net maui folderpicker on iOS, return a path with access denied

Question

I am using FolderPicker to have a path where I can create a file.

on Android it returns a path that I can write to (till A10...)

in iOS it returns a path where I can't create a file. I have always "access denied".

Am I doing something wrong?

There are some permission I have to set on iOS to write a file?

Hello,

You cannot write files to this path by code directly.

If you want to write a file in the Files application in iOS platform.

Firstly, Enable iCloud capabilities. For more information, see Capabilities.

And Enable Share with Files app.

Then, if I have an image that in the /Resources/Image folder, I want to write it to the Files application

• Firstly, we can copy it to the application internal storage.

public async Task CopyFileToAppDataDirectory(string filename)
    {
        // Open the source file
        using Stream inputStream = await FileSystem.Current.OpenAppPackageFileAsync(filename);

       // Create an output filename
        string targetFile = Path.Combine(FileSystem.Current.AppDataDirectory, filename);
       // Copy the file to the AppDataDirectory
        using FileStream outputStream = File.Create(targetFile);
        await inputStream.CopyToAsync(outputStream);
    }

• Second, we can share this file to Files app. It will push a popup window, please choose Save to Files selection.

public async Task ShareFile()
    {
        string fn = "test.png";
        string file = Path.Combine(FileSystem.Current.AppDataDirectory, fn);
        await Share.Default.RequestAsync(new ShareFileRequest
        {
            Title = "Share text file",
            File = new ShareFile(file)
        });
    }

Best Regards,
