I have a fully-built iOS application currently sitting on Base44. What’s left is the migration and polishing phase, so it can go live in the App Store. The core of this last stretch is CloudKit work that unlocks native features. Here’s where I need your expertise: CloudKit must be wired up for push notifications and user authentication, and the existing codebase also needs in-app payment integration for Apple. Once those touches are in place, I want a quick performance pass to be sure the app feels snappy before submission. Deliverables I’m expecting • CloudKit configured for push notifications and sign-in • In-app purchase flow working end-to-end and approved in sandbox • Measurable performance optimizations (startup time, scrolling, memory) • An archive ready for TestFlight, followed by a successful App Store submission under my developer account If you’re comfortable tackling CloudKit, in-app purchases, and final performance tweaks in a single sprint, let’s get this app over the finish line. This is not a big project, and I'm expecting a short lead time to completion. Communication is key. If you are not comfortable getting on a video Zoom call, please don't respond.

Hello there, I will wire up CloudKit for push notifications and user authentication, integrate StoreKit 2 for in-app purchases with sandbox testing, and run a performance optimization pass — then package everything for TestFlight and App Store submission under your developer account. For the StoreKit integration, I will use StoreKit 2's async/await API rather than the older transaction observer pattern — it simplifies receipt validation and handles interrupted purchases more reliably. This also makes App Review smoother since Apple favors their newer framework. Questions: 1) Are the in-app purchases consumable, non-consumable, or subscription-based? 2) Is the Base44 export a standard Xcode project, or does it require additional build tooling to compile natively? Ready to start whenever you are. Kamran

Hi there, As you already have the application built, most of the heavy lifting is done. The remaining work is mainly around CloudKit integration, Apple in-app purchases, performance optimization, and getting everything App Store ready, so I can surely help you take it across the finish line. What I will do is configure CloudKit for push notifications and user authentication, set up and test the complete in-app purchase flow in Apple's sandbox environment, review the current codebase for performance improvements, optimize startup time and responsiveness, prepare the archive for TestFlight, and assist with the final App Store submission process under your developer account. Since this is a finishing and migration phase rather than a full build, I expect the turnaround to be quick, and I am completely comfortable joining Zoom calls throughout the process to keep communication clear and progress moving smoothly. I would request to connect once so we can review the current Base44 setup, understand what has already been completed, and create a short roadmap to launch. Thanks, Rahul A.

Hi there, I understand you have a fully built iOS app on Base44 and need the final migration/polishing phase completed, including CloudKit push notifications, CloudKit sign-in, Apple in-app purchases, performance tuning, TestFlight archive, and App Store submission. I have hands-on experience with native iOS release workflows, CloudKit capabilities, StoreKit purchase flows, sandbox testing, Xcode archiving, App Store Connect, and performance profiling for startup time, scrolling, and memory usage. I will review the existing codebase, configure the required Apple entitlements and provisioning, complete CloudKit and payment integration, run sandbox and performance tests, prepare the archive, and communicate clearly through Zoom so the app can move to submission quickly. Q1: Is the app currently in Xcode/native iOS format after Base44 export, or does it still need migration from Base44 first? Q2: Which in-app purchase types are required: consumable, non-consumable, subscription, or auto-renewable subscription? Q3: Do you already have the Apple Developer account, App Store Connect listing, bundle ID, and CloudKit container created? Best regards, Stratos

Hi I can help finish your iOS app migration and polishing phase by configuring CloudKit, push notifications, sign-in, in-app purchases, performance improvements, TestFlight archive, and App Store submission. The main technical challenge is making CloudKit entitlements, containers, notification permissions, Apple account setup, IAP products, sandbox testing, and App Store build signing all work cleanly together. I would start by reviewing the existing Base44 project export, Xcode setup, bundle ID, Apple Developer account configuration, CloudKit container, capabilities, and current app flow. I can wire CloudKit for authentication-related app behavior, configure push notification support, and validate the required provisioning profiles and entitlements. I can implement StoreKit in-app purchase flow, test purchases in sandbox, handle restore/purchase states, and prepare the app for Apple review requirements. I can also run a performance pass focused on startup time, scrolling smoothness, memory usage, unnecessary network calls, and UI responsiveness. I’m comfortable joining Zoom for kickoff, review, and final handoff, and I can communicate clearly through the submission process. Thanks, Hercules

I’ve taken a few apps through this exact “last mile” to App Store, including CloudKit and IAP wiring. Your app sounds essentially done — this is about clean integration and a smooth submission. I’ll hook up CloudKit for auth + push properly (including entitlements, containers, and environment handling), implement Apple IAP end-to-end with sandbox validation, and then run a focused performance pass (launch time, main-thread work, and scroll smoothness). You’ll get: • Working CloudKit (sign-in + push) • IAP flow tested and stable in sandbox • Noticeable performance improvements • Clean archive + TestFlight + App Store submission under your account One thing I’ll keep an eye on: CloudKit schema mismatches between dev and production can quietly break push/auth if not deployed correctly. I’m comfortable jumping on Zoom and moving fast on this. Quick question — is the current codebase SwiftUI or UIKit?
