Building a project with developemnt toolchain fails on M1

Development Source Tooling

Didn't found the right place to ask. I'm trying to build a project with a development toolchain on M1 MacAir. Is this a knowing issue?

xcrun --toolchain "Swift Development Snapshot" --run swift build
/Users/username/Projects/Test: error: manifest parse error(s):
/Users/username/Projects/Test/Package.swift:4:8: error: module 'PackageDescription' was created for incompatible target x86_64-apple-macosx10.15: /var/folders/91/9_b_gpss1t98xcyy6xyg7kdr0000gn/C/clang/ModuleCache/PackageDescription-3KG9PCVIYEOUP.swiftmodule
import PackageDescription
