Come join us for our monthly iOS and Mac meeting.

This Month’s Presentation:

“To Cross platforms, or to not cross platforms, that is the question”

For nearly the entire history of GUI development, there have been efforts to write once, run everywhere. Oftentimes this means performance problems, appearance problems, tool complexity, and challenges debugging–all for the sake of saving a lot of development time. How do today’s cross platform solutions stack up?

In this session we will explore Xamarin, React Native, Flutter, and Kotlin Multiplatform. How do you install these tools? How good does your app end up looking? How hard is it to support? Is the framework just for mobile or is it for all types of apps? Once we have the tools installed, we will attempt to build a simple calculator app on each platform and evaluate the results.

Mike Kennedy, long time Columbus resident, attended OSU in EE, worked at NCR, CompuServe, Hublink, Foresight and TIBCO. Always interested in new tools and programming languages. Have three grown kids and recently became a grandpa. Also very interested in music and play piano, tuba, and bass.
