Presentation is clean and good. Exercises are totally guided, and don't actually cover the whole scope of the course.

Learned so much in this course. Looking forward to moving on to the next courses!

Very well explanation. However, a lot of Objective-c features are not covered.

Needs further explanations, good if you already have a programming foundation

Have no Chinese sub，most API can't use. Homework is not suit for teaching.

This course is very good and fantastic way to start the Objective-C.

It should definitely have more quizzes! At least one per week!

Its a great course, the only issue is that need to be update.

Its a good course for basic learning of Objective C

A very good and in-depth knowledge providing course

Such a great, and easy going course

The course is old at the moment

Nice starter !!

Great course

Very useful

Good one

I cannot sign up for the message board -- why can't we just use Coursera's built-in one like other classes do? Also, it would be a lot nicer if we didn't have to pay to even submit quizzes to get any feedback. I feel like I should only have to pay to get the certificate or maybe a final project review. Also, I don't really think all the intro to programming stuff should be in this class. It seems like it should be a separate class, really, like explaining what a function is. Objective C is big enough on its own without trying to teach C, too. The assignments aren't very inspiring, either, although I like how simple the first one was because it got me on my computer trying to do it the first day.

The course is fine for what it is, but it relates to an outdated version of XCode and iOS, and some of the key instructions don't apply verbatim and leave the student searching for a solution. The course needs updating. Also, peer grading is slow and ineffective. Finally, it is possible to do the assignments without paying attention to the core lessons of the course because the instructor shows sample code that does almost the entire assignment in each case. Also, the videos are slow for experienced programmers. Even at 2X playback speed I was bored. It was okay for me, but I am concerned a beginner might have a tough time.

The course is reasonable, but the lecturer is quite tedious to follow sometimes, especially when he tries to explain basic computer science concepts. Some of his implementations have questionable coding syntax and style. Also note that this was recorded in 2015, and has not been updated and that really starts to tell as you progress through the specialization, especially in later courses where APIs he uses have been deprecated.

It's an application develop course for total beginners who want to quickly develop a software, which may not be suitable for those who want to really get a whole picture of the obj-c language

Not very proper explanation of How to use Control key with mouse to set button properties.

No discussion forum

lacks updated information

Not to bad, but its hard

it is a little bit old
