I am having a problem in the "Layouts in Jetpack Compose" Codelab. Chapter 6 "Create your custom layout". You are supposed to map a List of Measurables to a list of Placeables.

The map operator doesn't work for me though. I am getting the error:

Unresolved reference. None of the following candidates is applicable because of receiver type mismatch: ...

.fastMap works though.

Why is this happening? Should I report this?

I think my sample project is misconfigured. Missing many collection functions. The next chapter uses .maxOrNull and .sumBy on IntArrays but they are also not available

Fixed the problem by upping the kotlin and compose kotlinCompilerVersion version from 1.4.0 to 1.4.10
