} catch {
print(error)
}
}
}
} else {
// Cannot open whatsapp
}
}
}

Firstly you should download an image from URL
func data(from url: URL, completion: @escaping (Data?, URLResponse?, Error?) -> ()) {
URLSession.shared.dataTask(with: url, completionHandler: completion).resume()
}
What to do for this ->
let urlWhats = "whatsapp://app"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed) {
if let whatsappURL = URL(string: urlString) {
if UIApplication.shared.canOpenURL(whatsappURL as URL) {
// Set your image's URL into here
let url = URL(string: "https://your-image-url.com")!
data(from: url) { data, response, error in
guard let data = data, error == nil else { return }
DispatchQueue.main.async() { [weak self] in
let image = UIImage(data: data)
if let imageData = image.jpegData(compressionQuality: 1.0) {
let tempFile = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/whatsAppTmp.wai")
do {
try imageData.write(to: tempFile, options: .atomic)
self.documentInteractionController = UIDocumentInteractionController(url: tempFile)
self.documentInteractionController.uti = "net.whatsapp.image"
self.documentInteractionController.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)
} catch {
print(error)
}
}
}
}
} else {
// Cannot open whatsapp
}
}
}
