We are examining SWIFT for engineering applications.
Can you tell me if SWIFT has graphics/Plotting libraries? If so, please send a link so we can evaluate the capabilities.

Engineering software is also my area. Welcome to the Swift forum 
. I am not particularly familiar with the Cocoa graph plotting libraries. One of the things that makes me really excited about Swift is the seamless Python interoperability meaning that I can make an app that leverages the full power of established libraries such as matplotlib. See Chris Lattner discussing this feature here Swift for TensorFlow: The Next-Generation Machine Learning Framework (TF Dev Summit '19) - YouTube.
