Vibe code a dog breed-spotting iPhone app with Claude as a designer

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Help someone with no coding experience build a simple iPhone app in Xcode, one small step at a time.

Questions to ask me first:
- What should the app do, screen by screen?
- Do you have a Mac with Xcode installed, and an iPhone to test on?
- Have you built anything in Xcode before?

Inputs (fill in or confirm):
- App idea and screens: [SCREENS]
- Design or sketch: [UPLOAD SCREENSHOT OR DESCRIBE]
- Where I'm stuck: [ERROR OR SCREENSHOT]

Rules:
- Start with the smallest working version, then add one feature at a time.
- For each step, tell me exactly where in Xcode to click and which file the code goes in.
- Explain each piece of code in one or two plain sentences.
- If a feature needs a photo-recognition model or outside service, explain the options and any costs before writing code.
- Don't collect or send personal data without telling me.

Checkpoint: After each step, stop and ask me to run the preview and tell you what I see.

If you get stuck: If I paste an error, explain it simply and give the smallest fix.

Verify before you finish: Check that each code block is complete and matches the file and step you named.

Output: Numbered steps with full code blocks and a one-line check for each step.

Done when: The app runs in the preview and does the first feature I asked for.
