I've been seeing a few of these crashes:

@gilroykilroy Can you please give me some more info. How you're reproducing this. What version of Xcode etc you're using.

It just happened a few times. Nothing I could reproduce nor figure out why. I always use the latest Xcode available. Alas due to this issue sitting there for a while I switched to SwiftyBeaver and added my own rotate log code to it.

Hi i use the XCGLogger Version 6.1.0 github "DaveWoodCom/XCGLogger" "6.1.0" and get sometimes the File Rotataion Crash at syncronizeFile()
may be you will add a Lock on the File Handler to fix it?

private func closeFile() { logFileHandle?.synchronizeFile() logFileHandle?.closeFile() logFileHandle = nil }

Here is the Crash Report
