[iOS Developer Tutorial]: Sharing Common Code with Kotlin Multiplatform Mobile (KMM)

This post was originally published on the Touchlab website. You can also find a video recording on Youtube.  Kotlin Multiplatform is a component of Glovo's company-wide data standardization and transformation solution. It's used across four platforms (Android, iOS, web and backend), demonstrating KMP's unique ability to share code across multiple platforms. In this episode of #TouchlabShare, we're joined by Glovo senior Android engineers, Guillermo Mazzola and Zeyad Gasser. We discuss how KMP evolved from a POC exploration to a critical component for how the organization makes data-drive decisions.

Subscribe to the Touchlab newsletter and stay informed on all the latest technical advancements in Kotlin Multiplatform Mobile! We also share strategies for managers planning to innovate their teams' mobile development with KMM. Episode Description JetBrains just released its inaugural Kotlin Multiplatform (KMP) survey. They write, "The Kotlin team has always relied on feedback from the community for making decisions about the future of the technology. You will always be our go-to people who know best how to make Kotlin even more enjoyable to work with! This past November, we conducted our first-ever Kotlin Multiplatform survey with the goal of understanding how the recent changes in the technology have shaped the ways developers use it. This initiative was well received by the community, resulting in an astonishing 1163 replies and 614 fully filled-out surveys, which are the basis for this report. We want to say thank you to everyone who took the time to share their feedback with us. As a result of this survey, we were able to get a much more complete understanding of our users, how the technology is generally used, and what problems need to be solved to help those using Kotlin Multiplatform for work, personal, or university projects and those who are thinking about adopting Kotlin Multiplatform." (Source) We're also releasing something for the first time. It's our latest media segment called #TLTouchPoints. They are shorter format reactions and commentary on the latest developments and updates in the Kotlin Multiplatform Mobile (KMM) community. In this episode, Touchlab Dir. Project Strategy Justin Mancinelli shares reactions and implications from the KMP survey for managers interested in putting KMM into production at their organization.

In this recorded episode of #TouchlabShare, we ask Touchlab mobile engineer Russell Wolf about his KMM open-source library, Multiplatform Settings.  He goes over the impact the library has had on his career, how he incorporates feedback from consumers to guide the project’s roadmap and code and API design decisions he’s made along the way.   The story of how he decided to develop an open-source project for Kotlin Multiplatform is a great one! It started with a call to action by Kevin Galligan in which he said the KMM community needed developers to build libraries. Russell took Kevin up on his challenge and the library, Multiplatform Settings was born.  You can watch the recorded video segment on YouTube. 

In this episode of #TouchlabShare we invited a member of the KMM community, Ahmed El-Helw (LeadAndroid Engineer @ Careem) from Dubai. We discuss his latest exploration of multithreading and his experience being one of the earlier engineering leaders to put KMM into production.

Touchlab Kotlin Multiplatform Mobile (KMM) and iOS engineer Ben Whitley developed a getting started fast with KMM tutorial for iOS developers. In this recording of an earlier #TouchlabShare live session, Ben walks a live audience through the tutorial, share tips on how to convince your iOS developers to pilot KMM and then opens it up for questions from the audience.  You can register to immediately receive the KMM getting started tutorial for iOS engineers on the Touchlab website.  You can also access video of this session on Youtube. 

Identifying candidates for common code sharing can be difficult. In this recorded session of Touchlab Share, engineering manager Sam Hill discusses common places we recommend clients start common code sharing with Kotlin Multiplatform. We also field questions from the audience. If you're interested in starting small with KMM (and with minimal risk), please register to receive KaMP Kit, a collection of code and tools to get you started fast with KMM. 

Touchlab Director of Project Strategy Justin Mancinelli walks listeners through a framework we developed for evaluating multiplatform solutions. A video recording of the live webinar can be be found here.
