Exactly. A Non-EU especially needs both permit and passport when leaving Switzerland.

The Schengen Agreement has an impact on the movement of persons. Holders of the following Swiss residence permits may travel within the Schengen Area* without a visa for stays of up to 90 days:

B permit (residence permit)
C permit (settlement permit)
L permit (short-term stay permit)
Ci permit (residence and work permit)
Diplomatic ID cards issued by the Federal Department of Foreign Affairs (FDFA)

You must bring your Swiss permit and a valid travel document with you when travelling.

No, you cannot.

I boarded once a plane on expired ID (of destination country) and returned on expired Swiss ID to Switzerland.

Other way around wouldn't be possible

I had no idea these things have expiration data. You won't lose citizenship after 10-years being outside of the country - even so one may wish when watching IRS bills ...

Actually Switzerland explicitly accepts expired travel documents (even of other countries) in certain cases. There's a whole FAQ on the topic of valid travel documents (for Switzerland) here:

I managed to travel from Brussels or Luxembourg to Switzerland using a drivers licence. This was in Schengen times to prove my ID against my ticket.

If I had a library card, I would have tried that at the time

My gf once tried to board a plane using just and ID card and the lady at the gate wouldn't have any of it. She said she needed a passport. My gf said no, she is wrong and she travelled using the id card many times and started to get angry. After a few minutes of fruitless attempts at persuasion she was handed her ID back at which point she noticed that she'd handed over her gym membership card by accident

I've literally done it dozens of times coming and going back/from Spain.

M’y husband did that all the time when he was doing the weekly commute between Brussels and Geneva and never had an issue.
This was pre-brexit days obviously.

Then you were breaking Spanish law at least, which requires you to carry a government issued identity document. The residence permit is NOT an identity document.

Of course the average Spanish police probably don't know that, and probably don't really care as long as it looks official enough.

Whether you have done it or not is totally irrelevant, the fact is that a residence permit is not a valid identity document and legally you are required to have one of those for travel.
A Swiss permit is not a valid identity document even within Switzerland but is often accepted as such.

Right, so you are telling us that you were allowed to board planes in Zürich and Spain without an acceptable identity document and that you have been checked by the authorities and they accepted it, is that what you are saying?

Or have you just traveled around the Schengen Area unrestricted like everyone else?

Hi all,

My new UK passport arrived today

So the process from the start on 16 May to delivery 7 June only took 3 weeks. Very efficient service!

In case your wondering the application was an adult renewal and I uploaded a digital photo I took on my phone.
