IOS will remain a top platform for mobile development alongside Android. It is now crucial for developers to closely monitor iOS app development trends as the total number of iOS applications has surpassed two million. Building a mobile app with a competitive edge can't be done any other way.
It's certain that some new trends and technology will dominate the iOS market this year.
These seven iOS development trends represent the direction that iOS app development is taking. To create a cutting-edge and contemporary application, all you have to do is understand them.
The following seven iOS development trends will shape the creation of iOS apps in the future
1. SwiftUI
A user interface toolkit that enables developers to create applications declaratively, SwiftUI is expected to be one of the major UI trends. Simply instructing SwiftUI on how want our user interface to appear and function is all that is required; the tool will determine how to make that happen when the user interacts with it.
Let's compare declarative and imperative user interfaces to have a better understanding of declarative UI. Developers exclusively utilized imperative UI prior to iOS 13. When a user presses a button in imperative UI, a function may be invoked.
However, imperative UI brings up a number of problems, especially those related to the idea of the state. Developers must monitor the status of their code and make sure the user interface appropriately represents that state.
Declarative UI, as opposed to imperative UI, enables developers to inform iOS of all potential app states simultaneously. To switch between the two states manually, they don't have to write code. When the state changes, SwiftUI automatically switches between UI layouts according to what its creators instructed it to display when a user completes a certain activity. Declarative UI is essentially this.
Additionally, SwiftUI may function as a cross-platform user interface layer that is compatible with watchOS, tvOS, macOS, and iOS. One layout framework and programming language may be learned by developers, who can then use their skills wherever.
2. Using Combine for Reactive Programming
Reactive programming: what is it? In essence, it is a paradigm for managing asynchronous data streams, or streams of events. Although it is not a novel idea in software development, it has gained popularity lately.
This is how it operates:
The iOS platform is used to reactive programming. To do so, developers might make use of many libraries. Developers were able to begin considering how events functioned and interacted with one another, as well as how this all impacted the business logic, thanks to iOS' reactive design.
Combine is useful in this situation. Apple developed this framework, which provides a declarative Swift API for handling data across time. In essence, it resolves the issue of nested closures that come up during the processing of async data. Combine gives programmers a high-level abstraction that imposes a paradigm that operates only in terms of data streams.
According to the Apple Developer Documentation, this is how it operates:
"Combine states that publishers will reveal values that are subject to change over time, and subscribers will be provided with those values by the publishers."
A type that may provide a series of values across time is declared using the Publisher protocol. Publishers have operators who republish the values that upstream publishers provide them.
A Subscriber, at the conclusion of a chain of publishers, responds to items as they are sent to it. Only when subscribers specifically ask them to do so do publishers provide values. By doing this, your subscriber code gains control over how quickly it gets events from the publishers with whom it is associated.
Combine is a tool that developers may use to aggregate the work of many publications and manage their collaboration. They get to create code as a consequence, which makes it simpler to comprehend and maintain. Additionally, Combine enables us to concentrate the event-processing code and remove issues such as convention-based callbacks and nested closures.
3. The Mac Catalyst
More developers will use Mac Catalyst to convert their iPad applications into native Mac programs. Apps may share the same project and source code thanks to Mac Catalyst. Because of this, it's now simpler than ever to add new features and convert an iPad app's desktop-class functionality for Mac.
The most recent version of Xcode 11 is now all you need. You can develop a native Mac application and then add more functionality by checking the "Mac" option in the iPad app's project settings. You can make changes to the code in one location since the two applications will share the same project and source code.
Applications developed in this manner for Mac will operate natively and make use of the same frameworks, resources, and runtime environment as those developed specifically for Mac. Features for Mac desktop and windowing will be added by the tool. Additionally, it will adjust the keyboard and mouse's touch capabilities.
4. Security and privacy
Advancements in security mechanisms will continue to be a major topic in iOS development. Apple is well-known for its stringent regulations and sophisticated security measures that keep hackers out of its gadgets.
With a particular emphasis on privacy and security concerns, the firm wants to provide a secure environment for its app users. The goal is to increase overall security and stop data leaks and cyberattacks.
Given the recent revelations of hacking and data breaches, that makes a lot of sense.
For instance, Apple has implemented the ASWebAuthentication Session, which manages the site data and cookies for login. It enables devices to include password management applications using authentication services frameworks.
5. The Apple HomeKit
Another significant trend in iOS development this year will be Apple HomeKit. Developers may write actions to control accessories and customize them using the framework. With the help of HomeKit, applications may manage and coordinate home automation accessories from many suppliers, all of which are shown on a unified user interface.
Developers may use HomeKit to create applications that find automation accessories that work with HomeKit and add them to the database of cross-device home configurations. The data in the home configuration database may also be edited and seen. Additionally, HomeKit makes it simple for applications to interact with preset services and accessories so they can carry out tasks like turning on the lights.
Developing home automation applications will be lot simpler and safer with Apple HomeKit! Apple addressed a major problem with Internet of Things (IoT) deployments at this year's WWDC by announcing HomeKit in routers and more secure video from webcams with HomeKit support.
6. ARKIt, or Augmented Reality
Augment Reality (AR) is another important trend in iOS development. The world's biggest AR platform is called ARKIt. Anyone wishing to create an AR iOS app has to have ARKit 3 Reality Composer. RealityKit, a high-level augmented reality framework that greatly simplifies the process of creating AR applications, will also be helpful to developers.
People Occlusion is a feature in ARKit 3 that enables applications to find people and AR items and then appropriately occlude the area. Human movement is tracked via the Motion Capture function, which provides the AR scene with input. Additionally, the function can monitor up to three faces simultaneously and facilitates collaborative sessions. These capabilities make it simple for developers to include human movement into their products.
What more can developer teams get out of ARKit 3? Here are some other features:
Front and rear cameras may be used simultaneously, allowing you to utilize both cameras' face and world tracking features simultaneously.
Multiple face tracking: ARKit Face Tracking uses the TrueDepth camera (found on certain iPhone and iPad models) to monitor up to three faces simultaneously.
Developers may get together and create a collaborative global map more quickly thanks to the collaborative sessions functionality. You may create applications that provide shared augmented reality experiences (like multiplayer games) in this way.
Up to 100 pictures may be detected simultaneously.
The physical size of the picture is automatically estimated.
Improved item identification in complicated situations and more advanced 3D object detection. machine learning to identify planes in the surroundings more quickly.
7. Using Flutter to design iOS apps
Flutter combines the benefits of a native framework with cross-platform functionality to provide a new and more efficient method of developing mobile apps.
Flutter was formerly exclusive to Google products like Chrome and Android. However, when Flutter became a cross-platform framework, everything was different.
Dart, Google's proprietary programming language, served as the foundation for Flutter. Flutter may be used in iOS development as well since the programming language can compile to native iOS code. Its various capabilities, such as hot reload, increase efficiency. Flutter includes Bitrise for CI/CD.
iOS developers may utilize Cupertino widgets to create user interfaces. Despite Flutter's cross-platform nature, developers may design distinct user interfaces for iOS and Android applications.
