I am trying to generate an XML document using Swift on Linux. But the following code doesn't compile:

let rootElement = XMLElement(name: "feed")
rootElement.setAttributesWith(["xmlns": ";])

I get the error 'XMLElement' (aka 'AnyObject') cannot be constructed because it has no accessible initializers. I am surprised since XMLElement is part of Foundation, which works on Linux, right? Is there something I am missing?

• swift
• foundation

• XMLElement is only for macOS according to the documentation. While the Apple docs never mention Linux, just because a class is in Foundation for one particular platform does not mean it is available for other platforms. – HangarRash Commented yesterday
• Since the docs never mention Linux, how are you supposed to know if something works on Linux or not? – Kevin Renskers Commented yesterday

The fix is to add the following guarded import to the file:

#if canImport(FoundationXML)
import FoundationXML
#endif
