Getting the following error when compiling.

Context

• Library version: 1.0.3
• Platform: iOS
• Xcode: 10.2.1
• CocoaPods

The problem is Xcode now uses Swift 5.0 by default, which requires the @autoclosure tag. The proper solution is to migrate RxBluetoothKit to 5.0 (I think it's already underway in the source repo, just hasn't been ported to this package which has a separate copy of RxBluetoothKit).

For now, it can be fixed by specifying Swift 4.2 as the compiler for this package.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'react-native-ble-plx-swift'
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.2'
      end
    end
  end
end

in my case app compiles with following code:

if target.pod_name == 'react-native-ble-plx-swift'
  target.native_target.build_configurations.each do |config|
    config.build_settings['SWIFT_VERSION'] = '4.2'
  end
end

In case anyone else ends up here, open your ios folder, open the Podfile, add the code provided by petrbela (thank you) to the bottom, then in a terminal switch to the ios folder and run the command 'pod install'

hi
where we have to use this?:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'react-native-ble-plx-swift'
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.2'
      end
    end
  end
end

Open your ios folder, find the 'Podfile' and add it to the bottom.
