After working through Develop in Swift Tutorial - Collect, model and store data - GratefulMoments my project has multiple errors - all relating to ".insert". SwiftUI/GratefulMoments/GratefulMoments/Logic/DataContainer.swift:42:21 Instance method 'insert' requires that 'Moment' conform to 'PersistentModel' I am wondering if this is because I am using Xcode Versionn 27.1 and the tutorial reuires some form of update?
