I had set the preferred rendering api to openGL for compatibility with my old MacBook when in the simulation environment. Which caused the error you had in the new M1. I removed this override and the error is gone.

It would be like any file, wouldn’t it? I’d probably setup a dedicated folder for the app’s ICloud drive and pick it up from there. Plus that interface allows the user to select it from anywhere on their drive. Look up UIDocumentPickerViewController.

I can’t tell from this. For me, random crashes in ARKit seem to always trace back to improper access to the main thread. A variable getting accessed on the main that is also being changed on another thread. 99% of the time it’s fine. But occasionally it collides with itself.

Are you monitoring the cameraDidChangeTrackingState? This is needed to deal with interruptions to the session and decide how to handle them.

You could just use GameCenter to manage this. User defaults is a convenient way of saving app settings in the app's sandbox. They don't remain if the user deletes the app. But if you save scores, progress, and achievements to their GameCenter account, those things stay with the account. I think there is no reason to roll your own system for this.

Oof. All that debugging and it was a misspelling of "metallic" on the metalness contents file. Well, I got some refactoring out of it.

Thank you for the reply. I'm not too familiar with how this forum works despite how long I've been a member. I had tried to add a comment yesterday to explain what I found but I don't see it anywhere. So that doesn't work how I thought it did. But my problem was due to a simple misspelling when setting the metallic contents. I just had it in my brain as being similar to another issue related to trying to match colors and so I didn't see the simple answer first. The viewer was using the file being dropped directly into the spot. So no spelling issues there. And yet the programmatic equivalent was effectively being set to nil. It is all working now. Thanks.

It's now mostly working. Still a few 500s. So either the issue wasn't me and resolved itself or the right person read the post a flipped a switch. I did make a change in getting the file size but I don't think that's it.

I would just save the value and update the achievement. When the new value is added update with Int(savedUnits/total * 100.0). savedUnit += 1 let valtest = ( saveUnit / 1000 * 100.0) GKAchievement(identifier: achievementID).percentComplete = Int(valtest) Given that 'Int' truncates the remainder, it won't prematurely award it.

I add a “Request Refund“ option through StoreKit. Accessible from a help menu. I’ve only noticed it used once and it didn’t require input from me.

There is an isSceneCaptured property you can monitor.

There is an option to submit a video for the review. I got rejected once because they thought my app was only running an animation and also because it didn’t use ARKit enough. So I made a video showing how the user is creating the animation and that ARKit is an option to help the user visualize solutions. I think they were more accustomed to AR apps being all AR environment. Regardless, the video seemed to clear up any confusion. They deal with a flood of apps and can’t spend all day figuring out one and it may be a topic outside their interest, so its good to make things fast and simple to understand.

You need a texture source as well. Mapping the UV to this custom mesh. SCNGeometry(sources: [vertexSource, normalSource, textureSource], elements: elementArray). Makes one appreciate Blender.

You can get it to work in SceneKit but not RealityKit? I misread the question and thought it was Scenekit related where I do have it working. The doors are animated although the orientation is wrong. Y-axis is up yet this is on Z. I haven't used realitykit enough. The error may be related to RealityKit catching this difference in orientation? Not sure why it would care though.

I‘m currently working on polishing my SceneKit game. I mainly stuck with SceneKit because I have years of experience working with it and thought I could compensate for any issues faster than learning something new. I even felt like it was a smart idea after Unity’s recent controversy. You can feel somewhat alone in figuring things out. If you want to cross platform, that’s a solid point for Unity. Mine is made for the iOS mobile platform in mind. So I didn’t care about that. That said, and especially if this flops hard, I might try a Unity or Unreal PC game next.
