appium/appium/issues/14611#issuecomment-684877737 and then I got this error:

Please advice.

Thank you in advance!

Please try out appium@beta for Xcode 12 beta.

We’re not sure what Xcode will be in its release (they are adding changes in its beta releases), and the current workaround will be. so the release will be after Xcode release at least, I guess.
