We want that the runtime only depends on
FoundationEssentials
where available (ie. on linux) to ensure small binary size.Motivation:
Smaller binary size is good for lambda deployment and cold-start times. The runtime should only depend on
FoundationEssentials
.Modifications:
import Foundation
withimport FoundationEssentials
ifFoundationEssentials
is available.Foundation
which easily happens when you develop on macOS (where always fullFoundation
is available).Result:
This should allow builds without linking full
Foundation
.
