Images.xcassets copies all the images in the kit and it mixes with other images, better follow the instructions in the image below

By adding a folder with the Create folder reference option, we will actually create a folder in the main set with its contents, and all your images will be divided. And using the following code, you can access all the images.
NSString *dirPath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"images"]; NSError * error; NSArray * images = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:dirPath error:&error];
Hope this helps.
