ok, does it mean that if you implement only parts of the patent (say only a single feature) there's no infringement because then it doesn't "fit the language of the claims"?
Also, "using Swift" isn't in the claims ¯\_(ツ)_/¯

When drafting the claims writer (patent attorney or agent usually) will add clauses to work around prior art. You can't just add unrelated features though, the features need to have synergy to represent a single invention.

This is not legal advice.]
