I am currently using IPhone 7 IOS to play Minecraft. However, I don't know why I can't play it with Bluetooth keyboards and mouse (when I press anything on the keyboard, there is nothing happen on the screen.) I went to do some research and I also found that there is not a mouse support for IOS bedrock too. I hope the new version update can fix this problem.
