Firebase-ios-sdk: In-App Messaging autolayout from background thread crash

Created on 19 Oct 2019 · 8Comments · Source: firebase/firebase-ios-sdk

[READ] Step 1: Are you in the right place?

YES

[REQUIRED] Step 2: Describe your environment

Xcode version: 11.1
Firebase SDK version: 6.10
Firebase Component: InAppMessaging
Component version: I'm using the Carthage version 6.10 not sure about component version.

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

I created and deployed my first In-App Message dialog. When I tested the campaign on my device I started to experience crash shortly after the app launches.

Nothing in the stack trace below is from my code, it's all from the Firebase SDK.

Relevant Code:

No client side code

Hey all, shooting to get a fix for this in this first release of December (the 9th).

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for the report! Looks like the responsible code is here:

https://github.com/firebase/firebase-ios-sdk/blob/16fbcf6116a13844fb8c3147d88fd8d90a5115c9/Firebase/InAppMessaging/Flows/FIRIAMDisplayExecutor.m#L315

@christibbs it's also worth noting that keyWindow was deprecated in iOS 13 and we may need to fetch the window from the connectedScenes property.

I'm experiencing the exact same crash. Here are my dependencies:

  - FirebaseInAppMessaging (0.15.5):
  - FirebaseInAppMessagingDisplay (0.15.5):
  - FirebaseMessaging (4.1.9):

I'm building with Xcode 11.0 (11A420a).
My test device is an iPhone X and runs on iOS 13.2.

Is there any progress on this issue?
Thanks.
