driver embedded in app cannot open connection

[drwo]

Thanks for developing this driver. It will be a big boon to my development efforts if I can get it working, to which see:

I have successfully downloaded and built the driver using Xcode version 9.0.1, High Sierra 10.13.3. All of the tests work fine, I can connect to SQL servers locally and remotely, use databases, etc.

When I embed the driver in a Coca app and attempt to open a connection to "localhost" an exception is thrown that the operation is not permitted:

applicationDidFinishLaunching

connectFailed("Operation not permitted")

applicationWillTerminate

Any ideas or suggestions much appreciated.

Thanks,

Looks like App Sandbox has got in your way.
In your project capabilities you need to select Network: Outgoing connections (Client).
