Details

In this iOStraining course you will learn the basics to secure the code that is needed to develop iOS applications.

You will learn more about the input applications, testing, error handling, exeptions, network interaction and how to protect data in iOS apps.

Among subjects that covered are Objective-C, Swift, UIWebView, TCP, CF functions, NSURLConnection, XCTestCase, MD5, SHA, RNCryptor libary and far more.

Result

After completing this course you will be familiar with defensive programming for iOS applications.

Prerequisites

We recommend basic knowledge of programming iOS applications.

Course options

We offer several optional training products to enhance your learning experience. If you are planning to use our training course in preperation for an official exam then whe highly recommend using these optional training products to ensure an optimal learning experience. Sometimes there is only a practice exam or/and practice lab available.

Optional practice exam (trial exam)

To supplement this training course you may add a special practice exam. This practice exam comprises a number of trial exams which are very similar to the real exam, both in terms of form and content. This is the ultimate way to test whether you are ready for the exam.

Optional practice lab

To supplement this training course you may add a special practice lab. You perform the tasks on real hardware and/or software applicable to your Lab. The labs are fully hosted in our cloud. The only thing you need to use our practice labs is a web browser. In the LiveLab environment you will find exercises which you can start immediately. The lab enviromentconsist of complete networks containing for example, clients, servers,etc. This is the ultimate way to gain extensive hands-on experience.
