DuoFix AI
BUILT FOR iOS DEVELOPERS · macOS 14+
DuoFix AI is an adaptive-layout compatibility scanner for iOS developers. Find risky assumptions in Swift and SwiftUI, review a focused fix, and keep control of every change.
Private beta in preparation. No public app download or checkout.
UIScreen.main.bounds
view.boundsIllustrative interface using synthetic code. Not a screenshot or customer result.
IMPLEMENTED TODAY
Review source patterns that deserve attention on resizable displays. Static findings are signals for investigation, not compatibility certification.
Swift source analysis across SwiftUI and UIKit, with 12 rules for geometry, fixed layouts, navigation, safe areas and scene assumptions.
Use deterministic suggestions in supported contexts. Inspect a reviewable code diff, then separately approve patch application.
Rescan to compare findings, keep recovery history and restore matching originals. Export JSON or Markdown reports for review.
FROM FINDING TO REVIEWED CHANGE
Five views of one synthetic example. These are labeled illustrations of implemented workflows, not application screenshots.
Filter by severity, confidence or rule. A high-confidence pattern still needs a developer’s judgment.
LayoutView.swift:21 · UIKit view/controller
let width = UIScreen.main.bounds.widthReview the explanation, source context and suggested action before preparing a proposal.
Main-screen bounds can differ from the app’s available space. Read current view or window bounds during layout.
let width = UIScreen.main.bounds.widthThis match is not proof of a visible defect.
Supported deterministic edits and manually imported AI proposals both produce reviewable diffs. Imported AI output remains unverified.
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
− let width = UIScreen.main.bounds.width
+ let width = view.bounds.width
}Illustrative deterministic suggestion in an existing UIKit layout callback.
Nothing changes just because a proposal was generated or imported. Applying requires a separate confirmation.
This modifies LayoutView.swift. Source hashes are checked and backups are saved outside the project. No build runs automatically.
History persists after restart. Explicit restoration checks originals and current source, refusing unexpected newer changes.

Recovery is not crash-atomic. Avoid concurrent edits during patching.
BUILT WITH BOUNDARIES
Scanning happens on your Mac. The current product does not automatically upload source code. Backups and reports are local and may contain source; protect them accordingly.
Live automatic AI generation is not available. The existing manual workflow exports approved source for you to share separately, then imports structured proposals for review. External providers may process that shared content remotely.
Optional Xcode builds can execute project-provided scripts and plugins. Preview unsigned commands and export them for trusted projects. In-app Xcode execution is currently blocked by App Sandbox.
PRICING INTEREST · NOT A CHECKOUT
We’re testing interest in a free scanner and a proposed $29 one-time Pro upgrade. No payment is accepted. Scope and pricing may change; there is no promise of permanent pricing.
CUSTOMER DISCOVERY
Help shape a controlled private beta. We want to understand your workflow before committing to paid services or final product plans.

Join the Free Beta Waitlist ↗A FEW THINGS TO KNOW
No. It reviews static source patterns. Test actual resizing, navigation, safe areas, accessibility and runtime behavior independently.
No. Live AI execution is disabled. The working AI path is manual source-request export and structured-proposal import, followed by diff review and explicit approval. Supported deterministic suggestions are available separately.
No public download is available. Developer ID signing, notarization and distribution validation are still pending. Signing up does not guarantee a beta invitation or release date.
The hosted form collects only consented research/beta responses under the privacy notice. The current pricing-interest question requires an answer; feedback is optional. Review the contact and unresolved operator/retention details before submitting.
No. There is no checkout, payment processing or purchase commitment. Pricing links open the Tally survey. Choose your preference there; no pricing choice is automatically submitted or prefilled.
