Description

Build for iOS fails with

with clang: error: no such file or directory: '/Users/user/Library/Developer/Xcode/DerivedData/app-eziwvgytfcyckcazzowfryoaspuu/Build/Products/Debug-appletvsimulator/libRCTAnimation.a'

libRCTAntimation seems to be linked correctly to me. I am unsure on why appletvsimulator should be an issue. This is targeted as a iPhone project.

I had the same issue with the ‘Debug-appletvsimulator’ DerivedData path being used - I tracked the issue down to linking the wrong target version of the library I was using. If you run into this, make sure to select “libxxx.a from ‘xxx’…” and not “libxxx.a from ‘xxx_tvOS’…” when adding the link under Build Phase (where xxx is the library).

This solved it for me: switching to the legacy build system
