I'm sorry but your lib is still crashing... This time in func blurEffect(boxSize: CGFloat) -> UIImage!

 <Error>: CGBitmapContextCreate: unsupported parameter combination: set CGBITMAP_CONTEXT_LOG_ERRORS environmental variable to see the details

Printing description of image:
(UIImage) image = 0x00007fb9a3f083b0 {
  NSObject = {
    isa = 0x00007fb9a3f083b0
  }
  _imageRef = 0x00007fb9a3d45880
  _scale = 1
  _flipsForRightToLeftLayoutDirection = false
  _traitCollection = 0x00007fb9a3d41d70
  _imageAsset = nil
}

boxSize is 20 and the image {373, 303}
