Start updating iOS docs.

This removes the docs for the old GYP-based local development and
replaces them with ones for GN-based development.

I have not yet updated the docs for iOS on the bots... still in flux.

 Mac users may want to pass `--ide=xcode` to `bin/gn gen` to generate an Xcode project.
 
+iOS

+
+Googlers who want to sign and run iOS test binaries can do so by running something like
+
+    python gn/package_ios.py out/Debug/dm
+    python gn/package_ios.py out/Release/nanobench
+
+These commands will create and sign `dm.app` or `nanobench.app` packages you
+can push to iOS devices registered for Google development.  `ios-deploy` makes
+installing and running these packages easy:
+
+    ios-deploy -b out/Debug/dm.app -d --args "--match foo"
+
+If you find yourself missing a Google signing identity or provisioning profile,
+you'll want to have a read through go/appledev.

-iOS
-===
-
-These instructions are historical and not explictly supported.  There is
-currently no explictly supported way to build Skia for iOS.
-
-The following has been tested on MacOS Yosemite with Xcode version 6.3.
-
-Quickstart
-----------
-
-First, install [XCode](https://developer.apple.com/xcode/).
-
-<!--?prettify lang=sh?-->
-
-    # Install depot tools.
-    git clone 'https://chromium.googlesource.com/chromium/tools/depot_tools.git'
-    export PATH="${PWD}/depot_tools:${PATH}"
-
-    # Get Skia.
-    git clone 'https://skia.googlesource.com/skia'
-    cd skia
-
-    # Create the project files.
-    python tools/git-sync-deps
-    GYP_DEFINES="skia_os='ios' skia_arch_type='arm' armv7=1 arm_neon=0" ./gyp_skia
-    # Build and run SampleApp.
-    xed out/gyp/SampleApp.xcodeproj # opens the SampleApp project in Xcode
-
-Prerequisites
--------------
-
-Make sure the following have been installed:
-
-  * XCode (Apple's development environment): required
-    * publicly available at http://developer.apple.com/xcode/
-    * add the optional Unix Tools to the install so you get the make command line tool.
-  * Chromium depot_tools: required to download the source and dependencies
-    * http://www.chromium.org/developers/how-tos/depottools
-  * You will need an Apple developer account if you wish to run on an iOS device.
-  * A tool such as [ios-deploy](https://github.com/phonegap/ios-deploy) is also useful for pulling output from an iOS device.
-
-Check out the source code
--------------------------
-
-See the instructions [here](../download).
-
-Generate XCode projects
------------------------
-
-We use the open-source gyp tool to generate XCode projects (and analogous
-build scripts on other platforms) from our multiplatform "gyp" files.
-
-Before building, make sure that gyp knows to create an XCode project or ninja
-build files. If you leave GYP_GENERATORS undefined it will assume the
-following default:
-
-    GYP_GENERATORS="ninja,xcode"
-
-Or you can set it to `xcode` alone, if you like.
-
-You can then generate the Xcode projects by running:
-
-    python tools/git-sync-deps
-    GYP_DEFINES="skia_os='ios' skia_arch_type='arm' armv7=1 arm_neon=0" ./gyp_skia
-
-Alternatively, you can do:
-
-    python tools/git-sync-deps
-    export GYP_DEFINES="skia_os='ios' skia_arch_type='arm' armv7=1 arm_neon=0"
-    ./gyp_skia
-
-Build and run tests
--------------------
-
-The 'dm' test program is wrapped in an app called iOSShell. The project for iOSShell is at out/gyp/iOSShell.xcodeproj.
-Running this app with the flag '--dm' will run unit tests and golden master images. Other arguments to the standard 'dm'
-test program can also be passed in.
-
-To launch the iOS app on a device from the command line you can use a tool such as [ios-deploy](https://github.com/phonegap/ios-deploy):
-
-    xcodebuild -project out/gyp/iOSShell.xcodeproj -configuration Debug
-    ios-deploy --bundle xcodebuild/Debug-iphoneos/iOSShell.app -I -d --args "--dm <dm_args>"
-
-The usual mode you want for testing is Debug mode (SK_DEBUG is defined, and
-debug symbols are included in the binary). If you would like to build the
-Release version instead:
-
-    xcodebuild -project out/gyp/iOSShell.xcodeproj -configuration Release
-    ios-deploy --bundle xcodebuild/Release-iphoneos/iOSShell.app -I -d --args "--dm <dm_args>"
-
-Build and run nanobench (performance tests)
--------------------------------------------
-
-The 'nanobench' test program is also wrapped in iOSShell.app. Passing in the flag '--nanobench' will run these tests.
-
-Here's an example of running nanobench from the command line. We will build with the "Release" configuration, since we are running performance tests.
-
-    xcodebuild --project out/gyp/iOSShell.xcodeproj -configuration Release
-    ios-deploy --bundle xcodebuild/Release-iphoneos/iOSShell.app -I -d --args "--nanobench <nanobench_args>"
-
-Build and run SampleApp in the XCode IDE
-----------------------------------------
-
-  * Run `git-sync-deps` and `gyp_skia` as described above.
-  * In the Finder, navigate to $SKIA_INSTALLDIR/trunk/out/gyp
-  * Double-click SampleApp.xcodeproj ; this will launch XCode and open the SampleApp project
-  * Make sure the SampleApp target is selected, and choose an iOS device to run on
-  * Click the “Build and Run” button in the top toolbar
-  * Once the build is complete, launching the app will display a window with lots of shaded text examples. On the upper left there is a drop down
-menu that allows you to cycle through different test pages. On the upper right there is a dialog with a set of options, including different
-rendering methods for each test page.
-
-Provisioning
-------------
-
-To run the Skia apps on an iOS device rather than using the simulator, you will need a developer account and a provisioning profile. See
-[Launching Your App on Devices](https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/LaunchingYourApponDevices/LaunchingYourApponDevices.html) for more information.
-
-Managing App Data
------------------
-By default, the iOS apps will look for resource files in the Documents/resources folder of the app and write any output files to Documents/. To upload resources
-so that the app can read them you can use a tool such as [ios-deploy](https://github.com/phonegap/ios-deploy). For example:
-
-    ios-deploy --bundle_id 'com.google.SkiaSampleApp' --upload resources/baby_tux.png --to Documents/resources/baby_tux.png
-
-You can use the same tool to download log files and golden master (GM) images:
-
-    ios-deploy --bundle_id 'com.google.iOSShell' --download=/Documents --to ./my_download_location
-
-Alternatively, you can put resources and other files in the bundle of the application. In this case, you'll need to run the app with the option '--resourcePath .'
