getPost(bySlug:from:completion:) endpoint does not return collection alias

[AngeloStavrow]

This isn't exactly a bug — the Write.as/WriteFreely API doesn't return collection information on the GET /api/collections/{COLLECTION_ALIAS}/posts/{SLUG} endpoint (or GET /api/posts/{POST_ID}, for that matter), so technically this method on WFClient follows that behaviour.

It does, however, mean that you get back a WFPost whose collectionAlias property is nil — which is unexpected, given that you asked the API to fetch a post from some specific collection.

And so, I'm categorizing this as a bug: on success, the method should insert the collection alias that it was given back into the WFPost object that is returned to the completion handler.

Workaround: Don't overwrite the post's collection alias in your client's completion handler for this method (or, keep a reference to that collection alias, and re-insert it into your client's post type).
