Same problem for me Domain: DataGatheringNSURLSessionDelegate Code: 1 User Info: { DVTErrorCreationDateKey = "2023-09-19 14:56:45 +0000"; } -- System Information macOS Version 13.5.2 (Build 22G91) Xcode 15.0 (22265) (Build 15A240d) Timestamp: 2023-09-19T18:56:45+04:00

@eskimo, All info in Subject Name section of two WWDR: Apple Worldwide Developer Relations Certification Authority Expires: Wednesday, 20 February 2030 Common Name Apple Worldwide Developer Relations Certification Authority Organisational Unit G3 Organisation Apple Inc. Other Name US Apple Worldwide Developer Relations Certification Authority Expires: Wednesday, 8 February 2023 Other Name US Organisation Apple Inc. Organisational Unit Apple Worldwide Developer Relations Common Name Apple Worldwide Developer Relations Certification Authority Also Issuer Name: for Apple Development: UUU Common Name Apple Worldwide Developer Relations Certification Authority Organisational Unit G3 Organisation Apple Inc. Other Name US So for the first certificate it's Organisational Unit G3 for second it's Organisational Unit Apple Worldwide Developer Relations. My developer certificate based on Organisational Unit G3. But in my case it's working with these 2 certificate in Keychain. For me сodesign fixes itself for a while after any Keychain modification (e.g. I add any new generated certificate in Keychain). So i don't know how it's connected to the issue.

Same here codesign -s "Apple Development: UUU" -f -vvv MyTrue MyTrue: replacing existing signature Warning: unable to build chain to self-signed root for signer "Apple Development: UUU" MyTrue: errSecInternalComponent % security verify-cert -c "Apple Development- UUU.cer" -p codeSign -vvv ...certificate verification successful. --- Certificate chain 0: Apple Development: UUU <cert(0x13f016400) s: Apple Development: UUU i: Apple Worldwide Developer Relations Certification Authority> 1: Apple Worldwide Developer Relations Certification Authority <cert(0x13f016e00) s: Apple Worldwide Developer Relations Certification Authority i: Apple Root CA> 2: Apple Root CA <cert(0x13f017600) s: Apple Root CA i: Apple Root CA> --- Certificate chain properties ( { error = "No error."; title = "Apple Development: UUU"; }, { title = "Apple Worldwide Developer Relations Certification Authority"; }, { title = "Apple Root CA"; } ) --- Trust evaluation results { TrustEvaluationDate = "2022-12-15 17:41:28 +0000"; TrustResultDetails = ( { }, { }, { } ); TrustResultValue = 4; } After I add/remove any certificate in Keychain it signs normal MyTrue: replacing existing signature MyTrue: signed Mach-O universal (x86_64 arm64e) [MyTrue]

Yes, the problem is not with Xcode. Codesign tool also fails. If you look in Keychain, it shows that Apple Development certificate is not trusted. If I touch something in keychain, for example, add/remove any certificate, it becomes Trusted. Apparently there is something wrong with the MacOS 13.0 system.

Same here. An error occurred while loading this image. After 5-10 attempts to upload the same image it finally verifies without error. Spent 1 hour to upload 96 screenshots.
