If the demo apps cannot help and there is no issue for your problem, tell us about it

On a brand new app, with nothing but the core modules and input mask, I can't build the app for iOS since when the CLI tries to check the Pod for the input mask plugin it fails with the following error.

`[!] Unable to determine Swift version for the following pods:

• InputMask' does not specify a Swift version and none of the targets (InputMaskTest) integrating it have the SWIFT_VERSIONattribute set. Please contact the author or set theSWIFT_VERSION attribute in at least one of the targets that integrate this pod.

The podfile looks like this (I saw the other issue about the non-existent location and have the file on the mentioned folder):

target "InputMaskTest" do
`# Begin Podfile - /Users/hb/Projects/ProjetosTestes/InputMaskTest/node_modules/nativescript-input-mask/platforms/ios/Podfile
pod 'InputMask', :path => '~/Projects/input-mask-ios'

def post_installnativescript_input_mask_0 (installer)
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.0'
    end
  end
end
`# End Podfile

post_install do |installer|
  post_installnativescript_input_mask_0 installer
end
end
