I would like to implement remote logging in my Swift app for iOS. Log lines will need to be sent to a server so that I can analyse problems when the app is actually being used 'in the field'. This is the easy part. For user privacy, this might be limited to TestFlight versions of the app.
The app is sometimes used in an area of poor or non-existent connectivity. So sendng the logs to our servers may fail. Therefore, I would like to see that the logs are buffered when connecting to our log server failed.
The easiest way to buffer is in Memory (Array of 'LogEntry'), but when a bug we are trying to track involves a crash ... all memory is lost, so I would like the logs to be buffered on disk.
Is there a way to do that?
Perhaps using OSLog, or perhaps some other way? I understand that on iOS, the app does not (yet) have access to its logs. That would solve my problem, cos then I can read back the logs that I made and send them to the server when needed.
I have thought about creating my own Log file, and (when there is a server connection) I read lines from the start of the file, and send that to the server. However, I have found no way to 'read and delete the first line of a file' without reading the whole file, and writing 'everything except the first line'. Seems like CoreData would not be such a bad idea, albeit a bit heavy for such a small task.
Any suggestions? Any existing components that I can include in my project? (using cocoapods, SPM?)
Thanks! Wouter
