How can I change the log level?

[haemi]

Summary: I tried to change the log level to e.g. .warning, but I always get the extensive logging.

Steps to Reproduce:

1. I imported XCGLogger
2. in the AppDelegate, immediately after launching the app, I set

let log = XCGLogger.default
log.setup(level: .error)

This seems to be the wrong approach 🙂 But how can I change the log level?
