Thanks for the bug report. Can you provide any details on what triggers it or how frequent it is? We haven't seen this in testing with iOS 14 and Xcode 12 beta 6 yet, though I'm going to take a look once I get that build. How are you integrating the SDK? CocoaPods? SPM? Carthage? Other? Any detail on environment or steps to reproduce is helpful. Thanks.
Hey @jdee , thanks for the reply! I'll provide more info very soon, can't access this step for now.
I'm also having a branch crash on startup with latest branch SDK 0.35.0. I'm on iOS 13 (though 14 crashes too). Seems related to webkit (wkwebview) init thread race condition. Sorry I can't post my backtrace at this time.
edit: nevermind. seems unrelated. downgrade to 0.34.0 still crashing (likely somewhere else)
@mmdock sorry, haven't had an occasion to test it properly! Gonna try it again tomorrow.
Hi @jdee, I believe I'm seeing this crash as well. I've tested on both Branch SDK v0.35.0 and v0.36.0 running on the iOS simulator. I've been using the SDK fine for the past 6-9 months without any issue before and do not know what configuration changes I've made to cause this crash to start to occur. I've also performed the standard clean / delete derived data folder but still see the crash.
Environment: MacOS Big Sur 11.1 Xcode 12.3 (12C33) Branch SDK v0.36.0 (also occurs on 0.35.0) Cocoapods 1.10.0 iOS Simulator 13.2

Me too On simulator with iOS 13 On iOS 14 all fine
I have a Mac with M1 chip if that help
@Rusik Thanks for that bit of information. I'll try it out with an ARM mac.
Branch framework crashes on initialization startup in my case.
Dev environment:
- Xcode: Version 12.4 (12D4e)
- WebKit.framework linked as REQUIRED based on your official integration guide: https://help.branch.io/developers-hub/docs/ios-basic-integration`
- Branch iOS SDK 1.39.1: https://github.com/BranchMetrics/ios-branch-deep-linking-attribution/releases/tag/1.39.1
Crash report:
- iOS 13 simulator: CRASHED
- iOS 14 simulator: OK (no crash)
- iOS 14 real devices: OK (no crash)
@smuravev Are you able to provide the device model that's crashing? Both the dev environment and device/simulator running?
We've been unsuccessful in reproducing this issue, but suspect it may be related to certain M1 macs.
