Just to clarify ( it's not letting me edit for some reason ). I created a model on Reality Composer. I successfully tested this model by exporting it into my phone as a .reality file and it always worked, I was able to click on everything everytime, and it always displayed the whole "move your phone to detect a plane" intro. Now, I decided to import the model into an Xcode project and turn it into an app. I followed the instructions and it didn't work. The asset is not showing up on the phone. For test purposes, tested the basic app that Apple creates when you create a new AR App>chose SwiftUI and this time, the cube showed up but the instructions to move the phone didn't show up. So there must have been a change going on. I have many apps installed on my phone... including several of Apple's code test examples. I just opened the underwater example and the same thing happened, the 'please move your phone to detected the plane' thing didn't appear either... and in this particular case I installed the test app like 6 months ago and haven't touched the code at all. Something is going on please advise:)

Thank you for this. I have exactly the same issue you all have. Also, Apple did us a huge disfavor by not adding the code for the WWDC19 609 example. I have so many questions and it's super complicated to actually go ahead with it. They have games, I just wish there was ONE simple app that laid out the very basics.

Solved. Nevermind!
