xcodegen 2.19.0 fails to run on Mojave due to missing CryptoKit framework

Hi 👋, I'm currently working on packaging version 2.19.0 for Homebrew (progress at Homebrew/homebrew-core#71781). We're currently running into an issue where the built binary doesn't seem to want to run on macOS 10.14 (Mojave):

==> /usr/local/Cellar/xcodegen/2.19.0/bin/XcodeGen --spec /private/tmp/xcodegen-test-20210223-82884-wnda1w/xcodegen.yml
dyld: Library not loaded: /System/Library/Frameworks/CryptoKit.framework/Versions/A/CryptoKit
  Referenced from: /usr/local/Cellar/xcodegen/2.19.0/bin/XcodeGen
  Reason: image not found

We believe the dependency is being pulled from Xcodeproj here, where it looks like CryptoKit should be linked if available (but workarounds are present if it's not available). However, I'm bringing this issue here just to see if we're wrong in analysis and figure out the correct steps to resolution.

Let me know if there's anything else you need from us that can help make troubleshooting or fixing this easier. Thanks!

Have opened a new PR to Homebrew for 2.20.0 which simply requires Catalina Homebrew/homebrew-core#74854
