Solve

According to this issue https://github.com/CocoaPods/CocoaPods/issues/7327
I modified react-native-ble-plx-swift.podspec one line code
s.pod_target_xcconfig = { 'SWIFT_VERSION' => '4.1' } --> s.swift_version = "4.1"
And it works for me

Here's the code

`
require 'json'

package = JSON.parse(File.read(File.join(__dir__, 'package.json')))

Pod::Spec.new do |s|
s.name = "react-native-ble-plx-swift"
s.version = package['version']
s.summary = "React Native Bluetooth Low Energy library - Swift static library"

s.authors = { "Przemysław Lenart" => "przemek.[email protected]" }
s.homepage = "https://github.com/Polidea/react-native-ble-plx#readme"
s.license = "Apache License 2.0"
s.platform = :ios, "8.0"

s.source = { :git => "https://github.com/Polidea/react-native-ble-plx.git" }
s.source_files = "ios/*/.{swift}"
s.swift_version = "4.1"
end
`

Context

Just to bump this up. I am also having the exact issue.

I discovered this thread https://github.com/kiwi-bop/flutter_crashlytics/issues/22 and the solution of adding a new Swift file in the project fixed the issue for me

I solved this issue by making sure the pod is NOT under target '{PROJECT}-tvOSTests' do section once I moved the pods in the main pod section it was resolved. When you link by default the pods are placed under the tvOSTests section for some reaston
````
pod 'react-native-ble-plx', :path => '../node_modules/react-native-ble-plx'
pod 'react-native-ble-plx-swift', :path => '../node_modules/react-native-ble-plx'

````
