Swift Package Manager failed extracting

I’m getting this Package Manager error, when switching to a different branch or cloning the project. Build fails and “Clean Build Folder” doesn’t help.

Solution

The following steps resolve the issue forcing all packages to download.

  1. Product > Clean Build Folder
  2. Delete DerivedData content (Preferences > Locations > Derived Data little arrow)
  3. File > Packages > Reset Package Cache
  4. Build

The Reset Package Cache step is the most important here. It forces all packages to download as if they where just added.
