-####Camera Manager
+# Camera Manager
+[![CocoaPods](https://img.shields.io/cocoapods/v/CameraManager.svg)](https://github.com/imaginary-cloud/CameraManager) [![Carthage compatible](https://img.shields.io/badge/Carthage-compatible-4BC51D.svg?style=flat)](https://github.com/Carthage/Carthage)
 
-V1.0.4 (16-Oct-2014)
-
-####About
-This is a simple swift class to provide all the configurations you need to create custom camera view in your app. 
+This is a simple Swift class to provide all the configurations you need to create custom camera view in your app.
+It follows orientation change and updates UI accordingly, supports front and rear camera selection, pinch to zoom, different flash modes, inputs and outputs.
 Just drag, drop and use.
 
-####Installation with CocoaPods
+Now it's compatible with latest Swift syntax if you're using any Swift version prior to 2.0 make sure to use one of the previously tagged releases.
 
-The easiest way to install the CameraManager is with: [CocoaPods](http://cocoapods.org) 
+## Installation with CocoaPods
 
-## Podfile
+The easiest way to install the CameraManager is with: [CocoaPods](http://cocoapods.org)
+
+### Podfile
+
+If you want Swift 3.0 syntax use:
 
 ```ruby
-platform :ios, '7.0'
-pod 'CameraManager', '~> 1.0’
+use_frameworks!
+
+pod 'CameraManager', '~> 3.0'
 ```
 
-####How to use
-To use it you just add the preview layer to your desired view 
+If you want Swift 2.0 syntax use:
+
+```ruby
+use_frameworks!
+
+pod 'CameraManager', '~> 2.2'
+```
+
+If you want Swift 1.2 syntax use:
+
+```ruby
+use_frameworks!
+
+pod 'CameraManager', '~> 1.0.14'
+```
+
+## Installation with Swift Package Manager
+
+The [Swift Package Manager](https://swift.org/package-manager/) is a tool for managing the distribution of Swift code.
+
+Add `CameraManager` as a dependency in your `Package.swift` file:
+
+```
+import PackageDescription
+
+let package = Package(
+    dependencies: [
+        .Package(url: "https://github.com/imaginary-cloud/CameraManager", majorVersion: 2, minor: 2)
+    ]
+)
+```
+
+## Installation with Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is another dependency management tool written in Swift.
+
+Add the following line to your Cartfile:
+
+If you want Swift 3.0 syntax use:
+
+```
+github "imaginary-cloud/CameraManager" >= 3.0
+```
+
+If you want Swift 2.0 syntax use:
+
+```
+github "imaginary-cloud/CameraManager" >= 2.2
+```
+
+If you want Swift 1.2 syntax use:
+
+```
+github "imaginary-cloud/CameraManager" >= 1.0
+```
+
+And run `carthage update` to build the dynamic framework.
+
+## How to use
+To use it you just add the preview layer to your desired view, you'll get back the state of the camera if it's unavailable, ready or the user denied access to it. Have in mind that in order to retain the AVCaptureSession you will need to retain cameraManager instance somewhere, ex. as an instance constant.
 ```swift
-CameraManager.sharedInstance.addPreeviewLayerToView(self.cameraView)
+let cameraManager = CameraManager()
+cameraManager.addPreviewLayerToView(self.cameraView)
 ```
 You can set input device to front or back camera:
 ```swift
-CameraManager.sharedInstance.cameraDevice = .Front 
-CameraManager.sharedInstance.cameraDevice = .Back 
+cameraManager.cameraDevice = .Front
+cameraManager.cameraDevice = .Back
 ```
 
 You can set output format to Image, video or video with audio:
 ```swift
-CameraManager.sharedInstance.cameraOutputMode = .StillImage
-CameraManager.sharedInstance.cameraOutputMode = .VideoWithMic
-CameraManager.sharedInstance.cameraOutputMode = .VideoOnly
+cameraManager.cameraOutputMode = .StillImage
+cameraManager.cameraOutputMode = .VideoWithMic
+cameraManager.cameraOutputMode = .VideoOnly
 ```
 
 You can set the quality:
 ```swift
-CameraManager.sharedInstance.cameraOutputQuality = .Low
-CameraManager.sharedInstance.cameraOutputQuality = .Medium
-CameraManager.sharedInstance.cameraOutputQuality = .High
+cameraManager.cameraOutputQuality = .Low
+cameraManager.cameraOutputQuality = .Medium
+cameraManager.cameraOutputQuality = .High
 ```
 
-And flash mode:
+And flash mode (it will also set corresponding torch mode for video shoot):
 ```swift
-CameraManager.sharedInstance.flashMode = .Off
-CameraManager.sharedInstance.flashMode = .On
-CameraManager.sharedInstance.flashMode = .Auto
+cameraManager.flashMode = .Off
+cameraManager.flashMode = .On
+cameraManager.flashMode = .Auto
 ```
 
+To check if the device supports flash call:
+```swift
+cameraManager.hasFlash
+```
+
+To change flash mode to the next available one you can use this handy function which will also return current value for you to update the UI accordingly:
+```swift
+cameraManager.changeFlashMode()
+```
+
+
 You can specify if you want to save the files to phone library:
 ```swift
-CameraManager.sharedInstance.writeFilesToPhoneLibrary = true
+cameraManager.writeFilesToPhoneLibrary = true
+```
+
+You can specify if you want the user to be asked about camera permissions automatically when you first try to use the camera or manually:
+```swift
+cameraManager.showAccessPermissionPopupAutomatically = false
 ```
 
 You can even setUp your custom block to handle error messages:
+It can be customized to be presented on the Window root view controller, for example.
 ```swift
-CameraManager.sharedInstance.showErrorBlock = { (erTitle: String, erMessage: String) -> Void in
-    UIAlertView(title: erTitle, message: erMessage, delegate: nil, cancelButtonTitle: "OK").show()
+cameraManager.showErrorBlock = { (erTitle: String, erMessage: String) -> Void in
+    var alertController = UIAlertController(title: erTitle, message: erMessage, preferredStyle: .Alert)
+    alertController.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: { (alertAction) -> Void in
+    }))
+
+    let topController = UIApplication.sharedApplication().keyWindow?.rootViewController
+
+    if (topController != nil) {
+        topController?.presentViewController(alertController, animated: true, completion: { () -> Void in
+            //
+        })
+    }
+
 }
 ```
 
 To shoot image all you need to do is call:
 ```swift
-CameraManager.sharedInstance.capturePictureWithCompletition({ (image) -> Void in
+cameraManager.capturePictureWithCompletion({ (image, error) -> Void in
 	self.myImage = image             
 })
 ```
 
 To record video you do:
 ```swift
-CameraManager.sharedInstance.startRecordingVideo()
-CameraManager.sharedInstance.stopRecordingVideo({ (videoURL) -> Void in
+cameraManager.startRecordingVideo()
+cameraManager.stopVideoRecording({ (videoURL, error) -> Void in
 	NSFileManager.defaultManager().copyItemAtURL(videoURL, toURL: self.myVideoURL, error: &error)
 })
 ```
