I’m currently refactoring some code (Swift 3.?, latest XCode), and I ended up
with the following:
func spansTSON() -> TSON {
var docs = self.spans.map() { $0.tson }
for (span, doc) in zip(self.spans, docs) {
if let datum = span.begin.datum {
if let index = self.spans.index(where: {return
$0.includesAnchor(datum)}) {
doc["datum"] = (index * 2 +
(datum.isBegin ? 0 : 1)).tson
}
}
}
return TSON.array(docs)
}
The vague error I get is “Ambiguous reference to spans” on the “if let index =
self.spans…” line with the “self” highlighted. The container is a class.
“spans” is computed property. I’m not sure if it’s confused about what self is,
or spans. Or why either wouldn’t be clear.
