Any ETA on 2017.3.1p1? This is a major problem - iOS builds are unusable until a fix is available but we've made too many changes since we "upgraded" to 2017.3 so downgrading isn't an option.

Not in Fixes nor Known Issues.

UI::ShouldUpdateTransformBefore(TransformAccessReadOnly const&, TransformAccessReadOnly const&)

Looking further, we added the ability to do auto rotation in one of our apps and it seems to cause this problem as well. Not sure if it has something to do with prepositioning the elements before scroll rotation.

Also have the same issue. Downgrading to 2017.2 fixes the problem, but when using 2017.3.0f3 the crash happens on ShouldUpdateTransformBefore().

I have the same issue (2017.3.0p4, iOS 10.3.3 & 11.0.1). This is related to UI CanvasScaler for me. I had to downgrade to 2017.2.1f.

For me crashed on iOS:
SetActive called on already spawned gameObject with TextMeshPro (this one goes with RectTransform) from Coroutine
Reproduced on 2017.3.0p2 and 2017.3.0.p3, .NET 4.6 IL2CPP.
