The app gets crashed because of xcglogger swift

Question

I am using the XCGLogger with correct compatibility (My Swift language is 3.2 and XCGLogger version is 5.0.5)

But still the app crashes with the following crash report

Here is the code where the crash occurs:

public func onResumeUserSession() throws {
    AppDelegate.getAppDelegate().log.debug("onResumeUserSession()")
    try validateUserSessionBeforeResuming()
}

Please help.

You haven't provided enough information or code to really dig into the issue.

However, you're using a version of XCGLogger that's over a year old, as well as an old version of Swift. Are you still using an old Xcode version as well?

I would recommend updating to Xcode 10 (the most current version at the time I'm writing this), update all libraries (including XCGLogger) to the most recent versions, and update your project to Swift 4.2.

There have been lots of fixes over the last year and I'm sure you'll find this crash goes away once you've updated.
