Swift Package: ld: warning: dylib was built for newer macOS version (11.0) than being linked (10.15)

I've been searching for solution to get rid of this warning error:

ld: warning: dylib (/Applications/Xcode.app/Contents/PlugIns/IDESwiftPackageCore.framework/Versions/A/Frameworks/SwiftPM.framework/SharedSupport/ManifestAPI/libPackageDescription.dylib) was built for newer macOS version (11.0) than being linked (10.15)

I tried to clean & build Xcode project but no luck

This warning error might appear to you after creating new swift package.

Solution

  • The only simple solution worked like magic is:

    1. Enter this command in your terminal:

    sudo xcode-select --switch /Applications/Xcode.app

    1. Relaunch Xcode
