Hi Quinn! Here is the curl call and the response: https://xxx.yyy.com/bep/recovery/v2/accountStatus/abcd?OSVersion=ios_17.5&brandName=BRANDNAME&channelId=&clientAppName=com.company.company-native-myaccount&clientAppType=FULL&clientAppVersion=24.02.2025&deviceId=&deviceModel=iPhone&language=ENG&sourceSystem=APP&subBrandName=BRANDNAME Host xxx.yyy.com:443 was resolved. * IPv6: (none) * IPv4: x.x.x.x * Trying x.x.x.x:443... * ALPN: curl offers h2,http/1.1 * TLSv1.3 (OUT), TLS handshake, Client hello (1): * Recv failure: Connection reset by peer * TLS connect error: error:00000000:lib(0)::reason(0) * OpenSSL SSL_connect: Connection reset by peer in connection to xxx.yyy.com:443 * closing connection #0 curl: (35) Recv failure: Connection reset by peer This is using Palo Alto Global connect in the US, offshore engineers using Cisco VPN do not see this with the same apps running on the simulator. Sorry I had to obfuscate some info, but I think you will understand. This all seems to be most closely correlated with the macOS 15.6.1 update.

What iOS SDK version are you targeting?

The problem was that Apple renamed the environmental variable "DT_TOOLCHAIN_DIR" to "TOOLCHAIN_DIR" without any notice as far as I can tell. This broke pod install for CocoaPods when running version 1.12.0. The CocoaPod group fixed this with the latest 1.13.0 version. The only thing you should be aware of is that you have to be using Xcode 15. Xcode 14 still uses DT_TOOLCHAIN_DIR so to be compatible with CocoaPods you must use v1.12.0 with Xcode 14.3.1.

Anyone here? Why has this not been addressed publicly by Apple? This is a key piece of functionality to develop and understand CoreData models. Some input from Apple would be helpful here lest everyone moves to Realm.
