iosswift5xcode10.2

This copy of libswiftCore.dylib requires an OS version prior to 12.2.0

The app crashes on launch when running from XCode 10.2 (before and after Swift 5.0 migration) with this on console

This copy of libswiftCore.dylib requires an OS version prior to 12.2.0.

I understand the error, but not sure what is required to fix this.

Solution

  • Make sure /usr/lib/swift is the first argument for runtime search paths for linker if iOS >= 12.2, it should load platform libraries.
