    if let composer = TWTRComposerViewController.emptyComposer() {
        composer.setText("Check out this awesome app!")
        composer.setImage(UIImage(named: "your_image.png"))
        composer.delegate = self
        present(composer, animated: true, completion: nil)

2.3. Instagram Sharing

Instagram is a popular platform for sharing photos and videos. Although Instagram’s API has limitations compared to other platforms, you can still allow users to open Instagram with pre-filled captions and images. Here’s a basic implementation:

let instagramURL = URL(string: "instagram://app")!
if UIApplication.shared.canOpenURL(instagramURL) {
    let imageData = UIImage(named: "your_image.png")!.jpegData(compressionQuality: 1.0)
    let caption = "Check out this amazing image!"
    let writePath = try! FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true).appendingPathComponent("instagram.igo")
    try? imageData?.write(to: writePath, options: .atomic)
    let fileURL = URL(string: "file:///path_to_your_image.png")!
    let docController = UIDocumentInteractionController(url: fileURL)
    docController.delegate = self
    docController.annotation = ["InstagramCaption": caption]
    docController.uti = "com.instagram.exclusivegram"
    docController.presentOpenInMenu(from: self.view.frame, in: self.view, animated: true)
} else {
    // Instagram is not installed

2.4. LinkedIn Sharing

LinkedIn is a professional networking platform that allows users to share articles, images, and text updates. To integrate LinkedIn sharing, follow these steps:

Handle errors gracefully. If a user cancels sharing or there’s a network issue, provide clear feedback and options for the user to try again. Good error handling enhances the overall user experience.

4. Tracking Shares and Analytics

To measure the impact of social sharing in your iOS app, it’s essential to track shares and gather analytics. This data can help you understand user behavior and refine your sharing strategy. Here are some key metrics to track:

4.1. Share Count

Keep track of how many times users share content from your app on each social media platform. This metric provides insight into the popularity of your app’s content.

4.2. Referral Traffic

Analyze the traffic generated from shared links. Identify which social media platforms are driving the most traffic to your app and optimize your content for those platforms.

4.3. Conversion Rate

Measure how many users who clicked on shared content actually installed your app or performed desired actions within the app. This helps you assess the effectiveness of your social sharing strategy.

To track these metrics, you can use analytics tools like Google Analytics, Firebase Analytics, or custom event tracking within your app.
