How to trigger vibration on Apple Watch OS 2?

I have been working with Apple Watch OS 2 for a while, but have not succeeded in triggering vibration on Apple Watch standalone app in Swift, using Xcode Version 7.0 beta 6 (7A192o).
All tutorials using vibration on iPhone in Swift look like:
import AudioToolbox
...
AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))
But I cannot import the AudioToolbox library.
I get the error:
Could not build Objective-C module "AudioToolbox"
Has anyone already found the way to do it?

You can generate haptic & auditory feedback, using:
WKInterfaceDevice.currentDevice().playHaptic(.Click)
'Click' is one of the 'cases' (types of vibration/beeps) that you can choose, cfr:
enum WKHapticType : Int {
case Notification
case DirectionUp
case DirectionDown
case Success
case Failure
case Retry
case Start
case Stop
case Click
}
This only works on the device, not in the simulator.

In Swift 3:
WKInterfaceDevice.current().play(.success)

I'm not a expert in WatchKit but I know that with Watch OS 2 you can use:
WKInterfaceDevice().playHaptic(.Notification)
The function playHaptic called on a WKInterfaceDevice instance engage the haptic engine in Apple Watch.
See more in the Apple documentation.

The Correct format is
WKInterfaceDevice.currentDevice().playHaptic(.Notification)
You can easily play the notification sound on watch

Function :
WKInterfaceDevice().playHaptic(.Notification)
Here you have :

WKInterfaceDevice.current().play(.failure)

AVCaptureScreen on Mac OS X 10.8

I have been trying to use the AVCaptureScreenInput class on Mountain Lion 10.8:
https://developer.apple.com/library/mac/#documentation/AVFoundation/Reference/AVCaptureScreenInput_Class/Reference/Reference.html
I downloaded the following sample code provided by Apple:
http://developer.apple.com/library/mac/#samplecode/AVScreenShack/Introduction/Intro.html
But when I ran it, it did not capture my screen. Instead it just showed a green screen where my screen was supposed to be.
Someone else noticed the problem here: http://openradar.appspot.com/12220970
Does anyone know how to work around this problem?

Doing the following "fixed" the problem. I don't know why:
defaults write com.apple.cmio CMIO_Unit_Input_ASC.DoNotUseOpenCL -bool YES
I filed a bug here: https://bugreport.apple.com/cgi-bin/WebObjects/RadarWeb.woa/41/wo/Dtr5y1Zj8ikA0Rjw6xYON0/6.83.28.0.9

Is there any way to create class without the help of mouse on Mac OS X?

I'm just working on Mac OS X Lion, and totally fresh facing with the IntelliJ IDEA. Is there any easy way to create a class just with the keyboard, without the help of the mouse?

The way I do it is
Navigate to the correct Java source directory in the Navigator. I do that by opening a class already in the module (⌘-O), then use Select Target, Project View (option-F1, 1) to jump to the right place in the Navigator.
Then the Generate Code command, both ⌘-N (Command-N) and control-option-N in the Mac OS X 10.5+ keymap, will open the New pop up where you can type J, A... to get Java

Where's my Mac OS X Cocoa Documentation?

I've probably done this to myself somehow, but in XCode 3.2.5, I can create both iOS and Mac OS X projects, but I only have documentation for iOS. When I click on that little "Home" dropdown, iOS is the only option.
I used to have more options for documentation.
So how do I get the Mac OS X docs? Do I have to re-install xcode or something?

Open the XCode preferences, and go to the «Documentation» tab.
From there, you can re-install (download) the documentation sets.
Documentation for Snow Leopard is:

Google for more atom feeds.. : )
