Upload content from app log files

We’re using sentry-cocoa, and I am looking for a way to upload log files with a crash report. Is there a recommended approach for doing this? At the moment, we have rolling log files with parameters that control the maximum size of a given file and how many we retain over time. In the ideal scenario, we would be able to upload the content of all available log files, but being able to upload the most recent one would probably cover at least 95% of what we need.
