i did a bunch of things but i think what did it was setting the minmum ios in unreal to 17 and then in xcode set it to 18 and set project format to xcode 16. i may have also changed the apple_SDK.json to include SDK 18 (see comment above). note that im able to send the app to app store connect but its still not shown up yet. i need to get through a bunch of plist warnings but atleast it gets past the upload proccess.
