Describe the bug

I have a swift file. The total lines are 632, but Claude Sonnet 4 can't output the whole file in one output. I have to ask it to separate output into multiple parts.

I believe Claude Sonnet 4 should output more than that. I want to know if this is a internal limitation of Copilot.

Versions

• Copilot for Xcode: 0.38.0
• Xcode: 16.4 (16F6)
• macOS: 15.6 Beta(24G5065c)

Steps to reproduce

1. Find a swift file with 600 to 700 lines.
2. Revise some parts and let AI to output the whole file.

Screenshots

Breaks at line 564.
