Comment:

 The guide says:

 > '''universal_archs''' \\
 > The machine architectures to use for +universal variant (multiple
 entries must be space delimited). Options include: arm64, i386, ppc,
 ppc64, x86_64 \\
 > Default: arm64 x86_64 for macOS 11 and later, x86_64 i386 for 10.6
 through 10.13, ppc i386 for 10.5 and earlier

 That's accurate. On 10.14 and 10.15, universal builds are not possible.
 You can only build non-universally, for x86_64.
