Code Generation Using Kotlin Symbol Processing (KSP)
summary
Kotlin Symbol Processing (KSP) is presented as a faster alternative to KAPT by parsing Kotlin natively; the talk shows a concrete example that builds a Processor module and a consumer module using SymbolProcessorProvider and a SymbolProcessor that calls Resolver and codeGenerator.newFile to emit code. It covers multi-round processing by deferring symbols via validate = false and explains how to enable incremental builds by declaring inputs and outputs. It notes that Room already supports KSP but many major libraries do not, so additional migration work is needed for production use.
