Convert Image to base64 and base64 to image (Encode and Decode Image to Base64) in Swift 5

base64toImage.swift

//Swift 5

//Encoding from image to base64
func convertImageToBase64String (img: UIImage) -> String {
    return img.jpegData(compressionQuality: 1)?.base64EncodedString() ?? ""
}

//Decoding from base 64 to image
func convertBase64StringToImage (imageBase64String:String) -> UIImage {
    let imageData = Data(base64Encoded: imageBase64String)
    let image = UIImage(data: imageData!)
    return image!
}

//Decoding using convenience initialiser in Swift 5

extension UIImage {
    convenience init?(base64String: String) {
        guard let data = Data(base64Encoded: base64String) else { return nil }
        self.init(data: data)
    }
