this problem isn’t new to me, but i’ve recently become more conscious of it now that i’ve started doing work in places that have “normal” internet connections, like my neighborhood Starbucks.
fetching dependencies with SPM takes a really long time, and it seems to disproportionately affect Apple packages like swift-collections.

some of these packages, like swift-syntax are quite large and i am not surprised that they take a very long time to download. but others like swift-collections are tiny (in terms of source code footprint) and still take 21s to download. the only explanation i can think of is that SPM is fetching the entire repo history, because it should not take 21s to download the source code of a package like swift-collections.
is there anything that can be done about this?
