in 2008 when the first version of Apple's App Store was released, users would only find 500 apps there. A decade later, Apple CEO Tim Cook announced that there were 20 million registered iOS developers who made about $ 100 billion in revenue while serving about 500 million weekly visitors to the App Store.

Impressive isn't it? Well, in 2020 these figures will surely be even higher. Along with Android, iOS will continue to be a leading mobile development platform.

The Future of iOS App Development: iOS Development Trends for 2020

One of the key user interface trends in 2020 will be SwiftUI, a suite of user interface tools that allows developers to declaratively design applications. All that is needed is to simply tell SwiftUI how we want our user interface to look and work, and the tool will figure out how to make that happen when the user interacts with it.

To understand what declarative UI is all about, let's compare it to imperative UI. Before iOS 13, developers used only an imperative user interface. In imperative UI, a function can be called when a user clicks the button. Inside that function, ...
... we read a value and display a label. We can modify the appearance and operation of the user interface based on what happens on a regular basis.

But imperative UI raises many problems, particularly those related to the concept of state. Developers need to track the state their code is in, and then ensure that the UI reflects that state correctly.

Is that how it works

Event streams are streams of values ​​that we can operate on. By using the operators included in a reactive framework, developers can easily transform one sequence into a different sequence in situ.

Reactive programming is no stranger to the iOS platform. Developers could use various libraries for that purpose. The reactive pattern in iOS allowed developers to start thinking about how events work and how they depend on each other, as well as how everything affects business logic.

Here's how it works according to Apple's developer documentation

“Combine declares that publishers expose values ​​that can change over time and that subscribers receive those values ​​from publishers.

The Publisher protocol declares a type that can deliver a sequence of values ​​over time. Publishers have operators to act on the values ​​received from previous publishers and republish them.

At the end of a publisher chain, a subscriber acts on items as they are received. Publishers only issue values ​​when subscribers explicitly request it. This allows your subscriber code to control how quickly you receive events from publishers you are connected to.

Flutter offers a new and more productive way to build mobile apps by combining the benefits of a native framework with cross-platform.

Future of iOS development and trends for 2020 - overview

This year, we will see many iOS development

trends solidify their presence on the mobile development scene.

Flutter will only get bigger and developers will take advantage of new tools to create ios and AR applications. However, I am sure that the new iOS app development trends are just around the corner, and we will see some of them this year.
