iOS method similar to GetExternalFilesDir?

[CodingOctocat]

Hi~ I'm a MAUI beginner, my program generates a lot of user data, so I choose to store the data in an external storage /Android/data/com.xxx.yyy/files:

string path = Android.App.Application.Context.GetExternalFilesDir("testFolder").AbsoluteFile.Path;

My App also needs to support iOS, but I don't know how to get a directory with the same concept. I think I really need a table comparing storage paths for Android/iOS.

I read the article: How many solution save local data on mobile for iOS Developer.

I think this is exactly what I want, but how do I use it in MAUI?

Saving Files to Disk
Saving files to disk is a common approach for storing large data sets, such as images, videos, or documents. iOS provides a variety of options, including saving files in the app’s sandboxed directories or using external storage providers like iCloud or Dropbox.
Advantages:
Suitable for storing large data sets.
Provides flexibility in organizing and managing files.
Allows easy sharing of files with other apps.
Limitations:
Requires managing file paths and directories.
Not designed for structured data storage.
May require additional effort for synchronization and backup.
Sample Code:

// Writing data to a file
let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("data.txt")
let text = "Hello, World!"
try text.write(to: fileURL, atomically: true, encoding: .utf8)

// Reading data from a file
let fileContent = try String(contentsOf: fileURL)

This is my solution, is it correct?

using Foundation;

namespace FireCamera.Helpers;

public static partial class StorageHelper
{
    public static partial string GetExternalCacheDir()
    {
        string path = NSFileManager.DefaultManager.GetUrl(
            NSSearchPathDirectory.CachesDirectory,
            NSSearchPathDomain.User,
            null,
            true,
            out var _).AbsoluteString!;

        return path;
    }

    public static partial string GetExternalFilesDir(string? folder)
    {
        string path = NSFileManager.DefaultManager.GetUrl(
            NSSearchPathDirectory.DocumentDirectory,
            NSSearchPathDomain.User,
            folder is null ? null : new NSUrl(folder, true),
            true,
            out var _).AbsoluteString!;

        return path;
    }
}
