Upgraded app fails to load in iOS, Assertion failed

I tried to upgrade a running app from 7.x to 8.5.2. The app fails to load on iOS (simulator and device) - log below. Here's the environment:
nativescript 8.5.3
@nativescript/core 8.5.3
@nativescript/ios 8.5.2
nativescript-ui-listview 15.2.3

The app fails to load, after the launch event completes, with this log:

====== Assertion failed ======

I've done an ns clean, blown away the package-lock.json, all the usual things clearing hooks, node_modules and platforms. No dice. Please help!

Reproduziere das Upgrade mit den aufgelisteten NativeScript- und iOS-Paketversionen im Simulator oder auf dem Gerät. Beginne bei node_modules/nativescript-ui-listview/index.ios.js:20 und verfolge den Aufruf durch syncListViewLayout und initNativeView, wobei du die zugehörigen @nativescript/core-Pfade vergleichst. Fertig ist die Aufgabe, wenn die aktualisierte App ohne die Assertion geladen wird.
