Xcode 12 Problems: “Build input file cannot be found ”- Building for release on a react native app

Question

When I try to do an archive build for "any iOS device", I receive this error:

Build input file cannot be found: \'/Users/.../Library/Developer/

Answer 1

Build for "Any iOS Device" (for example, "Archive" because you want to upload to AppStore):

• Delete arm64 from "Excluded Architectures"
• Delete x86_64 from VALID_ARCHS
• Add arm64 to VALID_ARCHS

All this changes on both "Build Settings", project and target. And if you want to build for simulator do the inverse path:

• Add arm64 to "Excluded Architectures"
• Delete arm64 from VALID_ARCHS
• Add x86_64 to VALID_ARCHS

That works for me.
