Adding CloudKit sync to your SwiftData app? Small mistakes in your data models can cause frustrating runtime crashes and sync failures. Learn the critical requirements CloudKit enforces: why every property needs a default value, which delete rules actually work, how to set up relationships correctly, and why you should create your CloudKit container early—even if you're starting local-only. Get these fundamentals right and save hours of debugging.
