I'm working from a late 2011 13" MBP, and archiving my Xcode project uses 100% of my CPU and my fans start blasting. I need an upgrade. Can someone suggest a 2016 MBP configuration that would be excellent for developing iOS apps? Do I need quad core power? Budget under $3500 CAD (or $2700 USD). I realize any new computer would be a significant upgrade over this one, but suggestions please. thanks.
