Using NationBuilder iOS SDK with Swift

Additional Steps

1. Put use_frameworks! in your Podfile. Use pod 'NBClient', '~> 1.3.0'. Re-run Cocoapods.
2. Add bridging header to your project. See guide.
3. Refer to the same AppDelegate source to continue.

Caveats

• Xcode autocomplete for NBClient symbols may be unreliable.
