Hello!

Last month I bought a new MacBook Pro 13" (early 2015, Core i5 2.7 GHz, 8 Gb RAM, 256 Gb SSD). After clean installation of Xcode 7.3.1 I get simulator that is working slowly. I can see it even in built-in applications like Calendar or Settings. When I'm trying to scroll lists in these applications, they freeze and scroll jerky.

I've tried to toggle on/off "slow animation" mode, but it has no effect.

Have anybody this problem? Or may be my MacBook Pro is not enough powerfull for iOS developing?

Your system should be quite suitable for development. Do you have many other processes running at the same time? What device are you simulating? All rendering is in software, so larger devices (eg: the iPad Pro) are more taxing because of the sheer number of pixels involved.

I suggest you take a sysdiagnose when experiencing the issue and take a look at it to see what might be going on in other processes.
