@Vincent_Galilieo is right that way it works just make sure your external package doesn't take too much space as the size limit for your zip file is max 25 mb. So @advaitconty just download your packages locally and then create an folder besides your playground and save it there and then while adding packages in Xcode make sure to add that package with the same relative path. ( which is default if you are not editing package.swift file yourself ).
