I'm writing an LDAP Browser app using SwiftUI. I tested my LDAP code using a command line app that uses the exact same libraries and it successfully connects to my LDAP server over a TLS connection. I did need to install the CA cert into the system keychain. The SwiftUI version, using the exact same code and parameters returns an "Unknown CA" error. It works fine without TLS. Can anyone explain why certificate validation is different for a GUI app?

I'm writing a SwiftUI LDAP Browser. I built a command line swift app to do some testing and it works fine. I had to add the certificates from the LDAP server to the system keychain before it would work with TLS/SSL. Then I ported the same code into a SwiftUI app but I cannot get it to connect via TLS/SSL. On the same machine with the same certs it errors with: An unexpected error occurred: message("Can't contact LDAP server") It connect fine with our TLS/SSL. I suspect this may have to do with App Transport Security. Can anyone point me in the right direction to resolve this? App is MacOS only.
