I didn’t see a CloudKit API in Swift to reset the development schema. So I made a SwiftUI button that runs a shell script of xcrun cktool reset-schema. But I couldn’t get it to work.

Error executing command: Error Domain=NSCocoaErrorDomain Code=4 “The file “🧨.sh” doesn’t exist.”

It does exist. But that’s ok. For now, I will click “Reset Environment…” in the CloudKit console and move on with my day.

I thought I’d have to define a CKRecord.RecordType along with a schema of field names and types before writing any data into CloudKit. But this is not necessary because a new RecordType is automatically created and modeled after the first instance of that particular type to be saved to the database.

First checkpoint. I have a shell of a Mac app with a CloudKit entitlement. It has a single button that creates a CKRecord object and saves it to the container’s public database. And in the CloudKit console, I see the new record type with schema defined along with the sample data!

I’m breaking ground on a companion Mac app today. It’s main job is to ingest JSON records, transform them to match a CloudKit schema and write them to a public CloudKit database.

And my neighbors are jack hammering their patio, which is bringing some good build something ambiance.

I’m building a reader app for images. The content is all similar (in the same subject domain) – but coming from multiple sources, each with it’s own schema. Some is available via API, but some is only via data dump.

Phase 1 is defining a common schema, fetching all the data, normalizing it into the shared schema, and then writing it all into a public CloudKit database.
