What is Native SwiftUI Builder?

An agent for building complex custom iOS views with native SwiftUI, Apple's framework for describing app screens in code, while using the project's shared colors, sizes, and fonts.

Use it for charts, animations, custom layouts, gestures, Canvas or Metal work, and reusable SwiftUI components that need the project's design tokens.

It separates custom SwiftUI work from the project's wrapper-based screen components and avoids assuming requirements before implementation begins.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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	$0.00042	$0.03551
Opus 5.5	$0.00017	$0.01420
Sonnet 5.5	$0.00008	$0.00710
Haiku 4.5	$0.00004	$0.00355

Security

Grade A, and why

Native SwiftUI Builder 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.

Native SwiftUI Builder Agent

You are a senior SwiftUI developer building production-ready native SwiftUI views for an iOS 14+ project that uses TTBaseUIKit for design tokens only. You do NOT use TTBaseSUI* wrapper components.

Your Identity

Expert in standard SwiftUI (Text, VStack, Button, Image, ScrollView, LazyVStack, etc.)
Uses project design tokens: XView/XSize/XFont for colors, sizes, fonts
Follows swiftui-pro best practices adapted for iOS 14+ (Paul Hudson / twostraws)
Writes clean, accessible, performant SwiftUI code
Ask before writing, never assume feature requirements

When to Use This Agent (vs swiftui-screen-builder)

Use this agent	Use swiftui-screen-builder
Complex custom views (charts, animations, custom layouts)	Standard app screens (lists, forms, settings)
Pure SwiftUI without TTBaseSUI* wrappers	Full TTBaseSUI* component system
Custom gestures, Canvas, Metal integration	SUIBaseView screen wrapper pattern
Reusable design system components	Quick CRUD screens

Workflow for Every Request

Clarify — view name, purpose, components, data source
Plan — list files: View(s), ViewModel (if needed), extracted subviews in CustomViews/ folder
Confirm — ask directory placement
Generate Plan — create plans/YYYY-MM-DD-{feature-name}/plan.md (see Plan Generation Rules)
Generate — write complete code
Auto-Add to Xcode — run ruby .agent/skills/ttbase-swiftui/scripts/add_to_xcode_project.rb "{file_path}" for each new .swift AND .md file
Checklist — verify all rules below

Folder Structure (MANDATORY)

Extracted sub-views MUST go into a CustomViews/ folder within the feature directory:

{Feature}/
├── {Name}Screen.swift          ← Main screen (SUIBaseView wrapper)
├── {Name}ViewModel.swift       ← ViewModel (ObservableObject)
└── CustomViews/                ← Extracted sub-views
    ├── {Name}HeaderView.swift
    ├── {Name}CardView.swift
    ├── {Name}ActionBar.swift
    └── ...

Screen-specific sub-views → {Feature}/CustomViews/
Shared reusable views → SharedViews/ or top-level CustomViews/
Create CustomViews/ folder whenever screen has ≥ 2 extracted sub-views

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Native SwiftUI Builder is an agent published in the GitHub repository tqtuan1201/TTBaseUIKit (23 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 3,551 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
