+BluePic is a photo and image sharing sample application that allows you to take photos and share them with other BluePic users. This sample application demonstrates how to leverage, in a mobile iOS 10 application, a Kitura-based server application written in Swift.
 
 Bluepic takes advantage of Swift in a typical iOS client setting, but also on the server-side using the new Swift web framework and HTTP Server, Kitura. An interesting feature of Bluepic, is the way it handles photos on the server. When an image is posted, it's data is recorded in Cloudant and the image binary is stored in Object Storage. From there, an [OpenWhisk](http://www.ibm.com/cloud-computing/bluemix/openwhisk/) sequence is invoked causing weather data like temperature and current condition (e.g. sunny, cloudy, etc.) to be calculated based on the location an image was uploaded from. AlchemyAPI is also used in the OpenWhisk sequence to analyze the image and extract text tags based on the content of the image. A push notification is finally sent to the user, informing them their image has been processed and now includes weather and tag data.

-Optionally, if you'd like to run the BluePic Kitura-based server using Xcode, you should use Xcode 8 and configure it to use the `DEVELOPMENT-SNAPSHOT-2016-06-20-a` toolchain. For details on how to set up Xcode, see [Building your Kitura application on XCode](https://github.com/IBM-Swift/Kitura/wiki/Building-your-Kitura-application-on-XCode/d43b796976bfb533d3d209948de17716fce859b0). Please note that any other versions of Xcode are not guaranteed to work with the back-end code.

At the moment, any other versions of Xcode are not guaranteed to work. You may get unexpected behavior and/or errors if attempting to use other versions of Xcode or Swift.

 ## Getting started
 There are *two ways* you can compile and provision BluePic on Bluemix. Method 1 uses the [IBM Cloud Tools for Swift](https://ibm-cloud-tools.mybluemix.net/) application. Using IBM Cloud Tools for Swift is the easiest and quickest path to get BluePic up and running. Method 2 is manual, does not leverage this tool, and, therefore, takes longer but you get to understand exactly the steps that are happening behind the scenes. Regardless of what what path you choose, there are a few optional steps you can complete for additional functionality.
