Extremely useful app

If you work with Core Data as a developer, you should buy this app. It makes it *so* easy to open up your store and inspect or edit the data.

I had been using a generic SQLite app for years to do this, but it was frequently difficult to interpret dates, read the contents of text fields, or inspect binary fields. Core Data Lab handles all these use case perfectly. It also tracks changes live, highlighting the updates your app is making to the store!

I've contacted support a couple times to suggest additional features, and they've always been very responsive. My experience with this app has been great, and nobody should hesitate to get it. There's a free trial version on the developer's website if you're not sure yet, but I bet you'll love it.

Incredibly useful, responsive developer

My app's entire data model lives in Core Data. Core Data Lab has proven itself to be incredibly useful during development over the past year in navigating relationships between the 14 inter-linked entity classes. I've also found Core Data Lab's display of images really helpful.

When I've discovered an issue with Core Data Lab, the developer has been both very responsive and helpful. I highly recommend both the app and the developer.

Must Have Tool for Core Data Work

If you are developing a app that uses Coire Data and you do not have this app, your missing out.
Allows me to create views that hit Core Data without writting the service api first.

Have saved so much time, I used to use Core Data editor back in the day but that does not work anymore. Glad I found this. Well worth the money
