iOS App Rescue
Get an inherited, abandoned or unstable app back into a state where it can build, ship and improve safely.
Independent iOS consultant · London, UK
Senior iOS help when your app needs fixing, assessing or modernising.
I help UK startups and product businesses untangle difficult native iOS problems, from inherited codebases and persistent crashes to Swift 6 migrations and independent technical audits. You work directly with me, and you do not need to commit to a long contract.

Your iOS app does not need another vague recommendation.
It needs someone who can get the project running, separate urgent risk from background noise, and explain what to do next. I can begin with a contained review or investigation, then stay to help with the work if that is useful.
The app is stuck.
It no longer builds, releases are risky, or the original developer has gone.
The team needs clarity.
You need an independent view of architecture, technical debt, security, performance or delivery risk.
The code needs to move forward.
Swift 6, concurrency, SwiftUI or dependency changes are necessary, but a rewrite would disrupt the roadmap.

A senior engineer doing the work
There is no account manager between you and the person reading your code.
- Start with the problem. Share the app, the symptoms, and what decision or deadline is driving the work.
- Make the risk visible. I reproduce, inspect and measure before proposing a solution.
- Leave a useful result. You receive fixes, a prioritised plan, or both, explained clearly enough for the next person to act on.

A short description is enough to start. I will reply by email and let you know whether I can help and what a sensible first step looks like.
