I'll bet it runs very very slow. I used to run it on a Mac Mini with 4GB RAM and that's how it performed - very slow but acceptable. I just switched over to a MacBook Pro with 16GB of RAM and the difference is stunning! Anyway, I don't think you will have any problems as such. Just poor performance running the simulator.hi..
Does xcode simulator cause problems in macbookAir(2014) 4 gb ram ?
