Also have reports of a crash on iOS 13.1, SDK 34, iPhone 11 Pro Max. Here’s the crashlog from xcode:

Hello, for expokit with SDK34,
What do i need to do to resolve this issue?
I just need to update the expo-cli and rebuild the binary in Xcode 11?
or I should also upgrade expo, expokit , RN minor version in npm?

I want to know that too (in the same situation, expokit with SDK34)

@esamelson
please tell us what to do.

Hi there-- for expokit, you’ll need to update the ExpoKit tag in your Podfile to ios/2.12.5, rerun pod install and then rebuild your binary in Xcode. (For SDK 33, use tag ios/2.11.5).

@esamelson
Thank you for your advice but your solution didn’t well.

The quote of my package.json is like this

“react-native”: “https://github.com/expo/react-native/archive/sdk-34.0.1.tar.gz”,

And I think this source doesn’t include your commit to solve this crash issue.

I want you to show me your idea about this.
also I want to know additional solution if you have any information.

Hi there - you don’t need to have the Objective C fixes in your node_modules, only in your Pods folder. If you follow the instructions I posted above, that should be enough. Have you tried following those instructions and are still encountering the same crash?

Thank you for your comment!

Sure. I have tried your instructions twice and my colleague has too.
I wonder if my Podfile is a bit different from yours because I have upgraded my app from expokit30 to expokit34

My Podfile is like this.

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'

target 'xxxxxxxxxxxx' do
  pod 'Firebase/Core'
  pod 'ExpoKit',
    :git => "http://github.com/expo/expo.git",
    :tag => "ios/2.12.5",
    :subspecs => [
      "Core"
    ],
    :inhibit_warnings => true

  pod 'React',
    :path => "../node_modules/react-native",
    :inhibit_warnings => true,
    :subspecs => [
      "Core",
      "ART",
      "RCTActionSheet",
      "RCTAnimation",
      "RCTCameraRoll",
      "RCTGeolocation",
      "RCTImage",
      "RCTNetwork",
      "RCTText",
      "RCTVibration",
      "RCTWebSocket",
      "DevSupport",
      "CxxBridge"
    ]
  pod 'yoga',

After I put your commited files(RCTActionSheetManager.m, RCTReconnectingWebSocket.m) into my node_module/react-native directory, my app’s crash was fixed.

Thanks!!

Ah, sorry for the confusion. I’ve gone ahead and tagged versions sdk-34.0.2 and sdk-33.0.1 of expo’s react-native fork, which have the bugfix. You can go ahead and install those if you’re using expokit. (Note that you also still need to follow the podfile instructions I posted above in order to get all the fixes!)

Any news about it? My app facing this problem too, upgraded to 35 but users still report crashed on IOS 13 :frowning:

35

I upgraded to SDK 35 and using managed version. But still crashes on ios 13

36

@ngocthua92 do you have a stacktrace for the crash?

37

So sorry, I dont have stacktrace. It’s users report to me, about 10 users reported, but my device is not crashed :frowning:

Updated: I know how to get crash log, and here my log:

@ngocthua92 this looks to be WebView related, I’d do a pass over any code in your app that’s using a WebView to try and reproduce the issue. I don’t think this is related to the iOS 13 crash that’s the original subject of this thread.

Yes, I know it’s other error code. Thanks for your support and looking forward to a solution from you!

To clarify, looking over your WebView usage is what I would suggest you do to try to pinpoint the cause of the crash. If you find a reproducible way to cause this crash, feel free to open an issue on GitHub and we’ll investigate further at that point. Sorry for the confusion!

Dont mind. But it’s so weird, my app do not use any webview, so the first thing I thinking is about ads-mod, I show a fullscreen Interstitial ads when user open app. I will remove it and try to publish new version. I will give you feedback when I have result. Thanks for you support. Love Expo Team :smiley:

Hi guys do you have any updates on this? We upgraded to SDK 35 yesterday and are still experiencing crashes on iOS 13. Is there a workaround?

43

Unfortunately, not yet. I’m still looking someone can resolve it for me :(. Please helppppp!

44

Did you found the solution? Can you share me? My app still crashes :frowning:
