Preparation for your first app creation
Becoming an iOS App Developer
Xcode is an integrated development environment (IDE) with tools utilised by developers to build applications for macOS, iOS, WatchOS and tvOS. Xcode is more than a simple code editor: it incorporates a great variety of useful tools such as static code analysis (which can find bugs, including memory leaks, in the code before the compilation), excellent autocompletion support, and other debugging and performance instruments. Most iOS developers choose Xcode to write and compile code instead of using a number of disparate program to complete these tasks. Xcode is very convenient because it can be used for entire pap development.
Interface Builder is an application that is a part of Xcode that enables a developer to build interfaces using graphical interfaces. You can drag pre-built elements including buttons, sliders, tab bars and icons onto the interface of the future app and then customise them using different settings and colour palettes. Interface Builder is also used to define what happens when a user performs an action with an object on the page and which element in particular handles it, in other word, it connects actions with targets, as well as sets object bindings and controllers.
Not all developer use Interface Builder in their development workflow, especially the ones who build bespoke interfaces with custom object. However, our experts still recommend every prospective developer for Apple’s devices to learn the basics of Interface Builder and get acquainted with UIKit code that it generates. But go easy and do not count on Interface Builder too much, because it is essential to learn how to code interfaces from scratch, which is not possible if you use Interface Builder all the time. Interface Builder is a supplementary tool that allows you to create interfaces fast from ready-made component, but if you want to be an expert in iOS app development, you should know how to write user interfaces by hand.
iOS frameworks are important tools for any mobile developer. Application program interfaces (APIs) and programs allow developers to easily create applications that run on iOS and Mac OS X. Apple supplies developers with dozens of frameworks that allow them to build user interfaces, encrypt valuable data, program networking code, create graphical content, play media content, take pictures, memorise input data and passwords, display web pages and so on.
WIth all the frameworks provided by Apple, you begin the development process with a wide selection of tools and commands to build your application. Without these frameworks every development process will be like reinventing a wheel. Cocoa frameworks provide you with a lot of helpful resources that enable you to design complicated solutions with only a few lines of code. For instance, you can create an action to automatically find a file on the web by its URL address, parse it and upload it into a data structure - all in one line of code.
Other Tools for iOS
The tools described above are the primary ones to use for Apple development, but you should know that there are much more useful frameworks, environments and technologies available, you just have to find the ones that you like. If you want to start your app development project, it is high time you installed Xcode from Mac App Store and tried it out, poking around with different features and settings.
Benefits of a Mobile App
- Create a virtual extension of your business and stand out from the competition;
- Keep up to date with the digital business environment of today, which has been drastically changes with the introduction of smartphones into our daily lives;
- Stay abreast of the latest trends and evolve along with the ever-changing market;
- An app provides you and your customers with endless opportunities for research and analysis - for example, you can compare prices of your competitors to set the prices on your products;
- Gather information about your customers and competitors;
- Reach out to a whole new audience of smartphone and tablet users.Smartphones are the primary tool that enables the customers to get information about businesses, so be where your customers are.
Programming iOS Applications
- Function — var name = Mary.getName();
- Variable — var x = 7;
- Array — var things = array("good", "bad");
- Conditional — if (x == 25).
