How to save a UIImage to Parse - swift

Question

I've taken an image and converted it to the jpeg format as such
let jpgImage = UIImageJPEGRepresentation(image1, 0.5)
Next I want to upload this image to Parse as a object part of a PFUser. When ever I try this I get the error
[Error]: The object is too large -- should be less than 128 kB
I don't know how to fix this error and just sign up the user. Thanks for any help or advice!

Objects are limited to 128kb as the error states, if your image is larger than that as it is you can choose to shrink it by using the function below.
func ResizeImage(image: UIImage, targetSize: CGSize) -> UIImage {
let size = image.size
let widthRatio = targetSize.width / image.size.width
let heightRatio = targetSize.height / image.size.height
// Figure out what our orientation is, and use that to form the rectangle
var newSize: CGSize
if(widthRatio > heightRatio) {
newSize = CGSizeMake(size.width * heightRatio, size.height * heightRatio)
} else {
newSize = CGSizeMake(size.width * widthRatio, size.height * widthRatio)
}
// This is the rect that we've calculated out and this is what is actually used below
let rect = CGRectMake(0, 0, newSize.width, newSize.height)
// Actually do the resizing to the rect using the ImageContext stuff
UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
image.drawInRect(rect)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return newImage
}
Use of the above function, you can resize your image as dynamics
dimension.Here as above code resize image of 200*200. By calling the
below function.
self.ResizeImage(UIImage(named: "yourImageName")!, targetSize: CGSizeMake(200.0, 200.0))
Source code from here.
So start by checking the image size by:
let sizeOfImage = image?.size
if let image = image {
let sizeOfImage = image.size
// Check the size here and resize if needed
}
