Can this use UTIUtilities' UTIFromMIMEType?

Nit - This type should be NSArray<NSString *> *.

"utis" is also a bit of a strange variable name...perhaps "typeIdentifiers" or just "types"?

NSString *

(__bridge CFStringRef)

> +            [mediaTypes addObject:(NSString *)UTI.get()];

(__bridge NSString *)

> Source/WebKit/UIProcess/ios/forms/WKFileUploadPanel.mm:363
> +    NSArray *documentTypes = mediaTypes.count ? mediaTypes : @[@"public.item"];

Nit - This isn't new code, but maybe consider using the kUTTypeItem constant instead of @"public.item"?
