change line 210 to radius += 1 instead of radius += 1.0

Nice to have a Swift version, but do some time profiling and you'll find it is much, much slower than the Objective-C version. Setting a blur radius of 20 with no tint or saturation to my image takes 96 ms with the Objective-C version. This Swift version takes 1106 ms!

Even when I don't apply any blur, tint, or saturation, it's still slower. In my case, it takes 322 ms to apply no effect. This is compared to 36 ms from the Objective-C version with the same image and settings.

I'm using this method "UIImage(named: "TestBigImage")?.applyDarkEffect()" and when the view is going to be loaded, the iphone reboot.

Using the Obj C version, I'm able to apply a blur to the image like so:

effectImage = [self.image applyBlurWithRadius:15.0 tintColor:[UIColor colorWithWhite:1.0 alpha:0.2] saturationDeltaFactor:1.2 maskImage:self.image];

When I try to do the same thing with your Swift version, thus:

imageView.image = image.applyBlurWithRadius(15.0, tintColor: UIColor(white: 1.0, alpha: 0.2), saturationDeltaFactor: 1.2, maskImage: image)

.. I get an interesting effect, but it's definitely not a blur. Am I calling it correctly?

your example project has a trouble with build in iOS SDK 8.3 & xCode 6.3

I'm new in Swift , don't know about why this error occur.
This is just a report.

Thanks in advance.
