Description

I have released my app for testing by a specific group of people via Apple's TestFlight.
For most of the testers it seems to work perfect, but I had 1 person reporting a crash, I loaded into XCode and got the RCTFatal + 448 error.

Which seems to relate to:

Found in:

At this moment no idea what it is causing the crash. So no idea what code to provide.

@udarts Did you solve it?

@radik nope, as I still have no idea what the issue is and why it happened.

@udarts Do you have this problem on Android?

@udarts For me, it has exactly the same behavior on android (signed release apk): shortly crashes after start.
Also, it crashes in release mode on iOS:

react-native run-ios --configuration Release

[radik]

@udarts I'm not sure, that this will help you, but I found a reason for my project.
Having "@babel/plugin-proposal-decorators" as plugin for babel cause crash of app in release mode.
After removing all @observer and @observable from mobx package my app is finally started in release mode. Here is the diff of .babelrc:

--- a/.babelrc
+++ b/.babelrc
@@ -1,13 +1,5 @@
 {
   "presets": [
     "react-native"
-  ],
-  "plugins": [
-    [
-      "@babel/plugin-proposal-decorators",
-      {
-        "legacy": true
-      }
-    ]
   ]
 }

This is not a proper solution, but at least I found a reason. Still working to figure out what to do.

@udarts Please, let me know if you find anything related to issue.

I haven't tested because I have some many decorators, but I also get this error and use the legacy transform decorator plugin. This started happening after I upgraded react native to 0.57 which is using babel 7.

[tcodes0]

I think I'm on the same boat. It's hard to replicate it, but i'll take a look at the .babelrc and try to remove any decorators. And upgrade RN

[nicholasc]

Upgrading react-native from 0.57.1 to 0.57.3 fixed this for me.

[lenvonsam]

I have faced same problem, any solution?
react-native 0.55.0
react 16.3.1
@udarts

[aramvr]

Is anyone solved this problem?

@nicholasc can you confirm this today? Did you checked Xcode crash logs at these days?
