Ioinic build very slow + xCode build very slow

I guess its an overall performance question: how can I speed up my ionic build and xcode build? It takes around 2-3' for ionic build to complete, and when I build exactly the same code from my friends MacBook its just flies.. The same with xCode building on my real device. Its true, I have Early 2011 MacBook Pro with HDD. Any ideas how can I speed up this process?

Why use X-code to build again and again.

Use "ionic run -l -s -c" while your device is connected, and you'll be able to set up live reload on your device.

(make sure you are connected to same wifi)
