Does anyone face the same problem?

Thank you,

Which stack are you using?

[yumatan]

The workflow which contains "Flutter v0.0.8" had rarely succeeded with Xcode 11.1.x, on macOS 10.14.6(Mojave).

However, we found that it always succeeds with Xcode 11.3.x, on macOS 10.14.6(Mojave).

Is there anything that comes to mind as to what may have caused this?

Is it recommended that we always use the latest stack for building Flutter application with this step?

Thank you,

[koral--]

It is recommended to use the latest possible stack which can support your workflow. This issue is caused by OpenSSL update: https://github.com/bitrise-io/bitrise.io/pull/329#issuecomment-565508601

I'll try to continue support this stack.

[yumatan]

Thank you for your reply and information.

We will try to support the latest Xcode regarding our flutter applications.

Thank you.
