Update iOS Sample to compile on Xcode 9.4

jameshartt commented 6 years ago

Been interested in using Lambda functions for a simple use case at https://www.shootmavis.com. My current expertise is iOS, so wanted to use the examples here to start creating my first few functions. But noticed the example for iOS was quite a bit out of date.

This PR contains various changes as described in detail, in the separate commits.

In summary, the changes are as follows:

Update the cocoapod file to allow pod install, including allowing frameworks and pinning the iOS version.
Update to Swift 4.1
Apply XCode recommended project file updates
Fix storyboard button actions to point to updated function names generated by Swift.

The project now compiles, and will work if the steps in the README steps are followed.

@jameshartt do you plan to update the project to Xcode 10 and Swift 4.2?
