Image share only on whatsapp in swift 3

Question

I want to share image only on whatsapp, but the code I use, shows other online share platform i.e. messenger & email.

Code I used:

    func share(shareText:String?,shareImage:UIImage?){

    var objectsToShare = [AnyObject]()

    if let shareTextObj = shareText{
        objectsToShare.append(shareTextObj as AnyObject)
    }

    if let shareImageObj = shareImage{
        objectsToShare.append(shareImageObj)
    }

    if shareText != nil || shareImage != nil{
        let activityViewController = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view

        present(activityViewController, animated: true, completion: nil)
    }else{
        print("There is nothing to share")
    }
}

and to share

    let imageToShare = UIImage(named: "05")
    share(shareText: "", shareImage: imageToShare)

You can not hide all the option that are showing in the UIActivityViewController because it depends on the content you are sharing and also installed app in your device, but you can hide most of it like all default options like this way:

let activityController = UIActivityViewController(activityItems: sharingItems, applicationActivities: nil)

    activityController.excludedActivityTypes = [
        UIActivityType.assignToContact,
        UIActivityType.print,
        UIActivityType.addToReadingList,
        UIActivityType.saveToCameraRoll,
        UIActivityType.openInIBooks,
        UIActivityType(rawValue: "com.apple.reminders.RemindersEditorExtension"), 
        UIActivityType(rawValue: "com.apple.mobilenotes.SharingExtension"),
    ]

    present(activityController, animated: true, completion: nil)

By adding some extra line to Mr. Patricks code I reduce the extra online sharing option that satified my need , If any one facing the same problem for those I want share that. I remove all other sharing option except WhatsApp using below code and it just shows WhatsApp and more option to share on screen . Thanks

 func shareImg(){

    let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    activityViewController.excludedActivityTypes = [
        UIActivityType.postToTwitter,
        UIActivityType.postToWeibo,
        UIActivityType.message,
        UIActivityType.mail,
        UIActivityType.print,
        UIActivityType.copyToPasteboard,
        UIActivityType.assignToContact,
        UIActivityType.saveToCameraRoll,
