Kotlin Native Training Overview
This Kotlin Native training course teaches attendees how to use Kotlin alongside native applications and libraries written in C, C++, Objective-C, and Swift. Students learn how to generate Kotlin library wrappers using headers from these other languages. Participants then learn how to write Kotlin that easily calls into native API’s and how to consume Kotlin Native libraries from other environments. Finally, attendees put it all together to see how everything fits into the wider Kotlin ecosystem by creating multi-platform projects that target the JVM, Android, JS, and Native platforms.
Location and Pricing
This course is taught as a private, live online class for teams of 3 or more. All our courses are hands-on, instructor-led, and tailored to fit your group’s goals and needs. Most Accelebrate classes can be flexibly scheduled for your group, including delivery in half-day segments across a week or set of weeks.
