One of the best comprehensive iOS course!
I’ve now been following both of the QuickChat-courses, and I can honestly say that it’s one of the best programming courses I ever took. The tutorial is well-explained, and the content is of high quality. Also, David always replies to private messages with help. Great work, I appreciate it!
Production level code provided and all creation process showed step by step very thoroughly. As for me – one of the best courses I ever met. This course differs from usual courses, because there’s almost ready full scale application provided, with plenty of features. I think the real price for such a source code is about thousands of dollars. And besides of code there’s step by step creation video. Thanks David!
Great tutorial! Anton Novoselov
Thanks David! This is a great class and perhaps one of the best for iOS development. Instructor is a very good teacher – a lot hinges on the quality of the teacher I gathered after comparing this iOS class to others – and learning and enjoying this class a lot.
My Review Blue Rocket
Every single word I say is from the bottom of my heart. First of all, the course is the most comprehensive instant chat on the entire Internet. For me, this course is priceless because nobody is as kind as David who is willing to share his knowledge and experience to his students. Second, David(the instructor) is so supportive and knowledgeable. I am new to Swift and ios. I have got two times errors so far. Every time I asked David to help, he always replied my message in 12 hours even sooner. He helped me to keep going and learning. I have taken 7 courses before this one, he is definitely most supportive instructor I have never ever met!!!!!! I will follow his course. I am so glad to become his student. I enjoy his course. All in all, Thank David for providing us this such wonderful course and knowledge.
Great Tutorials! Jason Derulo
Okay, so this is honestly the best course the I have found on Udemy. Everything is so in depth and David is so clear on everything. I will say, you do need to know your way around Xcode, and definitely some background in Swift. Basic debugging will be a huge help if you run into any kind of problem. I will always recommend this course to anyone who tells me they are learning to make something real and amazing. I have learned tons of new things. I even learned some neat tricks that I thought weren’t possible on iOS. So this is just amazing.
Honest Review! Chris Bonneau
The instructor (David) has done an excellent work 1. He has explained each and every line of code in great detail. For eg. While explaining saving video file to local storage he explained the arguments of “write()” function, such as “atomically” & why it needs to be “true” (“true” creates temp file before saving to local storage. And before saving to local storage it checks if there already exists a file with the same name. If there is a file with the same name then atomically doesn’t overwrite) 2. He explained closures (or callbacks) in great detail (eg.if you are accessing property from within the closure then it should be accessed using “self” keyword) 3. Downloading video in background queue & once its finished, then return the downloaded video file to main queue. 4. Capturing thumbnail image from video is one of the toughest topic, but he explained every step in a very simple manner. 5.When we observe events in firebase & once we come out of view controller, then all observers for that view should be removed. 6. David, provides incredible & outstanding support. He is very active in the course Q&A section & answers questions with clarity & encouragement. 7. I give this course my unqualified recommendation.
One of the best course i took. Sachin Raut
QuickChat 2.0 is very useful to me. I spent a month to watch the course video and typed every line of the source code. I learned a lot from this course, especially how to use Firebase as a backend for a chat app. This course enhance my skills of the swift programming language.
