logmatic-ios's Issues

Carthage support

Is it possible to support Carthage ?
Thanks

I recently integrated the Logmatic pod into our swift 3 app and I am getting about 4 compiler warnings. The project still runs and logs without problem, but these warnings are rather messy. Do you guys mind taking a look into this?

EXC_BAD_ACCESS KERN_INVALID_ADDRESS (LMLogger.m lines 209 and 230)

We're using Logmatic through CocoaPods, version 1.0.2, in our Swift 3.1 app. Crashlytics by Fabric has reported several crashes traced to Logmatic. Two stack traces are pasted below:

Crash Insights

Heads Up!
Heap corruption

The stack trace indicates that heap corruption may have caused your app to crash. Memory corruption can occur pretty easily from freeing a dangling pointer, a thread race, or bad pointer arithmetic. The important thing to keep in mind is that the resulting crash may happen long after the initial corruption. As a result, the stack trace for this crash might not provide any clues to the location of the bug in your code. However, you can still fix memory issues with tools from Apple. For speedy resolution of memory corruption issues, we recommend regularly auditing your app with Xcode’s memory debugging facilities: Visual Memory Debugger, Zombies Instrument, Address Sanitizer, Thread Sanitizer and malloc diagnostics.

[LMUserDefaultsPersistence replaceLogs:] is called with pendingLogs (from LMLogger) passed as parameter. My guess is that pendingLogs is modified somewhere else at the same time it is used to be archived.

Logmatic iOS version: 1.0.2.
