How to build an iOS app in 2026 (Complete Guide / with AI)

You are helping me turn one specific YouTube video into real, durable learning.

Source video:
- Title: How to build an iOS app in 2026 (Complete Guide / with AI)
- URL: https://www.youtube.com/watch?v=7OiJtpeiUNw
- Topic: Creative Automation
- My current learning frame: Scope a tiny app that solves a problem you personally have, use an agent to research three shipped versions of its core flow, build one complete end-to-end feature in SwiftUI with a scoped agent, and push it to TestFlight — treating your first App Store rejection as an expected step.
- Why this matters: New playlist item from Cole Caccamise; queued for transcript-backed review, topic mapping, and a practical learning artifact.

Transcript anchors from this exact video:
- 0:48 / Evidence 1: "coming up with the idea. This is something I over complicated for years and is the reason that even though I've been learning to code for something like 8 years now, I've only shipped a couple of apps..."
- 2:57 / Evidence 2: "for specific apps I knew I liked or look at flows like onboarding, subscriptions, checkout settings, and then manually copy and paste screenshots into my AI coding agents. That's now changed because Mobbin introduced their own MCP, which..."
- 4:59 / Evidence 3: "interacts with some external nutrition APIs, I like to build the API first so that I can test these endpoints in my local API client, and iterate with the agent on things like caching. The way that I..."
- 6:51 / Evidence 4: "or if you set up things like review prompts and subscriptions properly. Once you've done enough testing that you think your app is ready to be submitted to the App Store, this is where the hardest part of..."
- 8:42 / Evidence 5: "description if you want to check that out. Once the App Store review process was completed, I was able to release my first iOS app to the App Store, and that's really the easy part these days because..."

Your task:
1. Use the transcript anchors above as the primary source packet. If you add outside context, label it clearly as outside context and keep it secondary.
2. Create a source-check table with columns: timestamp, claim, what the demo proves, confidence, and what still needs verification.
3. Extract the actual teachable claims from the video. Do not invent claims that are not supported by the title, lesson frame, or transcript anchors.
4. Build a reusable learning artifact: A creative workflow board with critique criteria and review checkpoints.
5. Include:
   - a plain-English definition of the core idea
   - a diagram or structured model using this sequence: Brief -> Source -> Generation -> Selection -> Edit -> Taste Review
   - 3 concrete examples that apply the video idea to real agentic work
   - 2 failure modes the video helps prevent
   - a checklist I can use the next time I run Codex or Claude
   - one practical exercise with a clear done signal
6. Add a "learning transfer" section: what changes in my workflow tomorrow if I actually learned this?
7. Add a "source check" section that cites which transcript anchor supports each major takeaway.

Quality bar:
- Make this specific to "How to build an iOS app in 2026 (Complete Guide / with AI)", not a generic Creative Automation essay.
- Prefer operational examples, failure modes, and reusable artifacts over broad definitions.
- Call out uncertainty instead of smoothing over weak evidence.
- If evidence is weak, say what transcript segment or timestamp needs review instead of guessing.
- Finish with a concise artifact I could paste into my learning app.
