Reply to SwiftData ModelContext Fetch Crashing
It seems to crash with any SwiftData related id, but it's fine when just using the primitive values let id = model.persistentModelID let descriptor = FetchDescriptor<cache>( predicate: #Predicate { $0.cacheOf.persistentModelID == id } // predicate: #Predicate { $0.cacheOf.id == id } or this ) let result = (try? self.modelContext.fetch(descriptor) // 💥 crash here! .first) return result

let id = model.persistentModelID let descriptor = FetchDescriptor<cache>( predicate: #Predicate { $0.cacheOf.persistentModelID == id } // predicate: #Predicate { $0.cacheOf.id == id } or this ) let result = (try? self.modelContext.fetch(descriptor) // 💥 crash here! .first) return result Some update on this! So turns out, I was fetching a model that was just created. The system can't find the model. I guess this was a cache miss in swiftData?! To Fix This: In your modelActor try? self.modelContext.save() basically, you want the modelContext to write into disk to create the persistentModelID Good luck!
