Introducing AI prompts and recording metadata

The 14.5.0 release is now officially available in the App Store and introduces two significant new features. With AI prompts generated from the Network Monitor you’ll have a first way to benefit from data collected inside RocketSim. Recording metadata allows you to promote your apps with a higher chance of success.

Exporting Network Requests AI Prompts

We’re preparing for the future of RocketSim, in which we bring your Agent tooling closer to the Simulator. RocketSim collects data such as build insights and network requests, which can be incredibly valuable when AI has access to them. We imagine using AI to improve networking, build performance, app design, and more.

The first step is a feature available today: Network Request Prompts.

We’re starting with 3 prompts you can pick from:

1. Redundant calls & caching — Analyze redundant calls and caching opportunities.
2. Performance & overfetching — Analyze performance, overfetching, timeouts, and payload bloat. Highlight the largest bytes out, slowest durations, and fingerprints with varying bytes out.
3. Failures & error spikes — Analyze failures and error spikes, focusing on non-2xx; hypothesize causes (auth, validation, rate limits, server errors) and list next debug steps.

This is just the beginning, and we’d love to hear from you on how we can improve these prompts. Maybe you even know additional prompts we can add.

Privacy-first with heavy redaction

The first thing you might wonder is how we share the network requests within the prompt. Your request contains sensitive data, such as authentication tokens and user data. We don’t want to leak them into any AI tool.

Therefore, we focused heavily on redaction, only sharing what matters for the task we’re executing. Here’s an example prompt:

Analyze redundant calls and caching opportunities. Group by fingerprint; provide table columns: count, cache hint, dedupe window, memoization key. Then recommend batching/conditional requests:

Nothing special in this prompt, or at least, no sensitive data. We optimized the requests for AI to analyze. For example, it contains a fingerprint (e.g. #920d56), which makes it easy to find duplicates.

Reducing token usage

If we shared raw request data, your tokens and context would be easily filled in. We reduced output as much as possible, while retaining enough information for the prompt to be useful.

We’d love for you to try this out and let us know on GitHub in case you find any improvements.

Showing metadata on top of screenshots and recordings

Another wish I’ve had for a while is to showcase the app’s title and website whenever I share a recording of my app. There’s now a new toggle in the side window that allows you to show metadata on top of captures:

Once enabled, RocketSim will try to fill in the metadata based on your most recent build. Additionally, you can provide the metadata to use in the settings for your app’s bundle identifier:

Eventually, once configured, your captures can look like this:

Build monitoring performance improvements

Less visible, but just as important, are the performance improvements we made. RocketSim monitors your builds to provide build insights:

Analyzing your builds used to be quite CPU-heavy, even though we only needed to know whether your build was incremental or clean. In some cases, if you opened RocketSim after a while, RocketSim could run with 100% CPU to analyze all the builds it didn’t read before.

It also turned out that Xcode 26.2 changed the build log format, making it harder for us to determine the build type. Therefore, we revisited this logic completely, resulting in a more reliable analysis pipeline that will never reach 100% CPU. It’s lightning fast!
