      Description

      protocol SettingsFile {}
      protocol SpecificSettingsProvider {}     // NOTE: This doesn't inherit SettingsFile, on purpose. We use a composition instead.
      
      protocol SettingsFileInfo {
      	associatedtype FileType : SettingsFile
      }
      
      struct SpecificSettingsFileInfo : SettingsFileInfo {
      	typealias FileType = protocol<SettingsFile, SpecificSettingsProvider>
      }
      

      Gives an error that SpecificSettingsFileInfo doesn't conform to SettingsFileInfo because FileType doesn't conform to SettingsFile.
