SwiftUI developer for a stock watchlist app built for iPhone Duo (foldable)

@c0909h1179

The hard part here isn't the watchlist CRUD — it's a layout engine that stays fold-safe and readable across compact outer and split inner displays, with Swift Charts scrubbing that still feels precise near the hinge. Quote: Option A — $1,500, 3.5 weeks; Option B — $2,000, 6 weeks. Approach: (1) translate your 6-pose wireframes into one layout resolver driven by scene posture, size classes and GeometryReader; (2) build the data layer against your market API proxy — caching, live/after-hours refresh, alerts via local notifications; (3) ship TestFlight at milestone two, then App Store submission plus 30 days of fixes. Pose detection: read the scene's posture/hinge state combined with size class and orientation, with Core Motion tilt to separate Tent, Flat and Laptop. Since 2008 I've shipped 80+ apps, several SwiftUI and iPad multitasking builds — links on request. Which market data provider are you using?

Hello, I’d be happy to build your polished SwiftUI stock watchlist app for iPhone Duo, following the supplied wireframes and Apple’s adaptive layout principles. Option A – Adaptive Fixed Price: $2,500 Timeline: 3–4 weeks Adaptive outer/inner layouts Watchlist, search, sorting, sparklines & live prices Stock details with Swift Charts and 1D–MAX scrubbing REST market API integration Price alerts/local notifications Dark/Light Mode, Dynamic Type & VoiceOver TestFlight + App Store submission support 30-day bug fixes Option B – Pose-Tuned Fixed Price: $4,000 Timeline: 5–6 weeks Everything in Option A, plus dedicated layouts and animated transitions for all 6 poses. Pose detection: I’d use the device’s available posture/orientation and window/layout geometry signals to determine the active pose and switch the appropriate SwiftUI layout. Relevant App Work: I can provide verified SwiftUI/App Store examples upon request rather than claiming unverified links. Best regards, Bivanshi Ohri

Dear Client, I read "SwiftUI developer for a stock watchlist app built for iPhone Duo (foldable) — fixed price" carefully and understand you are looking for a full-stack developer who can handle both application development and AI integration. I have experience with Mobile App Development, iPhone, iOS Development, Mobile Development, App Development and can work across the complete stack — frontend, backend, APIs, databases, authentication, third-party integrations and AI features. I can build scalable applications using modern technologies while keeping the codebase maintainable and production-ready. A few quick questions: Which AI models/APIs are you currently planning to use? Is there an existing application/codebase, or will the project be built from scratch? Thanks & Regards, Deepak

I see you're looking to develop a stock watchlist app specifically for that iPhone Duo, using SwiftUI and Swift Charts. The challenge of adapting the layout for both the outer and inner displays while following Apple's guidelines is key, I’ve worked on similar projects, and I know that handling transitions between the different poses can be kind of tricky, especially making sure the UI remains responsive and intuitive. So for this project, I’ll create a polished app that meets your requirements, focusing on the watchlist features and stock details. I’ll also implement the price alerts and make sure the app supports both dark and light modes. My approach will include thorough testing and support for the App Store submission process, plus those 30 days of bug fixes post-launch. I'm ready to get started on this right away, and I think it’ll be a great collaboration. Rajavel, SwiftUI Developer | Swift Charts | REST API Integration.

Hi, I looked at your requirements and understand that the key challenge is building a polished stock experience that adapts correctly to the iPhone Duo’s different display configurations without making the app unnecessarily complex. I can build the SwiftUI app with Stock List and Stock Details, REST market-data integration, watchlist management, charts, alerts, notes, dark/light mode, Dynamic Type, VoiceOver, and the required API-key proxy. For Option A, I’d use adaptive SwiftUI layouts with a compact outer-display experience and regular inner split view. For Option B, I’d add pose-specific layouts and controlled transitions while keeping the underlying components reusable. For pose detection, I’d use the device’s scene/window geometry and orientation/fold-state information exposed by the platform, rather than relying only on screen rotation. Option A: $1,400 fixed — 3–4 weeks Option B: $1,900 fixed — 5–6 weeks Two quick questions: Can you share the six wireframe poses and the market-data API you plan to use? Do you already have the iPhone Duo test device available for development and TestFlight validation? Jonas Dedzo

@MagCloud

Hello, I’d be excited to build your iPhone Duo stock watchlist app using SwiftUI and Swift Charts, with a strong focus on polished UX, performance, accessibility, and reliable market-data integration. Option A — Adaptive Compact outer-display layout Regular inner-display split view Side-rail controls and fold-safe layout Watchlist, search, reorder, sorting, tags, sparklines, market status, live/after-hours prices Stock details with 1D–MAX charts, scrubbing, stats, financials, earnings, and notes Local price alerts, notifications, Dark/Light Mode, Dynamic Type, and VoiceOver REST API integration, API-key proxy, TestFlight, App Store support, and 30-day bug fixes Fixed price: $4,500 Timeline: 3–4 weeks Option B — Pose-Tuned Includes everything in Option A, plus unique layouts for all six poses and animated transitions. Pose detection: I would use the device’s window size, orientation, screen traits, and available posture/fold-state APIs exposed by the iPhone Duo SDK, with a safe fallback when posture data is unavailable. Milestones can be structured around design approval, functional TestFlight build, and launch submission. I can provide source code, documentation, App Store submission assistance, and post-launch fixes. I can share relevant SwiftUI/App Store examples during discussion. Regards, Mohit G

Hi, "Pose-Aware Watchlist App" - keep the two-screen stock workflow fast and readable across the Duo's changing display states. I can handle the watchlist, stock details, REST API integration, charts, alerts, accessibility and responsive mobile UI. I would use device/window geometry and interface traits to determine the active configuration rather than hard-coding a single screen size. My confirmed mobile stack is React Native/Flutter; I do not want to falsely claim shipped SwiftUI apps, so I cannot provide the requested two SwiftUI App Store links. For pose detection, I would derive the pose from the device's available geometry, orientation and posture/window configuration rather than relying only on rotation. Would you consider a developer with strong mobile/API experience who is transparent about not having two shipped SwiftUI apps? Artur Gizycki

@manh2906

Hello, I am Manh. The main goal is a polished SwiftUI watchlist built specifically around iPhone Duo’s changing screen configurations, while keeping market data, charts, alerts and accessibility reliable across every supported layout. For Option A, I’d build a shared adaptive SwiftUI architecture using size classes, scene/layout information and fold-aware geometry to switch between the compact outer view and inner split layout. For Option B, I’d extend that foundation with pose-specific layouts and controlled transitions rather than duplicating screens. I’d integrate the market-data REST API, Swift Charts, search/sort/reorder, sparklines, live/after-hours data, alerts with local notifications, notes, Dynamic Type, VoiceOver and dark/light modes. I would structure delivery around the supplied wireframes: core UI → API/data layer → alerts/charts → TestFlight → App Store support and bug-fix period. Option A: $1,500 / 3–4 weeks. Option B: $2,000 / 5–6 weeks. I don’t have two specific shipped SwiftUI app links to provide, so I’d rather be transparent. Pose detection can be driven by the device’s current geometry/scene configuration and fold-aware layout information.

@ankits0192

Hi there. I am Ankit. I see you need a SwiftUI stock watchlist app built specifically for iPhone Duo, with adaptive and pose-tuned layout options, live market data, charts, price alerts, and full accessibility support. This is a native iOS project requiring strong SwiftUI and Swift Charts experience, plus shipped App Store apps and ideally foldable or iPad multitasking work. Since my background is in web and software development rather than native iOS, I cannot deliver the quality you need here. If a web-based companion dashboard or API proxy layer becomes part of the scope, I would be glad to help there. Let's discuss in more detail now.

@RohanBoy17

Hello, I can develop your iPhone Duo stock watchlist app using SwiftUI, Swift Charts, and market data APIs, with accessibility, Dynamic Type, dark/light modes, alerts, and smooth responsive layouts. **Option A – Adaptive:** $1,200 | 3–4 weeks **Option B – Pose-Tuned:** $1,800 | 5–6 weeks I’ll provide source code, TestFlight builds, App Store submission support, and 30 days of bug fixes. Pose detection can use window size, orientation, and device scene/layout changes. With 5+ years of development experience, pricing is flexible. I prefer to share verified portfolio links rather than claim unverified shipped SwiftUI apps. Best regards, Rohan M.

@mayankinnovative

I understand this is a focused, polished SwiftUI stock watchlist built specifically for iPhone Duo, with market-data API integration, fold-aware layouts, accessibility, alerts, and a clean App Store delivery. I’ll build both with SwiftUI + Swift Charts, implementing the complete watchlist and stock-detail flows, live/after-hours pricing, charts with scrubbing, alerts/local notifications, notes, dark/light mode, Dynamic Type and VoiceOver. I’ll keep API handling secure through the API-key proxy and structure the code for maintainability and smooth performance. For pose detection, I’d use the device’s window/layout environment and scene geometry/orientation signals to determine the active posture, then drive the appropriate SwiftUI layout and transitions. I’ll provide source code, TestFlight builds, testing, App Store submission support and 30 days of post-launch bug fixes. Ready to deliver either option cleanly from development through launch.

@sara0346

Hello, I reviewed your SwiftUI stock watchlist app for iPhone Duo. I will build the two-screen app with SwiftUI and Swift Charts, integrating the market REST API for watchlists, live and after-hours prices, sparklines, detailed charts, alerts, notes, Dynamic Type, VoiceOver, and light/dark mode. Option A will use adaptive outer/inner layouts, while Option B will add six pose-specific arrangements and transitions. I’m ready to start immediately and will deliver source code, TestFlight builds, App Store submission support, and 30 days of bug fixes. For pose detection, I will use the device’s window geometry, orientation, and hinge/posture information to select the appropriate layout. Could you provide the market API documentation and wireframes? Best Regards, Sara
