Deploy your Swift app to Vercel
Step-by-step deployment help for Swift apps on Vercel. We fix Swift-specific deployment issues, configure Vercel, and get your app live. From $19.
Swift issues we fix before deploying
Common Swift problems that affect Vercel deployments.
Force unwrapping optionals
Using ! to force-unwrap optionals instead of guard let or if let, causing runtime crashes when values are nil.
Storing secrets in UserDefaults
Saving API keys, tokens, and passwords in UserDefaults (plaintext plist) instead of Keychain, making them easily extractable from device backups.
Retain cycles from closures
Strong references to self inside closures and delegate patterns without [weak self] or [unowned self], causing memory leaks that grow over app lifetime.
Main thread blocking
Network requests, file I/O, and heavy computation performed on the main thread, freezing the UI and risking watchdog termination.
Vercel deployment issues we check for
Common Vercel problems that break Swift apps in production.
Serverless function size exceeds 50MB limit
AI tools bundle heavy dependencies into API routes without tree-shaking, pushing serverless functions past Vercel's 50MB compressed size limit and failing the build.
Edge runtime incompatible with Node.js APIs
Generated code uses fs, crypto, or other Node.js built-ins inside Edge Runtime routes, causing deployment failures since Edge only supports a subset of Web APIs.
ISR revalidation not triggering correctly
Incremental Static Regeneration configured with stale revalidate values or missing on-demand revalidation hooks, serving outdated content indefinitely.
Environment variables missing in production
Secrets added to .env.local but not configured in the Vercel dashboard, causing runtime crashes only in production while working perfectly in local dev.

Frequently asked questions
How do I deploy a Swift app to Vercel?
We handle Swift deployments to Vercel end to end. Start with our code audit ($19) to identify deployment blockers specific to your Swift project, then we configure Vercel, fix issues, and get your app live in production.
What Swift issues affect Vercel deployments?
Swift projects commonly have force unwrapping optionals and storing secrets in userdefaults. On Vercel, these combine with serverless function size exceeds 50mb limit and edge runtime incompatible with node.js apis to cause deployment failures.
Can SpringCode deploy my Swift project to Vercel?
Yes. We specialize in deploying Swift applications to Vercel. We audit your codebase for Swift-specific issues, configure Vercel correctly, and handle the full deployment so your app runs reliably in production.
What does Swift deployment to Vercel cost?
Our code audit ($19) identifies all Vercel deployment blockers in your Swift project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
