iNVASIVECODE

This is really a great class, and you can learn a lot from it whether you are a complete beginner to iOS, or already an intermediate developer. Here are my thoughts after doing the 1 week class in SF:

Pros:

-Geppy (the instructor) knows iOS very well. He has worked with iOS/OS X for more than 10 years and can answer any possible question you have.

-Hands on learning. While there is some lecturing to explain concepts, a decent portion of the class is spent typing code, which is really the best way to learn.

-Lots of examples. As a lot of the time is spent writing code, this means you can use these examples to look back on later and study

-The most important topics in iOS covered: MapKit, Core Location, Core Animation, Networking, Core Data, UIKit and more

-Geppy does a very good job of explaining the iOS infrastrucutre behind the scenes. Meaning, not just typing code that can be copy and pasted, but WHY things are done the way they are. For example, he explains why the delegation pattern is so common in iOS, why Swift (usually) uses pass by value as opposed to the Objective C pass by reference, amongst other things. He does a good job of explaining the "world of iOS" and the Cocoa Touch frameworks that largely compose it, so that you understand the code you're writing, not just copying it.

-The instrcutor was very willing to help. Any time someone had a problem, he would go to their computer and personally help them 1 on 1 with the issue. 

Cons: 

-It was only 1 week. The training really is very intense, and there is a lot to take in. Class was 9-12, Lunch usually 12-12:45, and then class 12:45-5:30/6. There was also 2 additional ~10 minute breaks in the morning and afternoon. For me, the hours were really long. I woud have preferred it to last 1.5 or 2 weeks instead of just the 1 week, but I understand they have their own projects and things to do at the company, so time is an issue. 

Don't get me wrong, I'm glad it was really intense and that I coud learn a lot, I just felt the days were a little long. But that's really the only con out of everything. Overall a great experience, and I would certainly recommend it to any beginner-intermediate iOS developer who really wants to further their education in iOS.

If you would like to truly understand the nuts and bolts of Objective-C and Swift programming languages and learn how to design a scalable iOS application, you have to take iOS training classes taught by INVASIVECODE. I have taken 3 specialized iOS training classes and as a result, I have a much deeper knowledge of Core Data, Core Animation, UI Design, and Instruments. iNVASIVECODE iOS training classes are not merely listening to abstract theories, but actually hands on. Geppy answered many Objective-C and Swift questions that we students had and was very patient with our learning. Above all, I am very pleased with the classes and will continue to take more other classes from him.
