Would it be possible to work with thousands of physical bodies in SpriteKit?

I'm new to iOS. What would be the right toolkit to create something like a swarm animation with thousands of objects on the screen moving at high speed?
I noticed that .navigationTitle() behaves differently in iOS and macOS. But couldn't find a reference to this anywhere. On iOS I have to put it on the NavigationViews content but on macOS I have to put it directly on NavigationView for it to show up. I suppose I can make the code platform dependent but it is rather ugly. Am I doing something wrong? Has anyone else come across this?
