ld: symbol(s) not found for architecture x86_64 with sh build_and_run.sh

[WillBishop]

Hey,

I'm trying to set up the 'Creating an Xcode Project' section in MediaPipe iOS Setup.

I have bazel 0.28.1, and I symlinked my mobile provision to the directed directory.

Upon running sh build_and_run.sh, I got the error FAILED: Build did NOT complete successfully, with further details

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Target //:tulsi failed to build
Use --verbose_failures to see the command lines of failed build steps.
INFO: Elapsed time: 54.326s, Critical Path: 32.17s
INFO: 38 processes: 25 darwin-sandbox, 13 local.
FAILED: Build did NOT complete successfully

I tried it again with --verbose_failures and got this:

Error was too big for Github, I hosted it on my own server

This is actually an issue with https://github.com/bazelbuild/tulsi.

@WillBishop We have gotten examples of users successfully building MediaPipe for iOS. https://twitter.com/2020cv_inc/status/1163971960285478912?s=21

I guess you're using xcode 11 beta 4 or higher.
Apple moved swift libraries into "swift-5.0" directory, hence tulsi fails to build.
A workaround would be soft-linking the libraries from "swift-5.0" to the "swift" directory and then re-run the build process.
