(Swift) `class func foo()` not highlighted properly

[fel1x-developer]

Describe the issue

In Swift

class func foo()

works like

static func foo()

But highlight.js interpret func as the class name in this case. Both class and func should be interpreted as keywords.

For example,

class func foo() async throws -> [Bar]

becomes

<span class="hljs-keyword">class</span>
<span class="hljs-title class_">func</span>
 foo() 
<span class="hljs-keyword">async</span>
<span class="hljs-keyword">throws</span>
 -&gt; [
<span class="hljs-type">Bar</span>

Whereas,

static func foo() async throws -> [Bar]

becomes

<span class="hljs-keyword">static</span>
<span class="hljs-keyword">func</span>
<span class="hljs-title function_">foo</span>
() 
<span class="hljs-keyword">async</span>
<span class="hljs-keyword">throws</span>
 -&gt; [
<span class="hljs-type">Bar</span>

Which language seems to have the issue?

Swift, manually selected and tested on highlight.js demo page

Are you using highlight or highlightAuto?

I believe when the language is set to Swift on the demo page it uses highlight.

Sample Code to Reproduce

class func foo() async throws -> [Bar]

Expected behavior

<span class="hljs-keyword">class</span>
<span class="hljs-keyword">func</span>
<span class="hljs-title function_">foo</span>
() 
<span class="hljs-keyword">async</span>
<span class="hljs-keyword">throws</span>
 -&gt; [
<span class="hljs-type">Bar</span>
