Good day, and welcome to NativeScript iOS Daily for July 28th, 2026.
Today's headline: how the runtime handles errors just changed in a way that matters for anyone debugging apps built on it.
PR 409, from Eduardo Speroni, brings the runtime in line with the WHATWG error model — the same behavior you'd expect in a browser. That means unhandled promise rejections and error events now surface properly instead of getting silently swallowed, which has historically been a hard bug to track down. The PR also…
Separately, PR 413 from Nathan Walker updates the bundled Ada URL parser to version four. This is a more contained change, but worth knowing about if you rely on U R L parsing behavior — version four brings upstream improvements from the Ada project, and any parsing edge cases you've worked around may behave…
The commit log today, tied to commit 5-5-F-F-D-E-F, is the same error handling work landing from PR 409 — no separate surprises there.
What's next: watch for follow-up reports on the escape exception path outside the simulator environment, and check whether your app has custom error-handling shims that can now be retired in favor of the built-in behavior.
