iPhone Simulator - Black Screen

I successfully run basic iOS applications on my Hackintosh OS X Yosemite 10.10.1. But when i try to run any iOS app using a WebView, the simulator gets very slow, then shows a black screen and quits the app.

My PC overview:

• Processor 2.2 GHz Intel Core 2 Duo
• Memory 2.00 GB 800 MHz DDR2 SDRAM
• Graphics Asus GeForce 8600 GT 512 MB

iPhone is pretty expensive for me. Do i have to look for real one to debug apps fine? Thanks in advance!

For iOS development on Hackintosh u need at least 4Gb RAM.
