Depreciated SPM file - how many others?

Using Swift

swift package init --type executable

I use this command on Linux all the time, but today I used it on the iMac, inside a new folder I created on the Desktop, and got this...

The iMac has Monterey 12.3 with Xcode Version 13.3 (13E113) installed.

I'm wondering if a related misconfiguration might explain why Xcode is able to crash a connected Linux system, and corrupt the project's directory, when using it to edit Linux hosted source code.

So I've deleted the depreciated file and the error goes away, but how many other redundant files are lurking around and ready to bite?

Yes I wonder the same thing! I wrote a question on Stack Overflow one month ago when I used Xcode 13.3 beta 3

To my knowledge SwiftPM only writes to three places:

  1. ~/Library/org.swift.swiftpm: configured mirrors, package collection lists, package fingerprints, etc.
  2. ~/Library/Caches/org.swift.swiftpm: global cache of fetched packages
  3. .build in each package directory: products and intermediates of the particular package’s build

All are safe to delete as long as SwiftPM is not running. 1 contains the global configurations, so deleting it essentially reverts to factory defaults. But 2 and 3 are just caches, so you lose nothing if you delete them.
