Q: Use in a concurrent environment

[richardtop]

Hi, I'm curious whether it's allowed to use SwiftyBeaver in a concurrent environment. Let's consider we have 2 targets: an iOS app and an app extension, both are sharing the storage via the Shared Container.

Is there any limitation on whether we can log from both targets simultaneously? Should we implement the locking?

Each destination has its own queue and SwiftyBeaver can be used in parallel environments.

So they can write to the same file? No conflicts etc? Thanks.

What file do you mean?

[richardtop]

i.e. using this: https://github.com/SwiftyBeaver/SwiftyBeaver/blob/master/Sources/FileDestination.swift
with a file url that is shared between an app target an an app extension, so that the logFileURL is pointing into a common container, https://developer.apple.com/documentation/foundation/nsfilemanager/1412643-containerurlforsecurityapplicati

ah you are using the FileDestination. It was actually initially just meant to be used for local macOS development. So you are right, it may lead to conflicts.

[richardtop]

Ok, then could you reopen this, as there is a way to implement it with the help of concurrent file operations (this is supported by the OS).

good idea, reopening and asking for contributions to extend the usability of the FileDestination to more than 1 consumer.
