Using swift packages in xcode

What is the proper way of using swift packages in my xcode project? I have found a swift package on github which I want to use in my local xcode project. currently I simply manually copied needed files(classes). What is the proper way of using external packages in xcode ?

swift package manager has a command to generate an Xcode project file. You can then reference that project file from another project or a workspace.

$> swift package generate-xcodeproj

So this is still the only way? bläh 8(

As long as this insane workflow continues SPM is nearly useless for most Xcode users 8(
