SDAC 9.1 - iOS affected only -TMSConnection: Receiving 'Function is not linked' when connecting

Post by WestyOz » Wed 04 Dec 2019 02:34

Only observed since upgrading the SDAC to 9.1. Only affecting iOS builds.

I am receiving a 'Function is not linked' message when trying to connect. Subsequent attempts at connecting return a 'The certificate is not trusted by the trust provider'. Prior versions of the application built on older SDAC builds function fine. There doesn't appear to be any way of making this work.

Endpoint is an Azure SQL instance. Target platform is iOS 13.2.3.

Specifics with the connection are
TMSConnection.Options.Encrypt := true;
TMSConnection.Options.TrustServerCertificate := false;
TMSConnection.Options.IPVersion := TIPVersion.ivIPBoth;

This error is not occurring with the same application when deployed to Android clients, both 32bit & 64bit.

Is there a known issue?

Thank you for the information.
We have fixed the issue, and the fix will be included in the next SDAC build.
