Include Asset Directory in iPhone game

I have a directory with text files that I need to read and store as game data. Using:

private void loadTextFiles()
{
	DirectoryInfo directoryInfo = new DirectoryInfo(Application.dataPath + "/" + myPath);
	FileInfo[] filesInfos = directoryInfo.GetFiles("*.txt");	
	
	foreach(FileInfo fileInfo in filesInfos)
	{	
            //Here I read each file
	}		
}

I can make it work like this in the editor, but the directory is not found in my iPhone. How can I achieve this?

Thank you. So what I understand is that I may be able to place a directory inside the iPhone but that would be manually or by using a post build script. But if I do that, those files won’t be encrypted and that is not feasible, because this is level data that a player could modify to cheat. I could use some encryption on my own but I don’t have the time for a solution like that.

Then, as I cannot use a directory to get files from there, what I think I can do is have a persistent xml file (within a txt file as I’ve read xml as TextAssets won’t work in iPhone) where I add the name of every level by code and then I use that to load every file by name using Resources.Load .
