I have the same issue. Thankfully, I run this <unknown>:0: error: PCH was compiled with module cache path '/var/folders/14/07yvz9pj24s2r70gt87n3k2r0000gn/C/org.llvm.clang.zorn/ModuleCache/2ZDVRZCAEUI7H', but the path is currently '/var/folders/14/07yvz9pj24s2r70gt87n3k2r0000gn/C/org.llvm.clang.Zorn/ModuleCache/2ZDVRZCAEUI7H'

I'm not sure if it is relevant, and I'm not totally sure how to test it really, but I also see this error message:
My only suspicion is that I am running the latest MacOS on a legacy Mac, via OpenCore which I think has implications on the strictness of SIP. Maybe that is part of the reason? |

Did some testing on my end and it seems that something probably changed in Sequoia with the Driver file (everything save the first import Foundation
struct SwiftErr: TextOutputStream {
public static var stream = SwiftErr()
mutating func write(_ string: String) {
fputs(string, stderr)
}
}
print(CommandLine.arguments)
var dataLocationURL = URL(fileURLWithPath: CommandLine.arguments[1])
do {
let isDataLocationURLReachable = try dataLocationURL.checkResourceIsReachable()
} catch {
print(error.localizedDescription, to: &SwiftErr.stream)
exit(1)
}
Seems to me that changing I have a normal Monterey installation that I can try stuff on if necessary. |

Same problem for me, brand new sequoia 15.1 reinstall on an elegible intel macbook air.
After switching xcode-select to Xcode 16.1.0 (installed via xcodes), both the warning and the subsequent swift check error are solved. |

This warning appears in a brand new Mac mini. The details are as follows:

Most cases of this issue can be attributed to some sort of flawed patch in OCLP for Sequoia. I've updated two machines now (MacMini6,1 and MBP6,1) from Sonoma to Sequoia. Checked before upgrading 2nd machine, saw no issues on Sonoma but immediately saw this issue after installation of 15.1.1 Easiest test case is this:
If dev tools/Swift functions correctly, everything in that array up to the "--" gets stripped out, leaving just Have asked friends and colleagues to check on non-OCLP machines (both Intel and AS); no issues reported. CLT only has been used to provide the demonstrated output above, but the issue also arises if only Xcode is installed (paths are obviously slightly different). Would report to OCLP devs, but don't have Reddit anymore, can't get Discord and Github is still closed (thanks to Putler). FTR the "App Management" change might fix a similar problem, but I've just enabled it before writing this; no dice. |

Output of
brew config
Output of
brew doctor
Description of issue
The command
brew doctor
says:I haven't been able to find any relevant information on how to resolve this issue (Google returns like 5 irrelevant results). Because I need an empty output of the doctor command to create a new issue in the Brew repository, it's blocking me from creating new issues. And I just need to create one.
Is anyone able to help me with this issue, please?
