I’m building an iOS experience—written purely in SwiftUI 6—that lets users design, personalise and share their own digital business cards. Your task is to deliver a clean, well-documented Xcode project that achieves the following. • Design hub: Ship at least twenty attractive, ready-to-use card templates. Every template must be fully customisable, supporting live text editing, colour adjustments and image uploads so the user can drop in a company logo or headshot with ease. • Wallet integration: Each finished card should be exportable as an Apple Wallet pass in one tap. • NFC capability: When the phone is tapped against a compatible device, the card must instantly transmit the owner’s full contact vCard; the same tap should also trigger the s...

Python/OpenCV Developer for Mobile Game Automation (macOS) I am looking for a Python developer with experience in computer vision and automation to build a bot for a mobile mini-game. The game runs on an iPhone that is mirrored to my Mac using iPhone Mirroring (macOS Sequoia). The bot would run on macOS and interact with the mirrored game window by detecting visual elements and triggering clicks. There are a few mini-games in the app. Each game lasts about 30–60 seconds. Example mini-games: Timing Game: A meter moves back and forth with a white indicator. When the indicator reaches a colored zone (orange or purple), the bot should click at the correct moment. The closer the click is to the center of the zone, the higher the score. Mole Game: Moles appear on screen and need to b...

I have a personal apple developer account . Now we have deveoped and app and I want to test in testflight. but the issue is we can't share the password of the personal account. I can give you the app store connect admin access, .p12 keychain, provisioning file etc. Your main work would be launching the app in testflight with these as we have failed and don't know properly how to do that in a personal account .

I’m ready to move from concept to code on a brand-new productivity app and need a developer who can deliver a polished experience on both iOS and Android from day one. At its core, the app must let users create and track tasks, view and sync those tasks with their calendar, and collaborate seamlessly with teammates in real time. The flow should feel effortless: • quick task capture with priorities and due dates, • automatic calendar updates so schedules stay in sync, • shared workspaces where team members can comment, attach files, and see progress instantly. A clean, distraction-free interface is vital; think intuitive gestures, subtle animations, and fast load times even on older devices. Whether you prefer Swift + Kotlin, Flutter, or React Native, I’m o...

I need a polished social media application released simultaneously on iOS and Android. The core experience revolves around three pillars—real-time messaging, effortless photo/video sharing, and a scrollable news feed that feels lively yet intuitive. Smooth in-app camera access, reactions, push notifications, and quick media loading are all part of the vision. For sign-up and security, the app must support: • Email & password accounts • Social-media single-sign-on (e.g., Apple, Google, Facebook) • Phone-number verification with OTP A clean architecture, secure REST/GraphQL API layer, and a scalable database are non-negotiable. Whether you prefer Flutter, React Native, Swift/Kotlin, or another modern stack, performance and UI consistency across devices come...

I’m looking to have a social networking app built from the ground up for both iOS and Android. The core concept is straightforward: users create profiles, connect with friends, and share posts in a scrolling feed. Here’s what I need: • A clean, intuitive front-end written natively or in a proven cross-platform framework (Swift/SwiftUI + Kotlin, or React Native/Flutter if you prefer). • Basic account management with email or phone verification, plus options to log in with Apple and Google. • Real-time feed where users can post text, images, or short videos, like and comment, and see updates instantly. • Simple search to find other users by name or username and send connection requests. • Push notifications for new likes, comments, and connec...

I need a single app that runs on both iPhone and Android and blocks spam or unknown callers automatically. Whenever a call comes in, the app must check two sources in real time: • the device’s own contact list • a cloud-based “safe numbers” database I already host (REST endpoint provided) If the number appears in either source, the phone rings as normal. If not, the call is silently routed straight to voicemail. Every incoming attempt—allowed or blocked—should be logged inside the app so the user can review which numbers tried to get through. Core requirements • Native-feeling solution that complies with CallKit / Call Directory Extension on iOS and the equivalent Telephony APIs on Android so filtering keeps working even when the app ...

Necesito una aplicación de topografía nativa para iPhone que permita a los usuarios: • Medir distancias con precisión usando la cámara o el GPS del dispositivo. • Realizar nivelación automática mostrando la desviación en tiempo real. • Navegar sobre un mapa interactivo donde puedan situar y guardar puntos de interés. La captura de datos será principalmente mediante entrada manual en formularios claros y rápidos; sin embargo, el código debe quedar preparado para que más adelante podamos añadir voz o sensores si el proyecto crece. Al finalizar cada sesión, la app generará informes detallados en PDF y/o Excel con toda la información recolectada, listos para com...

I need a clean, minimalistic animated highlight for the five-item bottom navigation bar in my iOS app (Routes, Activity, Navigate, Challenges, Profile). When a user taps a tab, a rounded rectangle should slide to the new position with a springy, slightly bouncy motion that feels fluid at 60 fps. The highlight will stay a single, neutral accent color; no per-tab color changes are required. Please implement this in Swift (UIKit or SwiftUI—whichever you prefer) and deliver: • fully-commented source code or a small demo project showing the component in action • integration notes so I can drop the view into my existing codebase without breaking Auto Layout or Safe Area constraints Acceptance criteria: the animation must start the moment a tab is pressed, complete smoot...

Title: Simple iOS Habit Tracker App (Farm / Tree Concept) Description: Hello, I’m looking for a developer to build a simple MVP iOS app. The concept is a habit challenge app where users break bad habits and build good habits using a farm/tree system. Main idea: Users select up to 4 habits. Each habit has a small farm with 30 plots. Every successful day plants a tree in the farm. Over time the farm fills with trees showing the user's progress. Features (MVP): • Up to 4 habits per user • Daily button: "Done for today" • Farm with 30 plots per habit • Tree appears when the user completes the day • Small achievement messages • Simple history/calendar view • Local storage only (no login, no backend) Platform: iOS only (first version...

I want a lightweight iOS-only application that guides users through a 30-day “break the habit” challenge. A user can enter up to four habits at the start; from there, each calendar day presents a single confirmation screen. When the user logs success for all chosen habits that day, an illustrated tree grows—advancing to a new stage every seven consecutive successful days and unlocking a small achievement badge. Core flow • Welcome screen → add (or edit) up to four habits • Daily check-in screen with a single, clear “Done for today” interaction • Animated tree that visually grows at days 7, 14, 21, 30 • Simple history view summarising which days were completed or missed The interface should stay clean, friendly and motivat...

Estoy atascado con la validación de las transacciones de las compras in-app de mi aplicación iOS. Los productos ya aparecen en App Store Connect y la interfaz de usuario de compra se muestra sin problema, pero al procesar la operación me devuelve errores de validación y la transacción no queda registrada correctamente. Necesito que revises conmigo la configuración actual en App Store Connect y el código que uso con StoreKit / Swift. El objetivo es: • Detectar y corregir la causa de los errores de validación. • Ajustar la lógica para registrar y finalizar las transacciones de forma segura. • Probar las compras (incluida la restauración) en el entorno sandbox hasta que queden completamente funcionales....

I’m kicking off a brand-new social networking mobile app and want to start with one rock-solid cornerstone: user profiles. Your task is to design and code this core module so we have a clean, extensible foundation for all future features. Here’s what I need from you: • A fully functional profile screen where users can view and edit their photo, bio, and basic details. • Secure account creation and authentication (email, Google, or Apple—whichever you’re most comfortable implementing first). • Simple back-end or cloud setup to store and fetch profile data reliably. • Clear documentation and commented code so any developer joining later can pick up where you leave off. • A short walk-through video or call at hand-off showing how eve...

I have a live SwiftUI-based social app that already ships chat, video feeds, stories, live scenes, an in-app currency (stars) and subscription flow. The code follows MVVM, talks to a set of REST back-ends and is in the store today. What I need now is an experienced iOS engineer who can drop into the existing project, diagnose issues quickly and raise the overall quality bar. The immediate focus is three-fold: • First, do a thorough walkthrough of the current codebase so you understand our MVVM layers, networking helpers and IAP logic. • Next, remove bugs that are spiking our crash reports and tighten up general stability. • Finally, tune performance in the chat and media areas, then layer in a handful of small feature requests we already have queued for those modules....

I want to swap the live camera feed on an older, jail-broken device (iOS 13–14 running Dopamine or a similar rootless setup) with a predefined asset so I can study how iOS handles media input. The tweak should let me point the system camera APIs to either: • a single static image (JPEG or PNG) • a looping video file (MP4) Ideally I can drop the asset into a folder or set its path in a simple prefs bundle, then toggle between “live”, “image”, and “video” without rebooting. No need for App Store integration, entitlement trickery, or third-party service hooks—this stays strictly on-device for personal, non-commercial testing. Deliverable • Rootless .deb that installs cleanly on Dopamine • Preference pane (or command-li...
