Invalid `Podfile` file: syntax error, unexpected keyword_end

Which platform(s) does your issue occur on?

Please, provide the following version numbers that your issue occurs with:

• Cross-platform modules: 5.0.0
• Runtime(s): tns-ios: 5.4.2
• Plugins (the demo app created by running npm run postclone):

  "dependencies": {
    "nativescript-theme-core": "~1.0.4",
    "nativescript-twilio-chat": "file:../src",
    "tns-core-modules": "~5.4.0"
  },
  "devDependencies": {
    "nativescript-dev-typescript": "~0.10.0",
    "nativescript-dev-webpack": "~0.24.0"
  },

Please, tell us how to recreate the issue in as much detail as possible.

• sudo gem install cocoapods (if not already installed)
• mkdir plugin-test
• cd plugin-test
• git clone https://github.com/NativeScript/nativescript-plugin-seed _plugins/nativescript-version-number
• cd _plugins/nativescript-version-number/src
• npm run postclone
• I entered twilio-chat for the plugin name and chose defaults (create a demo TypeScript app)
• create the following Podfile in _plugins/nativescript-version-number/src/platforms/ios (as per Twilio Programable Chat docs)

source 'https://github.com/CocoaPods/Specs'

target 'MyTarget' do
  pod 'TwilioChatClient', '~> 2.4.2'
end

• replace MyTarget with demo
• in 2 terminal windows, both in _plugins/nativescript-version-number/src, run:
• npm run plugin.tscwatch
• npm run demo.ios

Result: [!] Invalid 'Podfile' file: syntax error, unexpected keyword_end, expecting end-of-input.
The generated Podfile (_plugins/nativescript-version-number/demo/platforms/ios/Podfile) looks like this:

use_frameworks!

target "demo" do
end

end

# Begin Podfile - /www/plugin-test/_plugins/nativescript-version-number/demo/node_modules/nativescript-twilio-chat/platforms/ios/Podfile
source 'https://github.com/CocoaPods/Specs'

target 'demo' do
  pod 'TwilioChatClient', '~> 2.4.2'
end

# End Podfile
end

Removing the end in my Podfile, I still get the same error (and just one less end in the resulting Podfile).
At one point I even got a Duplicate target "demo" error, so I even tried removing the line target 'demo' do line from my Podfile, but still no luck, still got the [!] Invalid 'Podfile' file: syntax error, unexpected keyword_end, expecting end-of-input. error.
Even if I delete all content from my Podfile, to have it empty, I still get a bad resulting Podfile:

use_frameworks!

target "demo" do
end

end

# Begin Podfile - /www/plugin-testt/_plugins/nativescript-version-number/demo/node_modules/nativescript-twilio-chat/platforms/ios/Podfile

# End Podfile
end

Comece reproduzindo o problema em _plugins/nativescript-version-number/src/platforms/ios/Podfile e compare-o com o demo/platforms/ios/Podfile gerado. Execute npm run plugin.tscwatch e npm run demo.ios e, em seguida, rastreie como o Podfile do plugin é combinado com o target de demo. Está concluído quando o Podfile gerado tiver blocos target balanceados e o comando de demo do iOS for concluído sem o erro de sintaxe.
