Simulator Slow-Motion Animations Are Now On

Simulator slow-motion animations are now on?

The shortcut as of Xcode 6 is Command ⌘+T. This toggles it between on and off, so to turn it off just punch that combination.

Slow motion animations with Xcode 5 iOS simulator

It would appear that you toggle slow-motion animations with +T or selecting "Toggle Slow Animations in Frontmost App" from the simulator's "Debug" menu.

ios simulator -- disable slow animations FOREVER?

EDIT: Beginning with Xcode 5.0.1 with the iOS 7.0.3 simulator, cmd+T is now declared as the keyboard shortcut for Toggling Slow Animations and eliminates the observed informal shortcuts listed my my original answer.


This is something that I too encounter all...the...time, but I finally figured out what I was doing to cause it to be enabled in my simulator.

It turns out that iOS Simulator has a few shortcut key for enabling/disabling slow animations that are easily triggered when navigating through simulator (like gaining access to the multitasking bar) or when using system shortcuts for screen shots. I've run across two undocumented keyboard shortcuts:

  • Double-press of CMD+Shift (easy to inadvertently do when gaining access to the multitasking bar)
    • Alternate: Shift + Double-press of CMD
  • Triple-press of Shift

Regardless of the method, if you have a debugger session running in Xcode, you can easily see the console message logging when these shortcuts have activated/deactivated slow-motion mode.

Unfortunately, there does not appear to be a way to disable these 'features' of iOS Simulator. All I've been able to do so far is alter my workflow slightly to avoid key combinations that could trigger slow motion animation, but now have a quicker way to undo the behavior.

Xcode Simulator animations extremely slow when played in editor

If you press command+T it triggers the 'Slow animations' feature. I didn't noticed this setting until now. Doh!

How do I turn off slow motion in the iPhone simulator?

Pre beta 5 it was tripple shift. Apple changed (or broke it) see this question (which doesn't have an answer).

All Animation are executing slowly

This is just a minor problem. I think You have just checked the Slow Animation in simulator by mistake.
All you have to do is that Go to your simulator>Debug>Slow Animation

Uncheck Slow Animation

iOS Simulator does not slow down CA animations

Unfortunately, the Simulator can only toggle the speed of UIView animations.

As a workaround, simply set the speed property of the UIWindow or an arbitrary root view:

view.layer.speed = 0.1f; // 10x slower animations

This slows down all CAAnimations within the layer's sub-hierarchy, including UIView animations.
