@CMDdev I also am having the Codesign failed with non-zero exit code error. I tried editing with Xcode closed and than opened it, and it still doesn't work. When I try to go back to the previous version of the file it says Package resolution failed; see package resolution log for details. Do you have any suggestions?

For anyone who is having the same issue, I fixed it by using ballEntity.move() instead and putting nothing as the rotation - let newTranslation = SIMD3<Float>(0, 0, 1) let moveController = ballEntity.move(to: Transform(scale: simd_make_float3(1, 1, 1), translation: newTranslation), relativeTo: ballEntity.self, duration: 0.2) whereas previously (not working) I was doing this: let newTranslation = SIMD3<Float>(0, 0, 1) let moveController = ballEntity.move(to: Transform(scale: simd_make_float3(1, 1, 1), rotation: anchor.orientation, translation: newTranslation), relativeTo: ballEntity.self, duration: 0.2) Removing the rotation: anchor.orientation helped as my anchor was a bit tilted or moving.

We are supposed to create an Swift Playgrounds App

I found the problem, I put it in the wrong view. Silly me 🤪.

You can upload your app to Airport at https://airport.community . Airport is an App Store style app to find TestFlights. You can learn to create a public link at https://www.raywenderlich.com/10868372-testflight-tutorial-ios-beta-testing#toc-anchor-010

Can you please explain this better? I am a newb at swiftUI

No, @edford. What is the package wasn't added to the project. How do I add the package programmatically?

Is it possible to use UIReprsentableView

Why don’t you update to Xcode 12?

To build for iOS 14.0, you must have Xcode 12.0 or later installed!

@KMT, I am talking about the Transporter app from the Mac App Store, not ITMSTransporter command!

Can you put the QR code on Imgur and post a link?

Step 1. Go to Window->Devices and Simulators(⌘⇧2) Step 2. Select the Devices tab Step 3. Control-Click on your iPhone 7 and click "Unpair Device" Step 4. Unplug your phone Step 5. Plug it in again Step 6. If a dialog pops up, click Trust Step 7. Run your code again! It should work properly now!

Thanks!
