Build input file cannot be found in Xcode 12.5.1

error: Build input file cannot be found: '/Users/jesphin/Library/Developer/Xcode/DerivedData/app-acbwzzdkvazcpfbaiyudpfvlkwyv/Build/Products/Debug-iphonesimulator/App News.app/App News' (in target 'App' from project 'App')

Answer 1

I had exact same error message. I was able to run the project on simulator. But when I try to Product > Archive in order to submit to App Store Connect, I was given the error message.

For my case, removing extra folder that was not needed in "Development Assets" fixed the issue. I had the main folder of the app listed there for some odd reason. Deleted that and it allowed me to archive.

App > Targets > General

Answer 2

The build cannot be found error resolved for me in mac m1 for my case.

Add arch in the Framework which shows the error in the xcode.

Build on simulator:

1. Add arm64 in Exclude arch of the Target Add arm64 arm64e i386 x86_64 in valid archs of the target

2. Add Valid_Archs as x86_64 in the framework which shown the error

   Archive Build:

3. Add x86_64 in Exclude arch of the Target.

4. Add arm64 arm64e i386 x86_64 in valid archs of the target.

5. Add Valid_Archs as arm64 x86_64 in the framework which shown the error
