Deploy your Swift app to Railway
Step-by-step deployment help for Swift apps on Railway. We fix Swift-specific deployment issues, configure Railway, and get your app live. From $19.
Swift issues we fix before deploying
Common Swift problems that affect Railway 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.
Railway deployment issues we check for
Common Railway problems that break Swift apps in production.
Nixpacks detects the wrong build system
Monorepo projects or apps with multiple package managers confuse Nixpacks auto-detection, resulting in incorrect build commands and failed deployments.
Volume data lost on redeploy
AI-generated apps store uploaded files or SQLite databases on the filesystem without configuring Railway volumes, losing all data on each new deployment.
Private networking misconfigured between services
Internal service communication uses public URLs instead of Railway's private network (*.railway.internal), adding latency and exposing internal APIs publicly.
Health check endpoint missing
Railway restarts services that fail health checks. AI-generated servers often lack a /health endpoint, causing unnecessary restart loops.

Frequently asked questions
How do I deploy a Swift app to Railway?
We handle Swift deployments to Railway end to end. Start with our code audit ($19) to identify deployment blockers specific to your Swift project, then we configure Railway, fix issues, and get your app live in production.
What Swift issues affect Railway deployments?
Swift projects commonly have force unwrapping optionals and storing secrets in userdefaults. On Railway, these combine with nixpacks detects the wrong build system and volume data lost on redeploy to cause deployment failures.
Can SpringCode deploy my Swift project to Railway?
Yes. We specialize in deploying Swift applications to Railway. We audit your codebase for Swift-specific issues, configure Railway correctly, and handle the full deployment so your app runs reliably in production.
What does Swift deployment to Railway cost?
Our code audit ($19) identifies all Railway deployment blockers in your Swift project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
