The idea that women or girls being uninterested in getting jobs in engineering due to masoganistic workplaces or hiring practices is putting the cart 10 years ahead of the horse.
I think it was a combination of older people getting stuck in their ways and not easily learning new thing - along with the massive complexity in newer OSX - along with a little nine-headedness - like no right mouse button, but a billion was of needing that functionality and other less-than-obvious ways of accessing it (like pressing on the right SIDE of the Magic Mouse, etc)
Swift aimed to clean up some of the cruft from Objective-C and has somewhat fallen into all the same traps. It had inherently avoided all the C and C++ compatibility issues - yet is still one of the 2 ways of doing a native iOS app.
So it's maybe, arguably, marginally *easier* than Objective-C, yet is one of two technologies to allow you to code inside Apple's walled garden - so, people are using it - but it's like praising a Siberian prison for serving thicker soup on Tuesdays.
(BTW - we did make the black candidate and offer - he accepted, then shot us down after getting a counteroffer from his employer to stay. )
Take an astronaut to launch.
