If I use the Swift 5.0.1. toolchain from swift.org within XCode 11, will this make binaries that can be uploaded to App Store and be compatible with frameworks compiled using XCode 10.3 with its default toolchain?
If not, why not?
Does that answer depend on whether I have the debug symbols installed?
If so, why?
Thanks

No. Generally, any additional toolchains are for experimental use and may not be accepted for App Store.

Apple made it so.
