How do I develop an iOS app that lets me send text to a arduino?

I have seen no good tutorials for actually making Bluetooth apps on playgrounds.

I’ve seen tutorials for mac but I only have an iPad.

Im really lost any help would be much appreciated.

I don’t even know how to structure an app in playgrounds, it’s different then in mac.
