SimpleDALPlugin load failed on other mac laptop (Mac10.14), even rebuild on mac 10.14 still load failed.

Hi, seanchas116, and all.

I rebuild this SimpleDALPlugin under os 10.15 with Xcode 12.0 and the result is good that can be found by QuickTime as an input camera.

What I really want is I can use this plugin under mac 10.14 also.
What I did ...
(1):
I want to share this plugin file to another mac laptop with os version 10.14, but after moving this file to /Library/CoreMediaIO/Plug-Ins/DAL/, it is not listed as a Quicktime input camera. (Log as below)

(2:)
I rebuild this project on that 10.14 laptop with Xcode 10.1 and still get the same load failed result.(Same Log as below)
(I change a few swift code and Xcode target from 10.15 to 10.14 to get build pass only.)

Seems like the error keeps showing: "dependent dylib '@rpath/libswiftCore.dylib' not found for..."

Any suggestion will be a big help :)
Thanks.

Log from console:

Updated for who hit this issue.

I solved it by setting "Always Embed Swift Standard Libraries = YES" in the Xcode project setting -> build option.
Solved.
