Fix “Cycle Inside“ Error in Xcode

Error

Cycle inside CustomerArea; building could produce unreliable results.

Complete error

Cycle inside CustomerArea; building could produce unreliable results.
Cycle details:
→ Target 'CustomerArea': ExtractAppIntentsMetadata
○ Target 'CustomerArea' has copy command from '/path' to '/path'
○ That command depends on command in Target 'CustomerArea': script phase “script name”

Problem

This error happens because there is an issue with the order of scripts in the Build Phases section.

All these scripts will run serially (one after the other), and you can change the order by grabbing the run script and moving it up or down.

So probably, this error is thrown because one script depends on another one that is placed after thus it throws an error.

Solution

To solve it:

1. In the Navigator sidebar select your project
2. Then, select the Build Phases section
3. Then check the error message and look what script is causing the error
4. Finally move that script to a later position
5. Rebuild and check if the error is thrown
6. If the error persists try moving the script again down the list

Hopefully this will fix the error.
