Hi there,

We have been using the cathrage.sh since Xcode 12 and it seems working great, but suddenly the tvOS failed starting in this month, but we changed nothing about the process.

And furthermore, iOS and CI passed at the same time, with same code and setup. It's really confusing for us how to fix it.

The error for tvOS build:

the script we use: https://github.com/danielgindi/Charts/blob/master/.travis.yml

We have a script to run copy frameworks:https://github.com/danielgindi/Charts/blob/master/scripts/copy-carthage-frameworks.sh

Could anyone shed some lights?

it seems this error comes from carthage cannot run the command correctly for tvOS, but iOS is totally fine. Don't know why.

I wonder who is creating

A shell task (/usr/bin/xcrun lipo /Users/xl/Development/GitHub/ios-charts/Carthage/Build/tvOS/FBSnapshotTestCase.framework//FBSnapshotTestCase -output /var/folders/8v/6dg7d6mx2850sv1gp8ts9thm0000gn/T/carthage-lipo-VZRwrb/FBSnapshotTestCase)

Seeing the exact same thing, though it did not start until we moved to 0.37.0.

[danielrbrowne]

I've seen this issue too - I flagged this on the (seemingly) related issue: #3112 (comment)

[liuxuan30]

@danielrbrowne any idea why iOS is fine, tvOS suffers?

[elliottwilliams]

I think this should be fixed as of #3155 and v0.38.0. Feel free to reopen if you're still having issues.
