SDK and version
SDK : Swift
Version: 10.33.0
Observations
- How frequent do the crash occur? Everytime
- Does it happen in production or during dev/test? Dev
- Can the crash be reproduced by you? Yes
- Can you provide instructions for how we can reproduce it? Change my primary key type from String to UUID. The migrationBlock is never called and the SDK crashes.

Steps & Code to Reproduce
I changed my primary key type from String to UUID
OLD:
public class MyClass: Object { @Persisted(primaryKey: true) public var id: String?
NEW:
public class MyClass: Object { @Persisted(primaryKey: true) public var id: UUID?
configuration:
schemaVersion: 3,
migrationBlock: { migration, oldSchemaVersion in
/// THIS IS NEVER CALLED
if oldSchemaVersion == 1 {
} else if oldSchemaVersion == 2 {
migration.enumerateObjects(ofType: MyClass.className()) { oldObject, newObject in
newObject!["id"] = UUID(uuidString: oldObject!["id"]! as! String)
}
}
}
