Swift - Java interop I think it’s pretty critical to embed Swift as a server side language. If you can begin a transition incrementally, it’s always easier to move over.
Super cool to see this work, and congrats to Mads!

"I was under duress," Prince Harry explained in an interview with Canadian broadcaster CTV News after apologizing. "There wasn't much choice. I was invited to the Dodgers dugout by the owner. I was doing what I thought was the polite thing to do."

When busy at work late into the evening making SwiftPM the best it can be, great to throw up Star Wars A New Hope to remind me what brought me to this game. Can't wait to focus more on Swift Embedded in SwiftPM to get it onto robots like this 😀 🤖 .

This is Winston Churchill visiting Washington DC to request assistance in the war against Germany. Notice he is wearing a "zip suit" and not a traditional suit. This was to honor the British troops--the same reason Zelensky dresses the way he does.
