iOS is an absolute powerhouse of an operating system that powers 43% of smartphones in North America. Along with Android, iOS has created a global duopoly of smart-device operating systems. The iOS ecosystem is built on a relatively new programming language called Swift!
Swift was released to the public in 2014 as a replacement for the older language of Objective-C. Apple launched Swift to be a modern, sleek, and developer-friendly option for faster & better programming.
Due to its prevalence in the world of business and mobile native apps. As an experienced iOS app development company, here is a complete basic guide into iOS mobile app development.
6 Basics Of iOS App Development
To get a better understanding of Swift you must grasp the fundamentals of iOS app development. The following 6 basics of ios mobile application development will help you understand the Swift language like a professional:
A syntax is of rules that govern the usage of words, numbers, symbols, etc. in a programming language that is supported. Just like many other modern coding languages, Swift draws its fundamental syntax structure from the C programming language. Thus developers who have worked with C previously will find many aspects of Swift syntax familiar.
Nonetheless, Apple has added multiple new features, improvements, capabilities, etc. into Swift. These syntax modifications differentiate Swift from C, making it easy to use for any iOS app development company & developer to use.
2. Programming Structure
In the Swift, programming language programming structure refers to the inter-component relation between multiple coding variables. A programming structure is a set of principles guiding the flow of information in a piece of code written in Swift.
A good iOS app development company is capable of using good programming structure management. Therefore when your programming structure is uncluttered and properly managed, it helps in fastening the development process.
3. Constants & Variables￼￼
In iOS app development a variable acts as a storage method that a program can control & manipulate. A variable is a data type that is capable of changing its value during a program’s execution. There are multiple forms of variables like; ‘double, bool, string, Int, Ulnt, etc.’
In mobile application development, a constant is referred to as a value that the developer cannot edit while the program is being executed. There are many types of constants like; ‘integer constant, a character constant, floating constant, etc.’ A constant is just like a regular variable apart from the fact that its value cannot be edited during execution.
4. iOS App Development Protocols
In the Swift programming language, a protocol is referred to as a method, process, properties, etc. that suit the functionality of a particular task. A protocol can be used by a class, structure, or enumeration to produce an actual implementation of previously defined values.
An experienced iOS app development company pays close attention to the implementation of all protocols of a development project.
5. Naming Conventions
After constants and variables come to the task of naming conventions. In the Swift programming language, the widely accepted naming convention is the process of camelCase. This naming convention starts with a lowercase letter followed by the corresponding word then an uppercase letter.
The following are a list of naming conventions that any good iOS app development company must know:
- Digits aren’t allowed at the beginning of a variable or constant name.
- Digits are allowed after the first character.
- An underscore character can start or be included in the start of a name.
- Symbols are case-sensitive.
By understanding Swift you get a better insight into the iOS app development cycle. Please note that the information presented above is a very basic breakdown of the Swift programming language and its applications.
A good iOS app development company will always share deep insight and information with its clients. This mutual sharing of information enables businesses to gain a better understanding of their products and services.
