Isn't it... Just in xcode? I've used it. It's like, there, right?
I open up my 13.3 beta 2 and go to the xcode tab go down to open developer tool click on simulator and then click on file and then open simulator my mouse over to iOS 15.4 go down to the iPhone 13 for example click on it and then I have a simulated iPhone 13...
And if I check the activity monitor nothing in my activity monitor is showing up as Intel code except for parsec right now...
