hey @provTheodoreNewell 👋 thanks for reporting the issue!
we made a fix and are planning to ship it as a hotfix
i'll keep you posted once this is done

The issue

we use some FileHandle methods which are only available in iOS 13.4+ and Xcode 11.3.1 has an inferior base SDK version
as a fix, we wrap this code with #if compiler(>=5.2) ... #else ... #endif; compiler(5.2) means Xcode 11.4 whose base SDK is iOS 13.4
in your case, Xcode 11.3.1, compiler shouldn't see those new methods and should compile the #else scope
