Kotlin At 60fps ⚡️Write Hot Code Without Losing Your Cool

Kotlin has indisputable benefits. It's terse, expressive, and addresses some of Java's oldest issues at the compiler level. For much of the code we write, the runtime performance difference is negligible.

Occasionally, however, a hot code path will reveal the truth about primitive boxing, immutables, capturing lambdas, or delegates. Do we have to abandon Kotlin to write faster code?

In this session we'll discuss:

• Under the Hood: Where hidden performance costs typically appear
• Measure: Find the hitch in your framerate
• Typesafe Tricks: Rewrite it with zero allocations, all in Kotlin

• Development
