Transaction.disablesAnimations = true controls animation per transaction.
Since iOS 14, there is a SwiftUI’s private .unanimatable() modifier which disables animation for a view subtree at the graph level.

Besides a WWDC session, you can also get a source debuggable experience with OpenSwiftUI to fully understand SwiftUI's amazing client side animation model designed by Kyle Macomber.
For those who are curious about the implementation detail, here is a quick article for a brief understanding. openswiftuiproject.org/blog/…
If you want to learn more about how SwiftUI animation works, and that in fact most of the time its animations run off the main thread, check out: developer.apple.com/videos/p…

Add a feature flags shim layer so that we can query the same result in OpenSwiftUI as we are in SwiftUI domain.
After all, we do not have permission to place one under /System/Library/FeatureFlags/Domain/

TLDR: SWIFTUI_GESTURE_CONTAINER=0 +SWIFTUI_EVENT_DEBUG=G will makes all SwiftUI app on iOS 18.0~iOS 27.0 crash when you tap a text.
While building a SwiftUI gesture GUI debugger, I found that tapping a plain Text can crash the app with gesture containers disabled.
The cause: AttributeGraph reads an array during a mutating call.
Repro, workaround, and OpenSwiftUI fix:

Trust me, no one was more interested in open-sourcing SwiftUI than many of the people working on SwiftUI!
Because selfishly, it would then be a lot more clear to everyone how much of it is *not* a thin wrapper around UIKit and AppKit. It’s a full stack UI framework on its own, which is also why large parts of UIKit and AppKit are now able to be rebuilt on top of it (as recently mentioned by Apple in this year’s SOTU).

Since the issue is gone with Xcode 27 SDK on iOS 27, do you think it still worth filing a FB? @squeakytoy

The latest AppKit debug menu just added a new AG menu item with the json dump and debug server support on macOS 27. (credit @MxIris for sharing this information to me)
Those underlying private API already exist since a very early version of AG. Glad they finally made them more accessible for normal hacky user who enable _NS_4445425547.
For more information about those private API. Go check AGDebugKit.

Glad to know about.
Can't agree any more of the statement of SUI. It is a very amazing software engineer product.
I can then finally PR directly instead of file AG/SUI FB~ or working for Apple.
Hope you can also public the SwiftUI Evolution proposals when open source it so that people can know the design decisions more clearly.

Building a GUI panel for it. The backend is ready.
Trying to integrate it with the GUI element.
Let's ship it in the next release of LookInside. 👊
There is some amazing SwiftUI gesture debug tricks which can help you diagnose gesture issues/conflicts like a master.
A blog post and a corresponding tool will be released soon~
