Slowness in the simulator with Xcode 8


Since I upgraded to Xcode 8, I am experiencing a lot of slowness in the simulator, specifically when entering text in a Text Field, it takes several seconds for the typed letters to appear. With version 7.3, it was perfect. Does anyone else pass it?

When updating to XCode 8 you can experience a slowness since it requires more resources than previous versions, I have experienced the same when I use the Interface Builder.

In fact, if you check the requirements, the same macOS El Capitan requires more resources than its predecessors:


Xcode 8 requires Mac running macOS El Capitan version 10.11.4 or   later It includes SDKs for iOS 10.0, watchOS 3.0, macOS Sierra   version 10.12, and tvOS 10.0.

If you use an HD I recommend changing it for an SSD ...

I had a similar problem but it was more general, placing buttons, WebViews, TextFields, even Labels, but I only changed the hard disk HD 500gb for an SSD, sacrificed 250 gb, but it's worth it, when I started the simulator it took more time 1 minute, this in case your mac is using an HD, otherwise it is rare that you get those problems,
