Excellent course

I've been 'messing around' with Mac programming for a long time (I'm a retired Windows programmer) and have been able to write iOS and MacOS apps using what I have learnt from that well known video site. However, I have always arrived at a point where I want to do something more significant and have failed to find a course that goes beyond the most basic of SwiftUI coding. That frustration ended when I took this course. The content goes well beyond anything I have watched before and delves into those more difficult areas that are important to a professional application. I am gratified to know that most of what I learnt previously is actually 'right' and am grateful to Karin for guiding me so well in those topics that I struggled with when learning alone. The course is not easy and will require you to think. That's a good thing. I now go away from this course with a list of changes that I need to do to my existing applications to implement features in a better way and to add usability that is so obviously lacking in my code. That alone makes this course worth every minute of the time it took and the cost. Thank you Karin for an excellent course.

This is exactly what I need. I've already mentally transitioned to using SwiftUI as my UI framework, since it is much more manageable for non-designers like myself, but I also want to use Core Data for any serious application collecting reasonable amount of data. CloudKit is also required, since I can not see any meaningful application not synchronizing between the several devices a user will typically have. Very good combination of technologies and right on the spot for me. The pace is a bit relentless but up to now the tutorial solved a couple of issues that I had with Core data. UI elements are very simplistic, but I guess the focus is on how to use Core Data in a serious application

So far so good, great to find a course that is focusing more on intermediate/advanced topics as there are tons of simple beginners courses that don't help much with creating a proper production app. Thanks!

This was a really good course. The project is complex and Karin presented a lot of advanced concepts both for macOS and iOS. For me the explanations in the iOS section were a bit less clear but there was still a lot of valuable information there. All in all a really good learning experience. Keep in mind that it is not a beginners course, but I think intermediate to advanced users will find it both interesting and beneficial to upgrading their skill set.

Frequently Asked Questions

In this project-based course, we'll be using Core Data to save and retrieve the user's data. Core Data is a powerful and flexible framework that allows us to manage and persist data in our iOS apps.

Throughout the course, we'll cover the basics of Core Data, including setting up a data model, creating managed objects, and working with fetch requests. We'll also explore advanced Core Data topics, such as implementing relationships between entities and filtering with NSPredicate. By the end of the course, you'll have a solid understanding of Core Data and how to use it to save and retrieve data in your iOS apps.

Core Data is a tool that helps app developers manage and store data in their iOS apps. It lets you create a model of what your app's data should look like, and then automatically saves and retrieves that data for you. With Core Data, you can create complex relationships between different pieces of data, and easily change your data model as your app evolves. Core Data also keeps track of changes to your data, so you can undo or redo them if needed. In short, Core Data helps developers focus on building the features of their app, while handling the hard work of managing and storing data in the background.

Whether or not to use Core Data in an iOS app depends on the complexity and requirements of the app. If the app involves managing a significant amount of data with complex relationships or requires advanced features like undo and redo, Core Data is an excellent choice. However, if the app requires only basic data storage and retrieval or is a small and simple app, using Core Data may be overkill.
Because you will build a complex note-taking app in this course, Core Data is a great choice..

Yes, Core Data and SwiftUI work very well together. In fact, Apple recommends using Core Data to manage data in SwiftUI apps. Core Data provides a layer of abstraction between your app's data and the underlying storage mechanism, which is essential for building scalable and flexible apps. Additionally, SwiftUI provides a declarative way of building user interfaces, making it easy to display data managed by Core Data.  

With Core Data and SwiftUI, you can create complex data models and relationships, and easily display that data in your app's user interface. SwiftUI has special features like the  @FetchRequest property wrapper which allows you to fetch data from your data store and display it in your app's UI. SwiftUI's built-in state management makes it easy to keep your UI in sync with changes to your data.

Overall, using Core Data and SwiftUI together is a powerful combination for building data-driven iOS apps. It allows you to focus on building great user experiences, while Core Data takes care of the complex data management tasks..

I have a Ph.D. in physicist, during which I started to love software engineering. Since I am also passionate about learning I started to build my own learning app. 

I am also very enthusiastic about design, which is a bit unusual for most physicists, I am putting a strong focus on the UI part.  In my courses, you will jump right into the subject and learn to design by actually designing.

From my former teaching experiences, I know that learning by trying is the most fun. So I will encourage you to use the tools I am showing you directly in your own projects. May they be small or grant.
