It's ShowTime! 🎥

ShowTime is the simplest and best way to display all your taps and gestures on screen. Perfect for that demo, presentation or video!

All you need to add that extra polish your demos is to add the Swift package dependency to your app target, you don't even need to import ShowTime if you don't want to change any of the options!

ShowTime can be configured to show the actual number of taps performed. Apple Pencil events are ignored by default but this can be configured.

ShowTime works as soon as your app runs, with no setup required, but is also highly configurable if you don't like the defaults.

ShowTime works with single- and multi-window setups out-the-box, without the need to subclass or set a UIWindow.

Check out How it works.

It takes less than a minute to install ShowTime, consider using it when you're sharing or recording your screen through QuickTime or AirPlay to help give your viewers extra context.

By default, the size of the visual touches are 44pt; this mirrors Apple's guidelines for minimum hit size for buttons on iOS. You're free to change this, of course!

Showing your gestures during demos gives your audience a much clearer context on what's happening on your device. Try ShowTime for your next demo, it's super easy to set up!

ADDED BONUS: Adding ShowTime to your app in debug mode will show taps and gestures in your XCUI automation tests while the tests run!



Swift Package Manager

  • Step 1: In Xcode 11+, add https://github.com/KaneCheshire/ShowTime.git to the list of Swift Package dependencies, see here for more information.
  • Step 2: There is no step 2, ShowTime works as soon as you launch your app, but you can configure it if you wish!


NOTE: I won't be supporting Cocoapods for future updates, but for for now the podspec will remain in the repo with the last released version for Cocoapods. You can always install the latest ShowTime.swift manually if you want newer updates but can't use Swift Package Manager yet.

  • Step 1: Add pod 'ShowTime' to your Podfile and run pod update in Terminal.
  • Step 2: There is no step 2, ShowTime works as soon as you launch your app, but you can configure it if you wish!


  • Step 1: Drop ShowTime.swift into your project or copy the contents of it where ever you like.


ShowTime works out of the box (you don't even need to import ShowTime in any file), but you can customise it to turn it on or off, change the colour of the taps, plus lots more options.

There's lots of options to play with which helps ShowTime work with your app's character and theme during demos.

Here's a list of options:

// Defines when and if ShowTime is enabled.
// Possible values are:
// - .always
// - .never
// - .debugOnly
// `.always` by default,
ShowTime.enabled: ShowTime.Enabled

// The fill (background) color of a visual touch.
// When set to `.auto`, ShowTime automatically uses the stroke color with a 50% alpha.
// This makes it super quick to change ShowTime to fit in better with your brand.
// `.auto` by default.
ShowTime.fillColor: UIColor

// The colour of the stroke (outline) of a visual touch.
// "Twitter blue" by default.
ShowTime.strokeColor: UIColor

// The width (thickness) of the stroke around a visual touch.
// 3pt by default.
ShowTime.strokeWidth: CGFloat

// The size of a visual touch.
// 44x44pt by default.
ShowTime.size: CGSize

// The style of animation  to use when a visual touch disappears.
// Possible values are:
// - .standard (Slightly scaled down and faded out)
// - .scaleDown (Completely scaled down with no fade)
// - .scaleUp (Scaled up and faded out)
// - .custom (Provide your own custom animation block)
// `.standard` by default.
ShowTime.disappearAnimation: ShowTime.Animation

// The delay, in seconds, before the visual touch disappears after a touch ends.
// `0.2` by default.
ShowTime.disappearDelay: TimeInterval

// Whether visual touches should indicate a multiple tap (i.e. show a number 2 for a double tap).
// `false` by default.
ShowTime.shouldShowMultipleTapCount: Bool

// The colour of the text to use when showing multiple tap counts.
// `.black` by default.
ShowTime.multipleTapCountTextColor: UIColor

// The font of the text to use when showing multiple tap counts.
// `.systemFont(ofSize: 17, weight: .bold)` by default.
ShowTime.multipleTapCountTextFont: UIFont

// Whether visual touches should visually show how much force is applied.
// `true` by default (show off that amazing tech!).
ShowTime.shouldShowForce: Bool

// Whether touch events from Apple Pencil are ignored.
// `true` by default.
ShowTime.shouldIgnoreApplePencilEvents: Bool

How it works

ShowTime is a one-size-fits-all solution to showing your taps and gestures while showing off your hard work in demos and videos. ShowTime works with both conventional single-window apps, as well as multi-window apps.

To achieve this, ShowTime uses method swizzling. Method swizzling is only possible with the Objective-C runtime, so will only work with Swift types that inherit from NSObject. That's okay, because UIWindow does inherit from NSObject, so ShowTime can swizzle the sendEvent(_:) method.

Swizzling is just a friendly term used for swapping out the default implementation of a method and replacing it with your own (which calls the default implementation, a bit like calling a super implementation of a class), so that you have more control over what happens with that method without having to subclass. The benefit – but also danger – of this is that all objects instantiated will use the new implementation, so swizzling should be used wisely and sparingly, especially in production code.

ShowTime swizzles the sendEvent(_:) method on UIWindow, intercepts the event and then lets UIWindow carry on with sending the event. By intercepting that event and extracting the UITouches out of it, ShowTime displays those touches visually on whatever window is receiving sendEvent(_:).

Useful info

Why don't I need to import ShowTime to get it to work?

ShowTime automagically swizzles functions which doesn't require the framework to be imported with import ShowTime, it just requires installing the code somewhere in a target (via Swift Package Manager, Cocoapods, or manually copying the code). The only time you'll need to import the framework is if you want to play around with the configuration. If you're wondering how the swizzling happens automatically, ShowTime overrides UIWindow's layer property and performs the initial swizzling setup there. So the first time a UIWindow's layer property is accessed, the swizzle happens automatically.

Can I use this in production?

Yes, I've never seen any weird crashes but it's never been stress tested, so to do so is at your own risk.

Why would I want to show the number of multiple taps?

People watching a demo of your app don't know exactly what your fingers are doing, especially if it's a screen recording or over Zoom, so showing how many times you've tapped on a specific part of the screen really helps people understand the gestures you're carrying out.

Double tapping makes sense if you're watching someone's hands, but often this can be easily missed if you're watching it on a screen. Showing the number of multiple taps by setting ShowTime.shouldShowMultipleTapCount to true shows a number inside the tap itself, clearly demonstrating to your audience that you just tapped twice (or more) in succession in the same place.

Why don't Apple Pencil events show by default?

I'm guessing that most of the time, if you're demoing using an Apple Pencil then you're demoing drawing or something similar, so you wouldn't want a touch to display at that location. You can easily disable this behaviour if you need touch events to show for Apple Pencil interactions.

Can I have a different colour tap per-screen rather than per-app?

This is possible, you'd just need to set the colour in viewDidLoad or viewDidAppear(_:) in the screens you want to change the colour of the taps on. It adds a small layer of complexity, but certainly possible.
