iOS Art Creation & Marketplace App

I’m building a mobile experience that turns a user’s photo into share-worthy, sellable artwork. The project is iOS-only and I’d like it delivered as a clean, well-documented Swift/SwiftUI code-base.

Core capabilities
• Robust photo-editing suite – layers, filters, brushes, adjustment sliders, the works. GPUImage, Core Image or Metal are fine as long as edits feel instant on recent iPhones.
• One-tap social sharing – leverage the native share sheet plus direct hooks for Instagram and Twitter so each post carries a watermark and pre-filled caption.
• In-app artwork marketplace – list, browse, buy. I’ll provide REST endpoints; you handle networking, image uploads (AWS S3 or Cloudinary), and StoreKit for payments. Apple Sign-In will cover authentication.

Deliverables
• Xcode project ready for archive, structured for easy hand-off
• Design assets (Figma or Sketch) that match the build
• TestFlight build signed with development certificates
• README with setup steps, third-party licence notes, and API key placeholders

Acceptance criteria
1. Editing actions complete in under 100 ms on an iPhone 13.
2. Instagram/Twitter post carries correct watermark and caption template.
3. Sandbox purchase flow completes without crash or data loss.

Target timeline: working prototype in 3 weeks, polished beta in 6. If you’ve shipped photo editors, Metal-based filters, or marketplace apps before, please share links or TestFlight codes. Excited to see how you can bring this creative platform to life!
