I've looked into a good number of articles on how to do a multipart/form-data POST on iOS, but none really explain what to do if there were normal parameters as well as the file upload.I have used the multipart/form-data POST on iOS & I had written the following code and it is uploading data but not image data - (void)postWithImage:(NSDictionary *)dictionary{ NSString *urlString = [NSString stringWithFormat:@"YourHostString"]; NSURL *url = [NSURL URLWithString:urlString]; NSString *boundary = @"----1010101010"; // define content type and add Body Boundry NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *body = [NSMutableData data]; [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; NSEnumerator *enumerator = [dictionary keyEnumerator]; NSString *key; NSString *value; NSString *content_disposition; while ((key = (NSString *)[enumerator nextObject])) { if ([key isEqualToString:@"file"]) { value = (NSString *)[dictionary objectForKey:key]; NSData *postData = UIImageJPEGRepresentation([UIImage imageNamed:value], 1.0); [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\";\r\nfilename=\"screen.png\"\r\n\r\n",value] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:postData]; } else { value = (NSString *)[dictionary objectForKey:key]; content_disposition = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key]; [body appendData:[content_disposition dataUsingEncoding:NSUTF8StringEncoding]]; NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:value options:NSJSONWritingPrettyPrinted error:&error]; [body appendData:jsonData]; //[body appendData:[value dataUsingEncoding:NSUTF8StringEncoding]]; } [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; } //Close the request body with Boundry [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:body]; [request addValue:[NSString stringWithFormat:@"%d", body.length] forHTTPHeaderField: @"Content-Length"]; NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"%@", returnString);}Can anyone please help me to get why image data is not uploading

We are creating a framework using Xcode and it is working fine with Xcode 12.1 but not working on Xcode 12.2 & above.
When the adopter app imports the framework file it shows the below error
The compiler that produced it, 'Apple Swift version 5.3 (swiftlang-1200.0.29.2 clang-1200.0.30.1)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3.1 (swiftlang-1200.0.41 clang-1200.0.32.8)

What does this mean in layman terms. I've been rejected from the store for this reason.Guideline 2.3.8 - Performance - Accurate MetadataWe noticed the app icon displayed on the device and the large icon displayed on the App Store do not sufficiently match, which makes it difficult for users to find the app they just downloaded.Specifically, the app icon displayed on the device is blank.Please see attached screenshots for details.Next StepsTo resolve this issue, please update the smaller device icon to match the larger App Store icon. When users search for your app on their devices, they should be able to recognize it from the icon on the App Store.ResourcesSince the large app icon will be displayed for your app on the desktop App Store, we recommend you provide an attractive, original icon that meets the following requirements for both iPhone/iPod touch and iPad apps:- 512px square (do not scale-up smaller artwork, as this could appear pixelated and blurry)- 72ppi, RGB, flattened, no transparency- High quality JPEG,TIFF, or PNG image file format. (ZIP-compressed TIFF files are not acceptable)You can also preview image files before submitting them by clicking the filename to view them in a separate window. Note that the small icon that you include inside your app's binary will be used on the iPhone, iPod touch, or iPad Home screen when installed. For more on icon sizes, please review App Icons on iPad and iPhone.For resources on creating eye-catching icons, you may want to review the App Store Product Page information available on the Apple developer portal.I have changed all the icons but still, the app got rejected. I am using icons created from https://makeappicon.com site.I have checked both icons are looking same. Why is app getting rejected?Suggest me another website for app icon creator.Please reply as soon as possible
