For both new and experienced programmers, iOS is generally easier to develop for. iOS apps generally require less development time and are cheaper to build and maintain than Android apps. iOS developers use Swift, Apple’s native programming language, whereas Android developers typically use Java and/or Kotlin.

Which device is better to learn: iOS or Android? 

If you want to target Apple product users, learn iOS development; if you want to target different consumer bases, then consider learning Android.

You need to know Swift to develop for iOS. Swift is a modern programming language designed specifically for Apple products. The code is relatively straightforward and easy-to-read for beginner programmers. However, Swift is unique to Apple products and generally not commonly used outside of iOS app development.

Android products rely on Java and Kotlin. While Kotlin is largely confined to just Android app development, Java is a popular programming language that has been around since 1995. The Java programming language has many use-cases outside of Android products; if you are a programmer who is interested in mobile app development but want to keep your options open, then learning Android app development would be helpful for you.

What is the main difference between developing iOS and Android?

There are some crucial differences between iOS and Android app development:

• iOS app developers use Swift, whereas Android app developers use Java or Kotlin.
• With Apple devices, there are standardized screen sizes for iPhones and iPads. With Android devices, there is a large variety of screen sizes—meaning you need to work more on interface design and case-by-case programming to ensure compatibility and functionality across devices.
• Android apps take longer to develop because of device fragmentation—the fact that there are so many different Android OS versions on the market. Different devices get important security updates at different times, and this makes maintaining and developing Android apps more challenging.
• iOS and Android apps have different user demographics—age, income, hours spent on apps, locations, and so on. Apple users tend to be younger and more affluent than Android users.

When developing apps, consider these differences, analyze your target audience, and ask yourself whether you want to minimize the amount you spend on development time and maintenance.
