Native IOS

Native iOS and Android mobile applications have operating system-specific features. Apple and Google recommend using platform-standard navigation controls such as page controls, tab bars, segmented controls, table views, collection views, and split views whenever possible.

The majority of apps in Apple's App Store are written in the Objective-C programming language, and developers typically use Xcode to create them. Native iOS apps use Swift or Objective-C, while native Android apps use Java.

Android

Native Android App Development is the process of creating apps using traditional app development methods. Traditional app development entails creating apps for specific devices or platforms. There are currently only two major app software providers on the smartphone market. They are iOS and Android, respectively. So native apps are apps designed for either of the two software platforms that only work on the device for which they were designed. When using native mobile app development, the app is built and optimized for a specific platform. As a result, the app has impressive performance. Native apps are fast and responsive because they are built for a single platform and include their core programming language and APIs. As a result, the application has become significantly more efficient. 

Flutter

Flutter is Google's UI toolkit for creating beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Flutter is open source and free, and it is used by developers and organizations all over the world. For fast performance on any device, Flutter code compiles to ARM or Intel machine code, as well as JavaScript. Dart, a simple object-oriented programming language, is used to create Flutter apps. Flutter's central concept revolves around widgets. The entire UI is composed of various widgets, each of which defines a structural element (such as a button or menu), a stylistic element (such as a font or colour scheme), and a layout aspect (such as padding), and so on. 

React Native

React Native is a Facebook open-source framework that uses a declarative programming paradigm to create native JavaScript mobile apps. React Native combines the best aspects of native development with React, a top-tier JavaScript library for creating user interfaces. It was successful in assisting the developers in creating a stunning mobile app for the social media platform. React Native bridges the gap between web UI components and their native counterparts. The most obvious advantage is that you don't have to create two separate apps for each platform. React Native is simple to learn if the developer is familiar with JavaScript or React. React Native supports cross-platform development. In general, there are significant differences between Android and Apple apps

Swift

Swift is the successor to the C and Objective-C programming languages. Lowlevel primitives such as types, flow control, and operators are included. It also includes object-oriented features like classes, protocols, and generics, providing Cocoa and Cocoa Touch developers with the performance and power they require. Swift is a free and open-source programming language that is available to a large number of developers, educators, and students. Swift is a fast and efficient programming language that can be seamlessly integrated into existing ObjectiveC code. As a result, developers can write safer, more reliable code, save time, and create richer app experiences. 

Kotlin

JetBrains' Kotlin is a statically typed, general-purpose programming language that has inspired world-class IDEs such as IntelliJ IDEA, PhpStorm, App code, and others. JetBrains first introduced it in 2011 as a new language for the JVM. Builders are available in Kotlin for Groovy fans; in fact, Kotlin builders can be type checked. Delegated properties are supported in Kotlin and can be used to implement lazy properties, observable properties, vetoable properties, and mapped properties. Allowing top-level functions is only the beginning of Kotlin's functional programming story. It also supports higher-order functions, anonymous functions, lambdas, inline functions, closures, tail recursion, and generics. In other words, Kotlin has all of the characteristics and benefits of a functional language. Consider the functional Kotlin idioms listed below.

Ionic Framework

An open-source mobile toolkit for creating high-quality native and web app experiences across multiple platforms. Move more quickly with a single code base that runs everywhere with JavaScript and the Web. Ionic is not a new player in the mobile app development market. Ionic was founded in 2013 as an open-source SDK for hybrid mobile applications, and it is now used to build over 5 million apps. It is well-known for providing platformspecific user interface elements through a library of native iOS and Android components. Ionic is essentially an npm module that requires Node.js to function as part of a large JavaScript ecosystem. The UI components of Ionic look great on all mobile devices and platforms. Ionic allows developers to ship apps to app stores as well as PWAs from a single code base. Apps that use Adaptive Styling look and feel at home on any platform.
