error: Filename "R.generated.swift" used twice: in SPM library

[harshvishu]

I am using R.swift in an internal library and while migrating from version 5.1.1 of R.swift from cocoapods (Podspec) to swift packge I am encountering the following error.

error: Filename "R.generated.swift" used twice: 
'/Users/xxx/Starship/DesignSystem/Sources/DesignSystem/R.generated.swift' and
'/Users/xxx/Library/Developer/Xcode/DerivedData/DesignSystem-
-------/SourcePackages/plugins/designsystem.output/DesignSystem
/RswiftGeneratePublicResources/DesignSystem/R.generated.swift' 
(in target 'DesignSystem' from project 'DesignSystem') 
note: Filenames are used to distinguish private declarations with the 
same name (in target 'DesignSystem' from project 'DesignSystem')
