Introduction
Kotlin is a programming language introduced by
JetBrains, the official designer of the most
intelligent Java IDE, named Intellij IDEA. This
is a strongly statically typed language that runs
on JVM. At Google I/O 2019, we announced that
Android development will be increasingly
Kotlin-first, and weve stood by that
commitment. Kotlin is an open source programming
language that combines object-oriented
programming and functional features into a unique
platform.

Whats new in Kotlin 1.8.0

• New experimental functions for JVM recursively
  copy or delete directory content
• Improved kotlin-reflect performance
• New -Xdebug compiler option for better debugging
  experience
• kotlin-stdlib-jdk7 and kotlin-stdlib-jdk8 merged
  into kotlin-stdlib
• Improved Objective-C/Swift interoperability
• Kotlin Multiplatform
• Compatibility with Gradle 7.3

5
Kotlin/Native

• Kotlin 1.8.0 includes changes to Objective-C and
  Swift interoperability, support for Xcode 14.1,
  and improvements to the CocoaPods Gradle plugin
• Support for Xcode 14.1
• Improved Objective-C/Swift interoperability
• Dynamic frameworks by default in the CocoaPods
  Gradle plugin

Kotlin Multiplatform
Kotlin Multiplatform is in Beta. It is almost
stable, but migration steps may be required in
the future. Well do our best to minimize any
changes you have to make.
7
Android and iOS applications
Sharing code between mobile platforms is one of
the major Kotlin Multiplatform use cases. With
Kotlin Multiplatform Mobile, you can build
cross-platform mobile applications and share
common code between Android and iOS, such as
business logic, connectivity, and more. Check out
the Get started with Kotlin Multiplatform Mobile
and Create a multiplatform app using Ktor and
SQLDelight tutorials, where you will create
applications for Android and iOS that include a
module with shared code for both platforms.

How Kotlin Multiplatform works
9
Code sharing between platforms

• Share code among all platforms used in your
  project. Use it for sharing the common business
  logic that applies to all platforms.
• Share code among some platforms included in your
  project but not all. Do this when you can reuse
  much of the code in similar platforms

10
Few Things Make Easy to Use Kotlin/Native

• Jetpack Componse
• Kotlin Coroutines
• Asynchronous Flow
• App Architecture
• Material Design
• Android KTX
• Safer code

11
Support for Xcode 14.1

• The Kotlin/Native compiler now supports the
  latest stable Xcode version, 14.1. The
  compatibility improvements include the following
  changes
• Theres a new watchosDeviceArm64 preset for the
  watchOS target that supports Apple watchOS on
  ARM64 platforms.
• The Kotlin CocoaPods Gradle plugin no longer has
  bitcode embedding for Apple frameworks by
  default.
• Platform libraries were updated to reflect the
  changes to Objective-C frameworks for Apple
  targets.

12
Kotlin/JS

• Kotlin 1.8.0 stabilizes the JS IR compiler
  backend and brings new features to
  JavaScript-related Gradle build scripts
• Stable JS IR compiler backend
• New settings for reporting that yarn.lock has
  been updated
• Add test targets for browsers via Gradle
  properties
• New approach to adding CSS support to your project

13

• Compatibility guide for Kotlin 1.8.0

Kotlin 1.8.0 is a feature release and can,
therefore, bring changes that are incompatible
with your code written for earlier versions of
the language. Find the detailed list of these
changes in the Compatibility guide for Kotlin
1.8.0.
