Resolved: Crashes in 3D with iOS 15.4 and the ArcGIS Runtime SDK for iOS and .NET (Xamarin.iOS / Xamarin.Forms-iOS)

Nicholas-Furness · ‎03-31-2022

We have identified an issue displaying a scene view with the ArcGIS Runtime SDK for iOS and the ArcGIS Runtime SDK for .NET (Xamarin.iOS) on iOS 15.4 and 15.4.1. The issue affects iOS and iPadOS devices with an A14, A15, or M1 processor.

[ Update, Apr 13 2022: 100.13.2 released, addressing the fix for iOS and .NET (Xamarin.iOS / Xamarin.Forms-iOS) - see blog ]

[ Update, Apr 12, 2022: We are preparing an update to fix this issue, targeting release on April 13, 2022. ]

[ Update, Apr 5, 2022: We have identified and are assessing a candidate fix. ]

When displaying or interacting with a scene view, the scene view may become unresponsive, or the application may crash.

2D workflows (map view) are not affected.
The ArcGIS Runtime SDK for Qt is not affected.
Only ArcGIS Runtime SDKs version 100.13 and 100.13.1 are affected.
ArcGIS Runtime SDKs version 100.12 and earlier are not affected.
This issue impacts all applications that display a scene view.
No workaround has been identified.

~~We are working to identify the root cause and deliver a fix as a top priority, but at present no ETA is available.~~

[April 5 2022] We have identified and are assessing a candidate fix.

The devices that are impacted are:

iPhone 12, 12 Pro, 12 Pro Max, 12 Mini (2020, A14 Bionic)
iPhone 13, 13 Pro, 13 Pro Max, 13 Mini (2021, A15 Bionic)
iPhone SE 3rd Gen (2022, A15 Bionic)
iPad Air 4th Generation (2020, A14 Bionic)
iPad Air 5th Generation (2022, M1)
iPad Pro 11" 3rd Generation (2021, M1)
iPad Pro 12.9" 5th Generation (2021, M1)
iPad Mini 6th Generation (2021, A15 Bionic)

The device must be running:
