React-native-ble-plx: [iOS]: Crashed: com.facebook.react.BleClientManagerQueue EXC_BAD_ACCESS

[mazenchami]

Expected Behavior

When I initialize new BleManager(), the app shouldn't crash.

Current Behavior

On opening of page that initializes BleManager, the app crashes

Context

• Library version: 1.1.0
• Platform: iOS
• React-Native Version: 0.59.4
• Xcode: 11.2

The error in the title is what I get from Crashlytics for either AdHoc or Release builds. Works as expected in debug.

I have put the code below in constructor, componentDidMount, & componentWillMount and still have the same error

let bleManager = new BleManager();
bleManager.onStateChange(state => this.setState({ bleState: state, }), true);

Getting something similar as well. Haven't found a fix yet.

[mazenchami]

@Balake can you please post your react-native info?

[BinhTNT]

I get the same issue. Hope it would be fixed. Thanks

[Balake]

I was able to fix this by downgrading to Xcode 11.1.

[BinhTNT]

@Balake I tried with Xcode 11.1, the crash didn't happen any more. Anyway, this is best solution currently. Thanks

[ital0]

My five cents of contribution: even if you update to Xcode 11.2.1 GM Seed, the error still occurs.

[gre]

Same issue, it crashes at boot of our app (in production build).

I tried this way on Xcode 11.2.1 and works: https://stackoverflow.com/questions/58595718/swift-initclassmetadataimpl-exc-bad-access-with-xcode-11-2-1

[gre]

it seems that upgrading to React Native 0.61 (from 0.59) did the trick for us.
