Whitespace removed around standalone macro with attribute

[klanchman]

When a using standalone macro with an attribute on it, swift-format wants to remove whitespace around the macro.

The following example assumes the default swift-format configuration. Tested on 509.0.0 and main.

Input:

@available(iOS 17.0, *)
#Preview("Name") {
  EmptyView()
}

Expected output: same as input

Actual output:

Test.swift:1:24: warning: [RemoveLine] remove line break
Test.swift:2:17: warning: [Spacing] remove 1 space

@available(iOS 17.0, *)#Preview("Name"){
  EmptyView()
}
