About the Course

You will learn to extend your knowledge of making iOS apps so that they can securely interact with web services and receive push notifications. You'll learn how to store data securely on a device using Core Data. You’ll also learn to securely deploy apps to the App Store and beta users over-the-air. The format of the course is through a series of code tutorials. We will walk you through the creation of several apps that you can keep as a personal app toolbox. When you make your own apps after this course, you can bring in these capabilities as needed. When necessary we pop out of the code tutorials to talk about concepts at a higher level so that what you are programming makes sense. Upon completing this course, you will be able to: 1. Post Facebook, Twitter, Sina Weibo, Tencent Weibo messages to social media using single sign-on on behalf of a user. 2. Use OAuth 2.0 to securely authenticate to Instagram and retrieve photos on behalf of a user 3. JSON 4. Describe JSON’s syntax 5. Write well-formed JSON 6. Work with JSON data objects in Objective-C 7. Appropriately set the security settings for App Transport Security in iOS 9.0 8. Use http, https and https with perfect forward secrecy to fetch web resources 9. Obtain permissions to receive local push notifications 11. Write an app that can send and receive local push notifications 12. Obtain permissions to receive remote push notifications 13. Write an app that can receive remote push notifications 14. Authenticate using Apple’s cryptographic services such that the developer can use 3rd party infrastructure to send remote push notifications to their app. 15. Securely store data on the user’s device. 16. Authenticate using Apple’s cryptographic services such that they can deploy an app to the app store...

Very detailed course that contains lots of practice. Some information is changed for the current versions iOS and XCode, but despite this I like the course! Thank you.

Excellent intermediate level course for objectives C. Good approach to the course presentation. Introduces concepts clearly and then drives into actual implementation.

Too old in my opinion. Uses Objective-C, Xcode 7 with simulators running iOS 9 this should be highlighted in the course description since that's an important information anyone should know before enrolling.

I will look for more updated courses about iOS security on iOS 12/13 with Swift.

The material and videos are so poor, and low quality, I am happy to not have bought this course

Again this specialization seems to be a great number of courses, it is a shame it is not current and most of the information sought is out of date and doesn't work, so the learner has to go out and actually study ion his own to get current with the programming. That said, in my case I found that to be extremely satisfying, since I was able to learn the material better and help others at the same time. It made the course progress much slower than if the course was up to date. I urge Coursera to bring back this specialization and update the material. I did have a point in the second week when the material was just not working and impossible to find the solution online from other developers, but perseverance pays off and putting time in reading a lot of documentation on and got things working.

I forgot to mention on the 3 course Best Interface Design I was able to take a week off and get an app ready with all that I learned from these 3 courses and released it to the App Store.

Thanks for your time Prof P.

This was another excellent course in the iOS specialization by Prof. Don Patterson. However, Prof. Patterson's teaches students many important concepts prevalent in iOS apps, such as integration with various social networking applications, working with data in local on-device storage, and push notifications. Once again, I found Prof. Patterson's style to be very engaging (a most difficult task especially for online lectures) and the course materials to be well thought out.

Only one caveat though: The name of the course is a little misleading: there isn't much of a discussion about security features of iOS (I would have expected a course covering security in iOS to at least talk about using cryptography inside apps.)

I believe the professor has once again succeeded in walking through beginners through more advanced concepts like social media integration and core data. It's not so much the course that is amazing just because it's talking about iOS app development, but it's the teamwork of the professor and the app developer and their genuine commitment to high level and crystal clear tutorials and explanations. The professor never once skipped over anything. Each item is explained to a level of professional detail. In return, as an educator, I will publicly praise UC Irvine and its exceptional faculty member.

The content has a very good breadth component(covering json response handling,core data and push notifications.The very important components of iOS).All of them have been handled in suitable depth.Professor Don Patterson's diction and style of teaching is great.As I'm currently working as an iOS engineer, it is helping me a lot in expanding my skills.

I would say that prior programming knowledge would be a big advantage, otherwise it might become a copying exercise without necessarily knowing what you're doing. I like the fact that the videos show that not everything works smoothly in the sense that it's easy to make mistakes, even by Don :-)

Professor Patterson guides you through all the basics of Networking in iOS. The content is well structured and easy to understand. I highly recommend taking this course if you want to know how to use web services to fetch data and use core data for persistent storage.

Although the name of the course is a bit misleading, the content it covers is good and is worth the price you pay for it. Instructor is very informative and knows what he's talking about. Quizzes and assignments are a bit easy for my taste but thats a minor gripe.
