TESTIMONIALS

As an Android Developer I know about the challenges you will face when developing software for mobile devices. Therefore I can say with certainty that this training covers all the essentials you will need to start working on your iOS app. In addition you will also learn how to avoid common pitfalls as well as evaluating your solutions and analyze your software regarding various issues like performance or memory consumption. After taking this course I feel confident starting to contribute to the iOS development in our company. - Tim Nowaczynski (Mobile.de), Germany

I had high expectations going in and the class exceeded them… I’m leaving with a much greater understanding of the iOS frameworks, the delegate pattern, and a better appreciation of Apple’s documentation. The full day of Networking & Core Data was unexpected, but invaluable hands on experience. Learning your approach to designing the data model for Core Data and your instruction on concurrency/GCD queues has made me less intimidated moving forward on these complex topics. The facility, provided lunches, and workbook were all great. I also appreciated the homework assignments! - Tom Edgar, Sw Eng, Texas

I attended the class with absolute zero iOS development experience. Now, only few days after the class, I’m developing my first apps with confidence. All thanks to Geppy’s unique way of teaching and his deep knowledge. The class gave me knowledge from the basics to the more advanced topics in 5 days. That’s incredible. It would had taken forever to learn all these topics by myself. I would definitely recommend this class to everybody who wants to learn iOS development. - Steffen Maabjerg, Sw Eng (Primesoft), Denmark

This is by far the best training I had in years. Geppy was very thorough and methodological in walking us from basic to complex pieces of iOS. At the end of this training, all my engineers walked out with confidence. - Mamallan Uthaman, Sw Eng Manager (Salesforce), California

I’m very skeptical about any trainings and always do professional development on my own. Geppy really impressed me by his deep knowledge and the course intensity. He answered several tough questions and covered important topics with all necessary details. I highly recommend Geppy and his team. – Olga Khylkouskaya, Sr. Sw Eng (Salesforce), California

As a senior engineer at Oracle, I have attended many enterprise and apps development training classes. Invasivecode's training was unlike any I have attended before - at the end of my training I was left with a solid exposure to iOS, Swift and Objective-C, many starter apps that we built from scratch in class and 3 months of tech support, which is simply awesome. This is one of those classes that's great for intermediate and beginner iOS developers alike. Geppy is an iOS expert and he was glad to share his expertise, experience and know hows about the intricacies of iOS and Swift. I'd recommend this class to anyone looking to get into iOS development! - Ackshaey Sigh, Sr. Applications Eng (Oracle), California

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 classes taught by Geppy. I have taken 3 specialized iOS training classes from him 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. - Wuthichai “Woody” Lee, PayPal, California

Geppy is an excellent instructor with extensive knowledge of the iOS SDK. The iOS course was very helpful in learning iOS app development using the iOS SDK. Prior knowledge of OOP concepts and Objective-C is needed for effective learning from this class. - Swati Das, Sr. Integration Engineer (PayPal), California

The instructors are experts in their field and the iOS training provided excellent coverage of both Objective-C and iOS programming fundamentals. It was very hands-on and gave me enough knowledge to continue learning on my own. Thank you Geppy and Eva! - Dennis Natochy, Senior Manager (PayPal), California

This is the best programming class I have ever taken. Geppy is very experienced in iOS development and has managed to transfer his knowledge to us in a very interesting and organized way. The post-training assignment is more work for him, but extremely beneficial to the trainees. Working on the assignment reinforced tremendously what I learned in the class. Now I’m definitely more confident in my iOS programming capability. - Yifan Liu, Sw Eng (PayPal), California

The iOS training was just outstanding. I learned so much. - Adam Wolf, (Freelancer) Washington

Awesome. Bravo. Very helpful, willing to take time to answer questions and make sure concepts are grasped. Willingness to help after the course is a huge plus over all other iOS training companies. - Jon Grintz, Sr. Sw Eng. (Gracenote), California

Great, intensive iOS training. Geppy is a very knowledgeable and patient instructor. If your goal is to learn what is possible, and how to develop iOS apps as quickly as possible, and you are willing to work hard, this is the class for you. - Glenna Mayo, Sr. Sw Eng (Hightail), California

This iOS training is organized to teach the big, fundamental concepts through the use of these wide ranging topics. Giving you both a solid foundation in over arching concepts and practical knowledge on many parts of the SDK, both common ones as well as advanced. - Brian Young (Freelancer), California

When it comes to iOS development, Geppy is the man. His iOS training course is very intense but totally worth it - highly recommended. - R. M. Menon (Bucksprout), California

Talented people teaching valuable iOS training for developing relevant applications. - Joseph Adelaide, Sr. Sw Eng (NXP), France

My expectations about this iOS training class were really high. I can say they exceeded them! The teacher makes it really easy to understand developing for iOS. I came to the class with knowledge of iOS development, but thanks to the teaching methodology and the practice during the class, I got to an advanced level following the direction of the teacher. Additionally, the class is really personal, since the number of attendees is smaller in respect to other classes and you can learn more of what you need. - Juan Manuel Altamirano (Telefonica), Spain
