I got it working by passing source kit server arguments: i.e: "sourcekit-lsp.serverArguments": [ "-Xswiftc", "-sdk", "-Xswiftc", "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk", "-Xswiftc", "-target", "-Xswiftc", "arm64-apple-ios13.0-simulator", "-Xcc", "-DSWIFT_PACKAGE=0" // Build package as if it were Application? ]
