Fixing Build Errors

Nativeline’s AI automatically fixes most build errors. But sometimes you need to step in. This guide covers manual intervention when automatic fixes fail.

When Manual Intervention is Needed

You’ll need to intervene when:
  • The AI has tried 3 times and still failing
  • The same error keeps recurring
  • The AI is stuck in a loop
  • You understand the problem better than the AI

The Manual Fix Process

Step-by-Step

1

Recognize the Pattern

If you see the AI attempting fixes repeatedly without success, it’s time to intervene.
2

Press Run App

Click the Run App button in the Nativeline interface.
3

Wait for the Popup

A dialog appears asking what you want to do.
4

Click Apply Fix

Select Apply Fix — the AI will automatically analyze the error and attempt a fix.

What Happens Next

The AI will:
  1. Automatically analyze the error
  2. Consider approaches it hasn’t tried
  3. Attempt a new fix
No additional input is required — clicking Apply Fix triggers automatic fixing.

Providing Additional Context (Optional)

Clicking Apply Fix works automatically, but you can optionally help the AI by typing additional context in the chat.

When to Provide Context

If Apply Fix alone isn’t solving the problem, try messaging the AI with details:
This is optional — most fixes work automatically without extra context.

Understanding Common Errors

”Cannot find ‘X’ in scope”

What it means: A variable, function, or type isn’t found. How to help:
or

”Type ‘X’ has no member ‘Y’”

What it means: Accessing a property or method that doesn’t exist. How to help:

“Cannot convert value of type…”

What it means: Type mismatch. How to help:

“Missing argument for parameter”

What it means: Function call is incomplete. How to help:

“Value of optional type must be unwrapped”

What it means: Using a possibly-nil value unsafely. How to help:

When the Same Error Keeps Returning

If the same error persists despite multiple fixes:

1. Try a Different Approach

2. Simplify

3. Remove and Rebuild

4. Work Around It


Using the Code Editor (Pro)

With a Pro plan, you can investigate and fix errors yourself:

Finding the Error

  1. Open Code Editor tab
  2. Files with errors are highlighted
  3. Click to see the exact line
  4. Error message appears inline

Making Manual Fixes

If you spot an obvious fix:
  1. Edit the code directly
  2. Save (Cmd+S)
  3. The app rebuilds automatically

When to Edit Manually

Manual edits work well for:
  • Obvious typos
  • Simple variable name changes
  • Quick value adjustments
  • Adding missing imports
Leave complex fixes to the AI.

Breaking the Error Loop

Sometimes the AI gets stuck trying the same thing repeatedly.

Signs of a Loop

  • Same error message over and over
  • AI making the same changes
  • Undoing its own fixes
  • No progress after multiple attempts

Breaking Out

Option 1: Explicit Different Approach
Option 2: Clear and Restart
Option 3: Manual Intervention If you have Pro plan, make the fix yourself in the code editor. Option 4: Temporary Skip

Preventing Future Errors

Build Incrementally

Don’t request huge features all at once: ❌ “Build a complete e-commerce system” ✅ “Add a product list page” → “Add product details” → “Add cart” → etc.

Be Specific

Vague requests lead to implementation mistakes: ❌ “Make it work” ✅ “Connect the save button to store the form data in SwiftData”

Test Frequently

Check after each change. Catching errors early is easier than debugging cascading failures.

Use Reference Images

Visual references reduce misunderstandings and implementation errors.

When to Start Fresh

Sometimes starting over is faster than fixing:

Signs It’s Time to Rebuild

  • Multiple interconnected errors
  • Fundamental design flaw
  • More time debugging than building
  • The code structure is wrong

Partial Rebuild

Full Restart (Rare)

If the whole project is broken:
  1. Create a new project
  2. Describe your working features
  3. Rebuild more carefully
This is rare but sometimes the fastest path.
