Objective C Jobs

I need a complete mobile app that runs smoothly on both iOS and Android and showcases advanced facial-recognition capabilities. The core of the build is a camera workflow that can: • Face identification • Emotion detection • Age and gender estimation Those three features must fire quickly on-device (or via a lightweight cloud microservice if latency is acceptable) and return an easy-to-parse JSON result I can feed into future modules. The interface should feel modern and sleek with clean typography, subtle animations and dark-mode support. You’ll own the full stack—from selecting the best SDK (e.g., Apple Vision, Google ML Kit, OpenCV, or a custom model in TensorFlow Lite / Core ML) to wiring up the UI in Swift/Kotlin or a unified framework like Flutte...

I have an iOS prototype written entirely in SwiftUI that’s almost ready for prime time, but a few pain-points are holding it back from the App Store. Right now I’m seeing: i made it in openai-codex- i need someone look at the prototype i made, make sure no bugs, all smooth, works well and launch it in the app store - i also need the code from them and access in order to maintain it myself - make sure its all working well efficiently and clean. Launch in app store. then give me code and all for it to maintain myself. Also want someone who can do it in one chunk and happy pay the one off. not paying hourly or extras. • Crashes in several flows • Performance lags on older devices • UI/UX problems that make some screens feel rough Your mission is to hunt ...

Version 1.0 of my SwiftUI app Cut The Line LLC is already on the Store, yet Apple rejected version 1.1 under Guideline 5.1.2 (privacy / tracking). I do not collect or track any user data, so the issue lies in the way my privacy settings are declared. What I need: • Audit the Xcode project (Swift 5, Xcode 15) and ensure any AppTrackingTransparency strings, keys, and data-collection flags are fully aligned with the real behaviour of the app. • Cross-check every data type I selected in App Store Connect and correct anything that might imply tracking. • Prepare a clean, signed build under the existing bundle ID , upload it through Transporter or Xcode, and walk me through the re-submission steps. • Reference the detailed rejection notes I’ll provide so your f...

I have a fully-formed concept for an iOS e-commerce application and I’m ready to move from idea to App Store listing. I need a developer who can guide the project end-to-end—shaping the user experience, writing clean Swift/SwiftUI code, connecting to the necessary back-end services, and ultimately handling the submission process so the app is live and compliant with Apple’s guidelines. You will start by translating my functional outline into low-fidelity wireframes, iterate into polished UI designs, and then build the production app. Throughout the build we’ll keep each feature shippable, use TestFlight for staged releases, and track issues so nothing slips through the cracks. I’ll provide product requirements and timely feedback; you’ll bring technical...

I need a self-contained utility app whose sole purpose is to boost day-to-day productivity. Think quick-fire tools such as smart to-do lists, reminders, or time-tracking widgets—whatever combination will genuinely help users get more done with less friction. Core expectations • Complete end-to-end build: UX/UI, coding, basic QA, and a ready-to-publish package for both iOS and Android (I’m flexible on native Swift/Kotlin versus a cross-platform stack like Flutter or React Native—use whichever lets you ship fastest without sacrificing quality). • Clean, maintainable code and concise documentation so future iterations are straightforward. • A blazing-fast turnaround; I’m looking to move from kickoff to first test build ASAP. If you have a prove...

Build me a cross-platform mobile application that can sit on a phone and cycle through roughly 1,000 video ads every 24-hour period without any manual input. It must run on both iOS and Android, trigger each advert as though a real user pressed play, respect whatever minimum watch-time is required for the payout, and then move on to the next clip automatically. Key requirement • Automate ad watching – the app should open, play, and complete each advert in sequence, handling countdowns, skip buttons, pauses, and reward confirmations so the revenue registers every time. I am open to whatever stack you feel is most stable for a dual-platform release—Flutter, React Native, native Kotlin/Swift, or another proven framework—as long as the final binaries install cleanly ...

My React-based mobile app is already live in TestFlight and fully configured in App Store Connect. I need someone to handle the metadata, screen captures, etc… all the administrative side of getting this submitted. What I now need is a seasoned App Store wrangler who can carry the build across the finish line, deal with the paperwork, and troubleshoot anything Apple kicks back. Here’s the flow I expect: • Review the current build for full App Store Guideline compliance, flagging or fixing issues before submission. • Submit the app through my active Apple Developer account. • Monitor the review queue, respond to Apple’s questions, and resubmit promptly if rejection notes arrive—until the app is approved. • Keep me updated with concise ...

I already have production-ready iOS (.ipa) and Android (.aab) builds, icons, and a style guide. What I need now is someone who can take those assets and carry the release the rest of the way—right through Apple’s and Google’s review queues—without me having to chase any last-minute details. Your responsibilities • Set up or tidy the App Store Connect and Google Play Console entries, linking the correct bundle IDs and package names. • Populate every field in the store listings—title, subtitle, long description, keywords, privacy labels, age rating, content rating questionnaire, and policy declarations. • Prepare and upload device-specific screenshots and promo graphics; you can compose simple mock-ups yourself or resize the artwork I suppl...

I have a production iOS app written entirely in SwiftUI that now needs a round of low-cost but high-quality enhancements. I’m looking strictly for an India-based freelancer who can plug into the existing codebase over Git and work iteratively with me on three parallel tracks: • User-interface upgrades – complete screen redesigns, smoother navigation flow, and richer visual elements while respecting the current colour scheme and Apple’s Human Interface Guidelines. • Bug squashing – tackle the known performance bottlenecks, stamp out intermittent crashes, and polish the minor glitches users keep reporting on TestFlight. • New functionality – once the above stabilises, add a small set of new screens and API hooks that I’ll outline during...

My field crews often find themselves well beyond reliable reception, yet they still need to capture photos and short videos, tag them with a few details, and trust everything will reach our server once a signal returns. I need a true offline-first mobile app—built for both iOS and Android—that keeps every file and form safely on-device, adds it to a robust sync queue, and then reconciles everything automatically when connectivity is restored. Here’s the workflow I have in mind: • While offline, a user can shoot photos or video, enter a caption, select a job site, and hit “Save”. • The app stores each item locally, shows a clear status badge (“Queued”, “Syncing”, “Synced”, or “Conflict”), and lets the...

I need a live feed of every SMS and iMessage that passes through my personal iPhone so I can monitor activity in real time. I have physical and account access to the device; the requirement is purely for my own use. Any method that delivers an immediate, mirrored copy of each message to a Mac, PC, or secure web dashboard is acceptable, provided it stays reliable after iOS updates. The phone currently runs the latest iOS and is not jail-broken, but I’m open to solutions that involve jailbreaking or installing an MDM profile as long as the steps are clearly documented and reversible. Deliverables • A working solution that streams incoming and outgoing SMS/iMessage traffic with only a few seconds’ delay. • Step-by-step instructions so I can reinstall or troubleshoo...

Part-Time Flutter/Node Developer — Ongoing Fixes, New Feature Build & Ad Hoc Maintenance About the Project Global Kirtan App (GKA) is a non-denominational platform for kirtan, sacred sound, and bhakti practice, built for a global audience spanning devotional practitioners, yoga communities, sound healers, and spiritual-but-not-religious users. It's a freemium mobile app combining regular practices, audio/video streaming, a lyrics library with translations, tutorials, event discovery (map + calendar), facilitator and community profiles, and an instrument shop. This isn't a from-scratch build. A working Flutter app already exists with a live backend, and it's been through an independent technical audit — we know its real strengths and its real problems. We&#...

I’m looking for a skilled mobile developer to create (or refactor) a PokerStars-style app that feels just as slick as the desktop platform. My immediate priority is a rock-solid Live Chat function so players can talk to each other seamlessly at the tables. Key points • Build the mobile client from the ground up or improve any existing codebase I provide. • Integrate real-time Live Chat with low latency and minimal battery drain. • Ensure smooth gameplay flow and protect hand data during chat sessions. • I’m flexible on the target platform—if you specialise in iOS, Android, or both, let me know how you’d approach it. Deliverables 1. Fully compiled mobile app. 2. All source code and documented APIs for the chat layer. 3. Brief h...

I manage an online business that communicates with customers almost entirely through WhatsApp Business. I want a reliable freelancer to step in and take full ownership of the message stream, focusing on complaint resolution. Here is what the job looks like day-to-day: each incoming message needs a swift, courteous reply that is tailored to the customer’s exact concern rather than a copy-paste template. You will clarify the issue, offer the correct solution or explanation, and follow through until the customer confirms satisfaction. If something really can’t be fixed on the spot, you’ll flag it so I can intervene, but the goal is to keep escalations to an absolute minimum through solid first-level support. Clear communication records are essential for me to track tre...

I’m looking for an experienced mobile developer to build a full-featured betting application that runs smoothly on both iOS and Android. The core entertainment catalogue must open with colour-prediction games, an in-app casino (roulette, cards, slots, etc.), and a straightforward sports-betting section, with room to plug in additional games later. Key requirements • Unified user system – new players should be able to register or log in with a single profile, then move freely between the different game types. • Secure wallet & payments – deposits, winnings, and all house earnings need to settle automatically into my designated account; please propose a reliable payment gateway / UPI / card solution you have integrated before. • Admin controls &nda...

I’m building a personal goal-tracking app that motivates users through a straightforward points system. A user will be able to set any number of goals (for example, “Run 100 miles” or “Read 10 books”), assign each a target score, and then create daily or one-off activities that earn small or large point values toward that target. At a glance the user should always know two things: their current total and how close they are to completion. The look and feel need to be clean, modern, and visually engaging rather than overly minimalist or playful. I’m leaning toward subtle animations and clear progress visuals—think progress rings, color-coded bars, or simple line charts—to keep the experience motivating without clutter. Authentication will...

I am looking for a seasoned software engineer who can take a utility-focused mobile application from concept to launch on both iOS and Android. The core idea is a practical day-to-day tool, so usability, small footprint, and smooth performance matter more to me than flashy visuals. What I need from you: • A native-quality experience on both platforms—feel free to use Swift/SwiftUI, Kotlin, Flutter, React Native, or another approach you trust, as long as the end result is indistinguishable from a fully native build. • Clean, well-documented source code handed over through Git. • Thorough in-app testing, followed by TestFlight / Google Play internal testing, with any critical issues resolved before public release. • Store-ready builds and a short hand-off gui...

I want to create a compact mobile app that links directly to Instagram and focuses on one key thing: letting users apply high-quality filters and visual effects before they post. Scope and objectives • Integrate Instagram login, media import, and one-tap sharing using the official Instagram API. • Build a fast, intuitive editor with at least 15 adjustable filters plus a handful of eye-catching effects (vignette, blur, color splash, etc.). • Keep the codebase clean so future additions—such as text stickers, cropping, and resizing—can slot in without major rewrites. Deliverables • Fully working iOS or Android app (React Native, Flutter, Swift, or Kotlin—use the stack you’re strongest in). • Source code with build instructions a...

I have a full set of static screenshots that outline every screen, button, and data field of a small personal utility app I want to keep on my own devices. Your job is to transform those images into a fully functioning mobile application that feels native on both Android and iOS. The app itself is simple in concept but must be completely clickable. Each screenshot represents a screen you will recreate, wire together, and make responsive so I can move from one section to another exactly as the images suggest. Key areas include the Reservation ID lookup, a Services list, and a Job Openings board, each reachable through the menu flow shown in the assets. A built-in camera module is essential: when I point the camera at a document’s QR code, the app should read it instantly and route m...
