📸 How to Save Pictures to Your iPhone Photo Library? 📲

So, you've just generated an awesome image using your program, and now you want to save it to your iPhone's photo library to show off to the world. But how do you do it? Don't worry, we've got you covered! In this guide, we'll walk you through the steps to save pictures to your iPhone photo library, whether they come from your camera or not. Let's get started! 🚀

💡 Understanding the Challenge

Before we dive into the solutions, let's understand the challenge at hand. The iPhone has a system photo library where all the images and videos you save are stored. To save your pictures programmatically, you'll need to interact with the iOS Photos framework.

📷 Saving Pictures from the Camera

If your image was captured using the iPhone's camera, we have good news for you! Saving it to the photo library is as easy as it gets. Here's how you can do it using Swift:

import Photos

func saveImageToPhotoLibrary(image: UIImage) {
    PHPhotoLibrary.shared().performChanges({
        PHAssetChangeRequest.creationRequestForAsset(from: image)
    }) { success, error in
        if success {
            // Image Saved!
            print("Image Saved to the Photo Library")
        } else {
            // Something went wrong
            print("Error saving image: \(error?.localizedDescription)")
        }
    }
}

In the above code snippet, we import the Photos framework and define a saveImageToPhotoLibrary function that takes an image as a parameter. Inside the function, we use PHPhotoLibrary to perform changes (saving the image) and handle the success or error using the completion handler.

🖼️ Saving Images Not Captured from the Camera

Now, what if your image wasn't captured using the camera, but generated programmatically by your app? No worries, we've got a solution for you too! Here's what you need to do:

import Photos

func saveGeneratedImageToPhotoLibrary(image: UIImage) {
    if let album = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .any, options: nil).firstObject {
        PHPhotoLibrary.shared().performChanges({
            let albumChangeRequest = PHAssetCollectionChangeRequest(for: album)
            let creationRequest = PHAssetChangeRequest.creationRequestForAsset(from: image)
            albumChangeRequest?.addAssets([creationRequest.placeholderForCreatedAsset!] as NSArray)
        }) { success, error in
            if success {
                // Image Saved!
                print("Image Saved to the Photo Library")
            } else {
                // Something went wrong
                print("Error saving image: \(error?.localizedDescription)")
            }
        }
    }
}

In the code above, we fetch the first available album from the PHAssetCollection and then perform the changes required to save the generated image to that album.
