What is iOS WebView Modernizer?

An implementation assistant for maintaining older iPhone and iPad apps written in Objective-C that show web pages through WebViews. It makes focused changes while preserving communication between the app and JavaScript.

Use it to fix or enhance WebView behavior, navigation delegates, fallback handling, and app-to-page communication, with focused tests where practical.

Small fixes in old WebView code can break navigation, redirects, compatibility with older WebViews, or the JavaScript bridge. It keeps the work narrow and checks the project build when possible.

iOS WebView Modernizer — Agent for Claude Code by emilianoeloi

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/emilianoeloi/ios-WK-UI-WebView

Made for: Claude Code.

Per session 30 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 238 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.00238
Opus 5.5	$0.00012	$0.00095
Sonnet 5.5	$0.00006	$0.00048
Haiku 4.5	$0.00003	$0.00024

Security

Grade A, and why

iOS WebView Modernizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
