Hope will help you

extension String {
    public func isImageType() -> Bool {
        // image formats which you want to check
        let imageFormats = ["jpg", "png", "gif"]

        if URL(string: self) != nil  {

            let extensi = (self as NSString).pathExtension

            return imageFormats.contains(extensi)
        }
        return false
    }
}

This answer asks the framework to check the filename extension.

#import <MobileCoreServices/MobileCoreServices.h>

// ...

+ (BOOL) urlIsImage:(NSURL*)fileUrl
{
    if (fileUrl) {
        NSString *extension = fileUrl.pathExtension;
        if (extension && extension.length > 0) {
            CFStringRef uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, (__bridge CFStringRef)extension, NULL);
            return uti && UTTypeConformsTo(uti, kUTTypeImage);
        }
    }

    return NO;
}

Check The extension of the url by following code:

NSString *stringURL = @"http://...";
NSURL *url = [NSURL URLWithString:stringURL];
NSString *path = [url path];
NSString *extension = [path pathExtension];

if your extension is mp4 or mov it is video else if it is jpg, jpeg,png etc , it will be image

Please try this one:

 extension String {

        public func isImage() -> Bool {
            // Add here your image formats.
            let imageFormats = ["jpg", "jpeg", "png", "gif"]

            if let ext = self.getExtension() {
                return imageFormats.contains(ext)           
            }

            return false
        }

        public func getExtension() -> String? {
           let ext = (self as NSString).pathExtension

           if ext.isEmpty {
               return nil
           }

           return ext
        }

        public func isURL() -> Bool {
           return URL(string: self) != nil
        }

    }

import MobileCoreServices

    func mimeType() -> String {
         let pathExtension = self.pathExtension
         if let uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension as NSString, nil)?.takeRetainedValue() {
             if let mimetype = UTTypeCopyPreferredTagWithClass(uti, kUTTagClassMIMEType)?.takeRetainedValue() {
                return mimetype as String
             }
         }
         return "application/octet-stream"
    }

    var containsImage: Bool {
        let mimeType = self.mimeType()
        guard let uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassMIMEType, mimeType as CFString, nil)?.takeRetainedValue() else {
             return false
        }
        return UTTypeConformsTo(uti, kUTTypeImage)
    }

    var containsAudio: Bool {
        let mimeType = self.mimeType()
        guard let uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassMIMEType, mimeType as CFString, nil)?.takeRetainedValue() else {
              return false
        }
        return UTTypeConformsTo(uti, kUTTypeAudio)
    }
    var containsVideo: Bool {
        let mimeType = self.mimeType()
        guard  let uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassMIMEType, mimeType as CFString, nil)?.takeRetainedValue() else {
               return false
        }
        return UTTypeConformsTo(uti, kUTTypeMovie)
    }
 }

if you are sure that the file can only be a photo or a video you can use this simple code:

if let data = try? Data(contentsOf: YOUR_LOCAL_URL) {
    if let _: UIImage = UIImage(data: (data)) {
        print("image!")
    } else {
        print("video!")
    }
}

Use import UniformTypeIdentifiers

extension URL {
    var isImageFile: Bool {
        UTType(filenameExtension: pathExtension)?.conforms(to: .image) ?? false
    }
}
