UIImageJPEGRepresentation has been replaced by instance method UIImage.jpegData(compressionQuality:)

ios swift swift4 ios12

The error is telling you that as of iOS 12 the old UIImageJPEGRepresentation function has been replaced with the new jpegData method on UIImage.

Change:

let imageData = UIImageJPEGRepresentation(image, 0.75)

to:

let imageData = image.jpegData(compressionQuality: 0.75)

Similarly, the use of UIImagePNGRepresentation has been replaced with pngData().

ios swift swift4 ios12

Just replace

guard let imageData = UIImageJPEGRepresentation(image, 0.75) else { return }

with:

guard let imageData = image.jpegData(compressionQuality: 0.75) else { return }

ios swift swift4 ios12

This error occurred in ios 12 and swift 4.2 version.

let image = UIImage()let imageData = UIImageJPEGRepresentation(image, 1)to:let image = UIImage()let imageData = image.jpegData(compressionQuality: 0.50)

you want to change like this. Please try this it's working for me.
