Swift 1.2 CocoaLumberjack wrapper

Readme.md

CocoaLumberjack.swift

Prerequisites

• Add CocoaLumberjack 2.0+ in your Podfile, i.e. pod 'CocoaLumberjack/Default', '~> 2.0.0-rc'.
• Also import CocoaLumberjack/CocoaLumberjack.h in your bridging header.

Configuring the loggin

• As usual add all the loggers you might want/need: DDLog.addLogger(DDTTYLogger.sharedInstance())
• Configure the log level like so: DDLog.logLevel = .Info
• Log away :)
• You might also want to enable/disable async logging: DDLog.logAsync = false

Does this work with CocoaLumberjack beta 3 or only beta 1?

@chourobin, updated code to work with beta3.

@cfr, thanks for this! really helpful!

@cfr do you know how I should pass a formatted string to @autoclosure?

I wanted to do this, but doesn't work:

logError("oops error: %@", error.localizedDescription)

this works, but seems rather elaborate for log messaging:

logError(NSString(format:"oops error: %@", error.localizedDescription))

@cfr oops never mind, forgot I can use inline variables in swift strings, just need to rewrite a bunch of logs

logError("oops error: \(error.localizedDescription)")

Just FYI, cocoalumberjack has been updated to include Swift support and it's own cocoalumberjack.swift file.

@chourobin managed to get beta4 working with CocoaLumberjack's included CocoaLumberjack.swift file (had to include all the additional module header files in the bridging-header and comment out the cocoalumberjack import in the swift file), but unfortunately could not get the DDLogLevel filtering to work, so still using @cfr's implementation which works perfectly.

Cool stuff! Unfortunately, for some reason, I'm getting the following error on line 23 after I remove the timestamp parameter (for some reason it doesn't recognize that method signature). I'm using beta3. Any ideas?
Cannot invoke 'init' with an argument list of type '(logMsg: @autoclosure () -> String, level: @lvalue DDLogLevel, flag: DDLogFlag, context: IntegerLiteralConvertible, file: String, function: String, line: UInt, tag: NilLiteralConvertible, options: $T10)'

Works well with CocoaLumberjack 2.0.0-rc.

thanks it is really helpful!!!
I managed to display
logError("here is some error")
logDebug("here is some error") etc

However I can't see the function name, line etc information. Could someone help please? Thanks
