Adds iOS target

[esttorhe]

Fix #24

I just created a new target with its own test target and "redirected" the same tests to run for the mobile architecture.

A couple of conditional target imports in 3 files and the project now supports iOS framework with tests passing :)

@esttorhe I've checked your PR and it looks fine but I suggest you change both target names to follow some pattern eg.

• XcodeServerSDK - OS X
• XcodeServerSDK - OS X Tests
• XcodeServerSDK - iOS
• XcodeServerSDK - iOS Tests

Also I've noticed that Tests for new iOS target are marked as red in Product directory. You know something about this and where to fix this?

When you fix these things I think this PR will be ready to merge from my POV.

I've also checked - your PR will allow us to use Playground inside project so we can interact with SDK. Everything in that matter is configured as it should be and is described in #26.

Good job! 😉 👌

Here's the list of fixes:

• 1. Renamed targets as suggested on your comment
• 2. Removed Info.plist for iOS target as its not needed (using same as the OSX target)
• 3. Renamed product names

Regarding your question of the test target in red; basically Xcode is a «String based» IDE, now that both targets share the same product names Xcode will search for the same (in this case OSX one) and that's why you see both iOS and OSX targets in black (because both products are pointing to the same artifact) but the test target had different names and Xcode was looking for the iOS test product in the same folder as the OSX ones failing to find it. ¯_(ツ)_/¯

Awesome, thanks @esttorhe and @cojoj. I have some slight edits for this but I'll merge this first and push those changes to the original repo's swift-2 branch right after.
