$TOOLCHAIN_DIR value missing in Xcode 26 B3

[stefanfessler]

Hey, everyone

when using $TOOLCHAIN_DIR in e.g. the value seems empty/wrong with CLI Xcode 26 B3 selected.
If Xcode 16.4 is selected for CLI everything is ok.
When never installed swiftly also Xcode 26 B3 is ok.

Seems like $TOOLCHAIN_DIR get's messed up from swiftly in Xcode 26 B.
When I change this for e.g. SWIFT_INCLUDE_PATHS

$(TOOLCHAIN_DIR)/usr/lib/swift/pm/ManifestAPI
to
/Users/xxx/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/lib/swift/pm/ManifestAPI
everything is working again.

Thx Stefan
PS: what's the best way to uninstall swiftly?
