[Resolved] Can't install RMagick 2.13.1. Can't find MagickWand.h

In Mac OSX Sierra, to solve the issue, I had to do the following:

Clean:

brew uninstall imagemagick
brew unlink imagemagick

Then install:

ricardopereira

extension PHPhotoLibrary {

    typealias PhotoAsset = PHAsset
    typealias PhotoAlbum = PHAssetCollection

    static func saveImage(image: UIImage, albumName: String, completion: (PHAsset?)->()) {
        if let album = self.findAlbum(albumName) {
            saveImage(image, album: album, completion: completion)
            return
        }

Suppose we want to add support for a new iOS 8 API in our framework that replaces an older iOS 7 API. There are a few problems we might face:

1. The new API will crash if we call it on iOS 7
2. The new API won't compile if we build it using the iOS 7 SDK
3. The old API will raise a deprecation warning if built with a deployment target of iOS 8 and up

These three problems require three different technical solutions:

1. We can avoid calling the new API on an old OS version by using runtime detection (e.g. respondsToSelector:)
2. We can avoid compiling new APIs on old SDKs using the __IPHONE_OS_VERSION_MAX_ALLOWED macro
