Sharing Videos to Instagram Using Swift 4.2 and Xcode 11.3

Are you a developer looking to integrate video sharing capabilities to Instagram from your iOS application? If you're using Swift 4.2 and Xcode 11.3, you're in the right place. In this guide, we'll guide you through the process of sharing a video to your Instagram feed successfully. We'll address the common issues developers face, including URL scheme configurations, and provide a step-by-step solution to get you up and running.

Understanding the Problem

A user reported a problem when they attempted to share a video to Instagram using their Swift code. While the code seemed correct, the user encountered a persistent issue: the UIApplication.shared.canOpenURL method was returning false. This was likely due to incorrect URL schemes configured in their project settings, resulting in the app being unable to recognize the Instagram application installed on their device.

The Solution: Steps to Share a Video

Let's break down the solution into simple, actionable steps:

1. Modify URL Schemes in info.plist

A crucial aspect of iOS development when working with URLs is to ensure that your app can communicate with external applications like Instagram. For this, you need to set up the URL scheme correctly in your info.plist file. Here’s how:

Open your project in Xcode.

Navigate to your project’s target settings.

Go to Info URL Types.

Instead of adding instagram://library, simply add instagram as your URL scheme.

By modifying it to just "instagram", you're allowing your app to open Instagram without any additional path that might cause issues.

2. Fetching Video Assets

The provided Swift code contains a method to fetch the latest video asset from the user's photo library. Here’s a revised version of the code snippet for clarity:

3. Testing the Functionality

After implementing the changes above, do the following to ensure everything works smoothly:

Build and run your application on a real device (Instagram does not work in the simulator).

Ensure that you have the Instagram app installed and you are logged in.

Test sharing a video by invoking your sharing function.

Common Issues and Tips

Check for Instagram Installation: Always implement checks to see if the Instagram app is installed to avoid crashes.

Debug URLs: If the app still cannot open Instagram, confirm that the URL format is correct and the Instagram app permissions allow opening from other apps.

Conclusion

By carefully modifying your URL scheme and ensuring the correct implementation of fetching and sharing videos, you can easily integrate Instagram sharing into your iOS app using Swift 4.2 and Xcode 11.3. Following these steps will help you avoid common pitfalls and enhance your app’s functionality.

Remember, effective debugging and testing are essential components of successful app development. Happy coding!
