If I use the image before it is saved it is normal. But if I save it and use it later is is 90 degrees turned. How can I make sure it doesn't save sideways?

func saveEvent(_ center1: CLLocation, title2: String, imagePicked1: UIImage)
    {
        let data = UIImagePNGRepresentation(imagePicked1);///
        let url = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(NSUUID().uuidString+".dat")
        do {
            try data!.write(to: url!, options: [])
        } catch let e as NSError {
            print("Error! \(e)");
            return
        }
        let image11 = CKAsset(fileURL: url!)

        self.eventRecord.setObject(image11 as CKAsset, forKey: "Picture")
        let publicData = CKContainer.default().publicCloudDatabase
            publicData.save(self.eventRecord, completionHandler: { record, error in
                if error == nil
                {
                    print("Image saved")
                }else{
                    print(error!)
                }
        })
    }

If you need to save your PNG with correct rotation you will need to redraw your image if its orientation it is not .up. You can redraw it as follow:

extension UIImage {
    var png: Data? {
        guard let flattened = flattened else { return nil }
        return UIImagePNGRepresentation(flattened)
    }
    var flattened: UIImage? {
        if imageOrientation == .up { return self }
        UIGraphicsBeginImageContextWithOptions(size, false, scale)
        defer { UIGraphicsEndImageContext() }
        draw(in: CGRect(origin: .zero, size: size))
        return UIGraphicsGetImageFromCurrentImageContext()
    }
}
