ios – Find image size and optimise in Swift



In my application, I’m using YPImagepicker for selecting images from library and camera. I want to know image size in MB after selecting the pictures or capturing a photo. Task is to convert the images into data and send to backend via REST API. As of now we are limiting images into 5. So I want to see the size of every images if it is more than 1 Mb need to compress into 1mb.

let imgData = NSData(data: image.jpegData(compressionQuality: 1)!)
var imageSize: Int = imgData.count
print("actual size of image in KB: %f ", Double(imageSize) / 1024.0 / 1024.0)

the above sample I have used to check the size of the image but I’m not seeing the correct file size. For eg, I’m capturing one photo through app and it is getting saved in album when I check the image size it shows 3.4 MB in photo detail but in code I’m not getting the same size. What is best way to achieve this?
