SOLVED: authorizeAsync(authCode) crashes iPad, but not simulator.

[cezarcarvalhaes]

When I run the authorizeAsync method on an iPad, the app crashes and cannot restart. The code runs, as I am able to log the value after the await, however the app crashes (stops and force exits) right after. To run again, it needs to be reinstalled (deleted and rebuilt in xcode). The app only crashes with a valid authcode. Invalid codes return proper error messages and the app continues running fine.

It works as expected in the simulator however.

Device permissions are working fine and handled in previous screens.

To Reproduce

For example -

1. Connect iPad device to Xcode and build app to that device
2. Call authorizeAsync(authCode)

Here the piece of code that reproduce the issue.

 import { authorizeAsync } from 'react-native-square-reader-sdk';

  authorizeReader = async (authCode) => {
      try {
          // using a generated mobile auth code for quick start
          const authorizedLocation = await authorizeAsync(authCode);
          console.log(authorizedLocation);
      } catch(error) {
          console.log(error)
      }
  }

Expected behavior

Authorization method resolves and the app continues running.

UPDATE:

I added an exception breakpoint, and then called bt after the (lldb) in the console and this is what I got:

Frame 3 says __CRASHING_DUE_TO_PRIVACY_VIOLATION__, however I followed the instructions for updating info.plist. Here's a snippet of what I added for square in case I missed something:

After a ton of headbanging, I found the issue. With iOS 13 Apple also requires NSBluetoothAlwaysUsageDescription in addition to NSBluetoothPeripheralUsageDescription. I updated that value and it's working fine now. https://developer.apple.com/documentation/bundleresources/information_property_list/nsbluetoothalwaysusagedescription

I'll submit a pull request to update the getting-started doc.
