Akka has experimental support for Scala 3.
Akka is written in Scala, with language bindings provided for both Scala and Java. Akka's approach to handling concurrency is based on the Actor Model. In an actor-based system, everything is an actor, in much the same way that everything is an object in object-oriented design.
Akka is built with Scala, but offers both Scala and Java APIs to developers. At the heart of Akka is the concept of Actors, which provide an ideal model for thinking about highly concurrent and scalable systems. Writing concurrent systems using traditional low-level mechanism such as locks and threads is difficult.
Scala 3 introduced a bunch of language features like enums, extension methods, new context abstractions, type lambdas and a lot of niceties that make our life easier. The compiler is also different, faster and with backward compatibility between Scala 3 versions. Is Scala 3 production ready? Yes!
akka-actor-typed is published for Scala 2.12, 2.13, not for Scala 3
https://mvnrepository.com/artifact/com.typesafe.akka/akka-actor-typed
Try compatibility mode
lazy val foo = project.in(file("foo"))
.settings(
scalaVersion := "3.0.0",
libraryDependencies +=
("com.typesafe.akka" %% "akka-actor-typed" % "2.6.15")
.cross(CrossVersion.for3Use2_13)
)
