Describe the problem

I found two errors upon running pod install 1) { "name": "fake_async"error: Sandbox: rsync(35631) deny(1) file-read-data /Users/neil/Library/Developer/Xcode/DerivedData/add2appIosHostTest6July2025-aaaylydgqmtzjtbavnwepzahnxif/Build/Products/Debug-iphonesimulator (in target 'add2appIosHostTest6July2025' from project 'add2appIosHostTest6July2025')

2. [ +50 ms] Flutter failed to write to a file at "/Users/neil/Library/Developer/Xcode/DerivedData/add2appIosHostTest6July2025-aaaylydgqmtzjtbavnwepzahnxif/Build/Products/Debug-iphonesimulator/.last_build_id". Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current user. Try running: sudo chown -R $(whoami) /Users/neil/Library/Developer/Xcode/DerivedData/add2appIosHostTest6July2025-aaaylydgqmtzjtbavnwepzahnxif/Build/Products/Debug-iphonesimulator/.last_build_id

(Previously I did try this sort of permission change but it should be in the instructions if it is needed, and my guess is that it's a red herring and should not be needed

Expected fix

1. Instructions should "just work" like they do in the video, even with Xcode hello world with current stable version of xcode. In other words, I should be able to follow the instructions with little to no knowledge of flutter or xcode or cocoapods, it should be part of hour1 experienced imho.
2. Instructions for cocoapods should also be "simpler" I found it confusing, you had to refer to the sample, if you dont' know what "target" means the "syntax" doesn't help really
3. please consider "quickstart guide' with exactly what to copy/paste rather than "mixed in" with context/explanations
4. Consider a note that swift package manager is coming soon etc. (if it is) and that you can only use flutter attach / hot reload/breakpoitns under x scenarios if in fact that applies etc.

Additional context

flutter stable from July 6 Flutter 3.32.5 • channel stable • https://github.com/flutter/flutter.git Framework • revision fcf2c11572 (12 days ago) • 2025-06-24 11:44:07 -0700 Engine • revision dd93de6fb1 (12 days ago) • 2025-06-24 07:39:37 -0700 Tools • Dart 3.8.1 • DevTools 2.45.1

My Xcode version on this laptop is Version 16.0 (16A242d) but I am pretty I was using "absolute latest" version in the last few days and got last_build_id error.

I would like to fix this problem.

• [ ] I will try and fix this problem on docs.flutter.dev.
