Core Data specialists for your dedicated team.

Where Core Data fits in a long-term product team.

Core Data is an object graph manager more than a database wrapper, which explains most of the confusion about it. It tracks relationships and changes in memory and persists them, which makes it more powerful than a plain database layer and less forgiving about how it is used.

Threading is the rule that causes the most production crashes. Managed objects belong to the context that created them and must not cross threads; doing so produces failures that are intermittent and difficult to attribute. The framework provides the correct patterns, and the crashes come almost entirely from not using them.

What your dedicated team does with Core Data.

Core Data expertise is specific and not transferable from general iOS competence. A specialist who has not run a Core Data migration on a large user base will make a reasonable-looking decision that corrupts data for a subset of users.

Building that depth deliberately is what the Talent Success and Academy programme is for.

Common Core Data use cases.

• Complex related data on device Object graphs with relationships that a flat store would force the application to manage itself.
• Sync across a user's devices CloudKit integration so data follows the account across devices.
• Migrations on a large installed base Lightweight and staged migrations planned against real data volumes before release.

Adding Core Data skills to your team.

Core Data work sits with iOS developers in your dedicated mobile development team.

You can add Core Data capacity as one dedicated specialist or as part of a wider remote team, managed by a service delivery manager from our offices in Thailand. Companies hire dedicated developers this way under one agreement and one monthly fee.
