I already have a functioning VPN app in the App Store and now need a skilled iOS developer to take it to the next stage. The immediate priorities are: • Integrate Apple’s StoreKit framework so users can purchase and manage subscriptions from inside the app. The flow must cover free-trial, monthly and yearly plans, handle renewals, restore purchases and surface any StoreKit errors gracefully. • Add a one-tap speed test that pings every available VPN server, displays latency / throughput in real time and caches the latest results for quick comparison. • Implement automatic server selection that chooses the fastest available node at launch or whenever the current connection drops, with a seamless hand-off so the user never notices the switch. The existing codebase is in Swift and already handles encryption, tunnelling and basic server switching, so you’ll be extending rather than rewriting. Clean, modular code, Git-based commits and concise inline documentation are essential because the project is actively maintained by multiple developers. Deliverables will be a pull request that builds without warnings in the latest Xcode, passes our unit tests and is ready for TestFlight. I’ll provide access to the private repo, current provisioning profiles and a test server set. Once merged, we’ll run a quick smoke test together before submitting to Apple review. If you have previous StoreKit or VPN experience, let me know—otherwise I’m happy to walk you through the existing architecture.

Hi — I can upgrade your App Store VPN app to add in‑app subscriptions (StoreKit), a one‑tap speed test that pings all servers and caches results, and automatic fastest‑node selection with seamless hand‑offs. - As an experienced full‑stack developer I work in Swift, deliver clean, modular code with concise inline docs, and follow strict Git-based workflows. - I produce PRs that build cleanly in Xcode, include unit tests and atomic commits suitable for an actively maintained repo. - Comfortable implementing network/real‑time features (latency/throughput measurement), local caching and integration with existing tunnelling logic. Plan: - Approach: Implement subscription flows (free trial, monthly, yearly, restore, error handling), add parallel ping/throughput tester with realtime UI and cached results, then add automatic fastest-node selection with seamless reconnect. - Milestones: three focused PRs (StoreKit → Speed Test → Auto‑Selection) each with unit tests and docs. - Quality: zero-warnings build, pass unit tests, TestFlight-ready; we'll run a joint smoke test before Apple submission. Questions: 1) Minimum iOS and Xcode versions (StoreKit1 or StoreKit2 preference)? 2) How many servers and do they expose health endpoints or only raw IPs? If that works, grant repo access and I’ll open a feature branch and first PR within 48 hours. You can check my reviews on my profile.

Dear Hiring Manager, I am ready to start work today and help take your existing App Store VPN app to the next level. With solid experience in Swift development, StoreKit integration, and VPN workflows, I can implement the features you need while maintaining clean, modular, and maintainable code. Here’s how I can contribute: StoreKit Integration: Full subscription handling including free trials, monthly/yearly plans, purchase restoration, renewal management, and graceful error handling. One-Tap Speed Test: Real-time latency and throughput checks for all available VPN servers, with caching of results for instant comparison. Automatic Server Selection: Intelligent selection of the fastest server at launch or during connection drops, ensuring seamless hand-offs without interrupting the user experience. I will work directly on your existing Swift codebase, extending it without rewriting, and deliver a pull request ready for TestFlight that builds cleanly in the latest Xcode, passes unit tests, and is fully documented for team collaboration. Git-based commits and concise inline documentation will ensure your multi-developer workflow remains smooth. Previous experience includes App Store VPN apps and subscription management, so I understand both StoreKit nuances and VPN network logic. My focus is quality, stability, and a seamless user experience. Best Regards, Jagrati

Hello There, I totally understand your requirement and the pain point here: your VPN already works, but the next stage needs to feel rock-solid, Apple-compliant, and invisible to the user. StoreKit flows breaking, slow server picks, or clunky failovers are exactly what cause churn in VPN apps—and fixing those properly requires extending the existing architecture, not hacking around it. I’ve worked on a Swift-based VPN and connectivity app where my responsibility was adding StoreKit subscriptions (trial, monthly, yearly), handling edge cases like failed renewals, restore purchases, and App Store review quirks. In the same project, I implemented a background latency probe to rank servers and auto-switch on drop without user-visible reconnects. That app passed review cleanly and scaled to thousands of active subscriptions. For your app, I’d: Integrate StoreKit with clean abstraction, full error handling, and receipt validation Build a fast, cached server speed test with real-time metrics Implement automatic fastest-node selection with seamless fallback Follow strict Git hygiene, modular Swift code, and inline documentation Let me know when you’re available to discuss this further I’d be happy to walk you through my approach or showcase examples relevant to this project. Looking forward to hearing from you! Best regards, Mulayam

I’ve reviewed your requirement and this is my understanding: you already have a live iOS VPN app on the App Store, built in Swift, with core encryption, tunnelling, and basic server switching in place. You’re now looking for an experienced iOS developer to extend the existing codebase—not rewrite it—by adding in-app subscriptions via StoreKit, intelligent performance testing, and automatic server selection that improves reliability and user experience without disrupting active connections. I have 8+ years of experience in iOS development with deep hands-on work in StoreKit (subscriptions & trials), networking-heavy apps, and performance-sensitive Swift codebases. I’m comfortable working inside existing architectures, following established patterns, and delivering clean, modular changes suitable for long-term maintenance by multiple developers. I’m also happy to review your current StoreKit readiness and server architecture before starting to flag any potential Apple review risks early. Best Regards, Deepak

Hi there, I can extend your existing Swift VPN app without disrupting the current architecture. I’ve integrated StoreKit (free trials, monthly/yearly plans, renewals, restore, error handling) and built real-time speed tests + auto-server selection for production iOS apps before. I’m a senior iOS developer, comfortable with StoreKit 2, networking, and clean modular Swift. I’ll deliver a warning-free PR, Git commits, inline docs, and a TestFlight-ready build that passes tests. I can start immediately and adapt to your current repo structure. Happy to review the codebase and move fast. Thanks Amul
