App crashes when pressing "Start LND"
I am trying to replicate the example App.tsx in our own app and as soon as I tap the "Start LND" button the app crashes with the following message on the command line

and the following one on XCode:

Is there anything we need to add in XCode to make this work?
I believe that's an error from Lndmobile. Are you passing in any custom config options? If you leave the customFields as an empty object it'll use a working default.
I just added this to a blank project and it does start up LND:
const customFields = {};
const lndConf = new LndConf(ENetworks.testnet, customFields);
lnd.start(lndConf).then(res => {
alert(JSON.stringify(res));
});
I am actually using the example from App.tsx, which has something similar:
That's really strange. After pod install and a clean build?
A clean build didn't help either, the app just closes as soon as the "Start LND" button is pressed with the messages mentioned above. I am wondering if one needs to give some sort of permissions or capabilities to the app to access some folders...
Do we need to do anything to enable some Swift related options?
Are you running on a simulator or real device? It's possible if it's a physical device you may need to disable bitcode in xcode.

Can you replicate on Android?
If this doesn't work maybe we should make a test repo where you can replicate these sort of bugs so I can jump in and try figure out what's going on.
Just tested on Android and it works, I can start LND, yesss! This looks like an iOS specific issue indeed.
