Just because your car is brand new, doesn't mean the paint is in great shape. Keep in mind your car may have been outside on the dealer's lot for weeks or longer in the elements (wet every day from dew then contaminants baked into the paint by the sun) unless you ordered it and picked it up right when it arrived. I'll admit I'm new to BMW and maybe they take better care of their cars before they deliver it to their customers than other car brands? I bought a three year old CPO (Deep Sea Blue) and I spent about eight hours detailing (wash, clay, polish, seal), getting the paint up to snuff. I even had to clay the windows because they had contaminants embedded in the surface!
My parents just bought a brand new car (Hyundai Azera) and the paint finish was gritty and had a lot of water spots so I had to clay, polish, then seal. I wouldn't be surprised if your paint could at least use some light claying. Your paint finish should be as smooth as glass.
The correct washing/drying method is critical to reducing spider-webbing, holograms, and swirls, especially on a black car. Look up "two-bucket" car washing method. There are some good how to videos on YouTube. Like Ian///M said earlier, it's pretty much impossible to totally eliminate swirls on a black car but you can reduce the chances of getting them by washing/drying with the correct method.
Over the past 15 years, I've owned three different black cars and they can take a lot of tender love and care if you want it to look its best. However, there's no color that looks better and is more rewarding than swirl free black car!
