swift uiimage resolution code example

Example 1: increase the size of the image in Swiftui

struct ResizedImage: View {
    var body: some View {

            Image("myImage")
                .resizable()
                .scaledToFit()
                .frame(width: 200.0,height:200)

    }
}

Example 2: swift set image size

extension UIImage {

    func imageResize (sizeChange:CGSize)-> UIImage{

        let hasAlpha = true
        let scale: CGFloat = 0.0 // Use scale factor of main screen

        UIGraphicsBeginImageContextWithOptions(sizeChange, !hasAlpha, scale)
        self.draw(in: CGRect(origin: CGPoint.zero, size: sizeChange))

        let scaledImage = UIGraphicsGetImageFromCurrentImageContext()
        return scaledImage!
    }

}
