3 Design Pattern Types in Swift for iOS App Development

It has been almost 7 years now since we saw the inception of Apple’s own programming platform Swift making a foray into the app arena in 2014. There is no doubt about how powerful Swift has proved itself so far allowing any iOS application development company in Delhi to build versatile apps for iOS.

Inspite of its history of seven years into iOS application development in Delhi it is still relatively new for most developers out there in terms of understanding design patterns and how to put them to use. It goes without saying that choosing a design pattern has truly become a prerequisite with regards to developing applications that are secure, of high quality, and functional at the same time.

To help an iOS application development company start off well with the development process, let us discuss three design patterns to help developers tackle problems that might be encountered during the design and development stages.

However, before diving deep into the benefits, let us first understand the benefits brought to the table by so-called these swift design patterns.

The Benefits Of Swift Design Patterns

Since the design patterns are already tried and tested, no time is wasted in reinventing the wheel with a project type as there are varied solutions offered for different app development issues.

Design patterns have been successfully implemented against all kinds of bugs and errors so as to deal with all types of mistakes occurring within the architecture.

Instead of making the platform understand what kind of solution you strive for in order to solve a problem related to solution development, it can be simply implied what kind of solution you are looking out for and the right one would be presented in front of you.

Swift Design Pattern Types

Now let us look at the main part of our discussion i.e. common design patterns in Swift and how to get them implemented to deliver solutions.

• Behavioural

The category is meant towards commonly identifying the interaction taking place in between the associated entities so as to further have them implemented. The sub design patterns associated herein are visitor, state, strategy, observer, memento, mediator, iterator, command, template method, and chain of responsibility.

• Creational

The software design pattern creational in nature has to do with mechanisms related to object creation. Herein, it is meant to instantiate objects based upon a situation and the sub design patterns related to the same are prototypes, singleton, builder, abstract factory, and factory method.

• Structural

The simplification of design is the key here with the relationship realisation meant between objects and classes. The sub design patterns within this category are proxy, flyweight, composite, decorator, façade, bridge, and adaptor.

Why is it necessary to have design patterns in place?

Ask any iOS application development company and you would get to know how important a design pattern could be in delivering a specific solution to a particular problem. An app architecture completely depends upon the design pattern being chosen.

However, no matter how good iOS application development company in Delhi you are, implementing a design pattern into app architecture is no child’s play since it is not merely a copy-paste job. It is not a piece of code that you can take from one place to insert in another place, which you would normally do with open-source libraries or out-of-the-box services.

If you are already doing iOS application development in Delhi you would know better than a design pattern is a concept meant towards solving a problem. It's simply a template that directs one towards writing lines of code but it’s a challenge at the same time to get the template to accommodate the code.

Most of them are not even used due to the fact that its hard to remember when its time for actual implementation. Hence, we mentioned only three types to make things easier for you so that when next time you sit to pick the right design pattern type ideal for your app, you know what are the available options to choose from getting you started.
