Fatal Error in Xcode during SwiftUI Tutorial

Hi, I'm learning to program with Swift using the tutorials on the Apple Developer site. I use the latest version of Xcode (14.3.1) and continuing in the "SwiftUI Tutorial" where I have to build an app called Landmarks, I get an error and it doesn't let me see the preview. It says there is an error in the "ModelData.swiftui" file but I can't figure it out, as I followed all the steps in the tutorial. If anyone had the same problem and can help me, I'd be very happy. Thanks in advance

Please show the code where the error occurs as well as the exact error message. Note that the file is ModelData.Swift, not ModelData.SwiftUI.
