Slow app performance under iOS 8 simulator with Xcode 6

After upgraded to xcode 6 I found that when I run my app under iOS 8 in iOS simulator, it ran very slowly, no matter when I choose iPhone or iPad. But if I choose it to run under iOS 7 it ran normally. I was thinking that it was an app/coding related problem so then I tried to deploy it on my ipad with iOS8 and strangely the app run normally, not as slow as simulator does Does anybody on SO experience this issue?

Why is IOS simulator slow?

You accidentally pressed the slow animation on debug when using simulator. So Run Simulator -> Debug -> Uncheck Slow Animation.

Do I need Xcode for IOS simulator?

Launching the Simulator, though, always requires opening Xcode and going to Developer Tools. Because the Simulator. app is embedded within the Xcode app bundle, apps like LaunchBar won't find it to index it. LaunchBar, which is my launcher of choice, also ignores aliases, so dragging Simulator.

Make sure 'slow animations' is not selected under the Debug tab in the iOS Simulator. That fixed the issue for me. It might have been turned on by accident.

If you hit ⌘T while your simulator is selected it will turn on 'slow animations' which puts everything in slow motion. ⌘T is often used to open up a new browser tab, so just be sure your browser is selected and not your simulator.
