XCode 10 beta 6: Crash on quick reply from push notification

[saitun]

Mixpanel pod version: 2.4.5
XCode: 10.0 Beta 6

This happens consistently when doing a quick reply through push notification. Below is the error message and a screenshot of the crash in XCode.

Thread 1: closure argument passed as @noescape to Objective-C has escaped: file /.../Pods/Mixpanel-swift/Mixpanel/AutomaticEvents.swift, line 289, column 77

This is the stack trace which doesn't look very useful:

hi @saitun, thanks for raising this! We will address all XCode 10 related issues as a high priority.

[zihejia]

We have released 2.5.0 which supports Xcode 10. The issue could not be reproduced, however if the problem still exists, please reopen it.

[saitun]

@zihejia Thanks for the update. I am however having problem installing the latest 2.5.0 version.

[saitun]

Anyway I updated the pod by pointing to the latest commit and it works and I don't see the crash anymore. Thanks again.

hi @saitun , sorry about that, it's caused by the wrong tag in our end. I have fixed it now.
