Swift: Google-signed toolchains do not work with macOS Catalina.

[rxwei]

We should fix this soon.

Agree!

We are investigating a robust way to codesign toolchains that work with macOS Catalina.

In the meantime, the Xcode 11 beta v0.4rc4 toolchain has been replaced with a locally signed toolchain. After clicking on the toolchain, you will need to do System Preferences > Security & Privacy > General > Open anyway to open it.

If someone could verify that this works, that would be appreciated!

@dan-zheng @rxwei just saw this issue and tested on my XCode 10.2.1. Unfortunately, Check and Install Now does not install July 29's 0.4 RC4 toolchain and even with Legacy Build System enabled running a simple example returns a toolchain not compatible error 🤔

hey @dan-zheng, just wanted to let you know, I tried the "10-08" dev toolchain and it causes XCode 10.2.1 to crash/quit unexpectedly. Using MacOS Mojave.

Could you please share more context?

• What triggers the Xcode crash exactly? (e.g. merely selecting the 10/08 toolchain, or using it to build, or sth else)
• How can others reproduce this crash?

Hey @dan-zheng Just saw your message. Selecting the latest toolchain keeps triggering the crash unfortunately. I'm reinstalling it, along with the 25 July and 17 June ones to see if the behavior is my Xcode specific

Ok @dan-zheng this seems connected: https://github.com/tensorflow/swift/issues/206 and https://stackoverflow.com/questions/50081481/can-not-import-tensorflow-for-swift-in-xcode-playground?rq=1
Unfortunately, still doesn't work with MacOS playgrounds and the latest August toolchain crashes XCode on my machine

The Sep 19 v0.5-rc1 toolchain works with Xcode 11 GM Seed
Well done @rxwei, @dan-zheng and S4TF team.

@rxwei you should close this issue.

[rxwei]

Thanks for verifying. Could you verify whether it works with Xcode 11 GM Seed on macOS Catalina?

On it @rxwei

Verified @rxwei @dan-zheng . Training a small conv net now on the CIFAR-10 in Xcode 11 GM seed using the Sep 19 v0.5-rc1 toolchain - on a fresh version of macOS Catalina 10.15 beta 8 (19A558d)- all beta 👍

Thank you, @8bitmp3!
