Adding more security to protect user data
Security and privacy are becoming more and more important to App users. A trustworthy chat application is therefore obliged to protect it's user data to the best of its abilities.
In a completely new section you are going to learn how to use ACLs (Access Control Lists) and Roles to protect your users' data.
1,5 h new video material
Since this is a community course, the requests of the participants resulted in 1,5 h of additional video material.
A Community Course
This course is all about communication. We are going to create an awesome Chat App that will include features like push notifications and real time updates.
This course is also completely about you. When you have completed this course you will have created a fully working Messaging App. However this will not be the end.
Share your ideas on how to enhance the Community Chat App even further in the Course Discussion Board. The course community is going to vote for new features that should be implemented. For the most popular feature requests I am going to release new Videos every month.
After outlining the challenges we are facing when creating a messaging application we are going to compile all the resources we are going to need to create our CommunityChat App. Using Parse as a backend service, we will then start developing a possibility for users to login and register for the CommunityChat.
As important as a way to register to a messaging service is an intelligent way to find users that we want to talk to. So we will also implement a great search feature.
The core of our CommunityChat App is of course a great user interface for exchanging messages. After setting up a iMessage-like UI we will focus our efforts on efficiently loading and sending messages.
Since there is no way around a real time feeling when it comes to text messaging, we will add support for push notifications into our app.

Adding security features to the App
I wrote my first line of code at the age of 10 by creating the simplest form of a Hello World Application within the Visual Basic Editor of Microsoft Word. For many years, programming was completely about the journey for me.
Starting off with Visual Basic and earning money by creating Access Databases for many clients was nice, but not the driving force behind my wish to know more about creating software.
After switching to the Mac, I started developing with Java, C++, and later ActionScript 3.0. After school I used my expertise in different scientifically used big data applications. My work was all about visualisation of large amounts of data and therefore creating the best user experience possible.
Although I do love programming, I chose a different path for my professional carrier. By becoming an educator I could follow my second passion which is sharing knowledge. Today and especially since the release of the iPhone SDK in 2008 my interest in programming mainly is focused on creating iOS Apps for educational use and finding ways to create software that can be used in classroom, at universities and by students themselves to make learning a great experience. Although my passion lies in educational software, I am also doing client work from time to time, which does not only include the development of iOS Applications but also the implementation of different iOS development trainings.
