iOS calculator sample

This example shows how to use Kotlin library compiled to framework from an existing iOS project (e.g. written in Swift or Objective-C).

To build and run the sample do the following:

1. Open samples/calculator/calculator.xcodeproj with Xcode.

2. Open the project's target through project navigator, go to tab 'General'. In 'Identity' section change the bundle ID to the unique string in reverse-DNS format. Then select the team in 'Signing' section.

   See the Xcode documentation for more info.

3. Now build and run the application on a connected iPhone with Xcode.

The sample consists of:

1. Xcode iOS application project, written in Swift. It uses Kotlin library to parse simple arithmetic expressions.

2. Kotlin library source code and build script. It is built into Objective-C framework by invoking Gradle from custom "Run Script" build phase, and this framework is imported into the Xcode project.

   The library can also be compiled to a .jar by Kotlin/JVM compiler with Gradle.
