React-native-ble-plx: Linker Error finding Swift Support Libraries

[paddlefish]

Prerequisites

Start with a react-native app (not ejected Expo)

Expected Behavior

Build and run

Current Behavior

Linker error:
ld: warning: Could not find auto-linked library 'swiftFoundation'
ld: warning: Could not find auto-linked library 'swiftDarwin'
ld: warning: Could not find auto-linked library 'swiftCoreFoundation'
ld: warning: Could not find auto-linked library 'swiftCore'
ld: warning: Could not find auto-linked library 'swiftCoreGraphics'
ld: warning: Could not find auto-linked library 'swiftObjectiveC'
ld: warning: Could not find auto-linked library 'swiftDispatch'
ld: warning: Could not find auto-linked library 'swiftSwiftOnoneSupport'
Undefined symbols for architecture arm64:

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Install react-native-ble-plx using yarn add
2. react-native link
3. Build-and-Run in Xcode

Context

The fix is to add a single empty swift file to your main app. This will trigger Xcode to link in Swift and create a bridging header.

We should update the README to include this simple step

[paddlefish]

Oh my, I'm sorry, the README already says that and I skimmed over it. So sorry!

(feels embarrased)

@paddlefish The fix you suggested worked when I experience the issue integrating opentok-react-native
