When I run flutter build ios I get this failed output:

Error running pod install

Whats odd is I was running builds for a few weeks no problem. I had to update some plugins inside the pubspec.yaml file then it all broke when building ios

I immediately googled my answered and found this stack overflow question here: Flutter Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified

They mentioned to:

You should uncomment your profile ios target.

I had already had that un-commented and set to platform :ios, '11.0'

I then did some more research and it looks like it could be a Mac M1 Chip issue: How to run CocoaPods on Apple Silicon (M1)

I followed the 2022 instructions there:

# Uninstall the local cocoapods gem
sudo gem uninstall cocoapods

# Reinstall cocoapods via Homebrew
brew install cocoapods

This failed and I think brought me into a bigger hole so I ran flutter doctor

I then clicked on the link and followed the instructions to update cocoa pods.

sudo gem install cocoapods

But if I run flutter doctor again, it still says its out of date...

Think I am in a worse place now.

Could you restart your mac, run "gem which cocoapods" and tell me the output? This will check which kind of cocoapods is currently installed. And restarting/relogging might be helpful to load the newly installed version — jraufeisen, Nov 17 '22 at 00:30
On further thought, I would suggest a complete deinstallation and reinstallation of cocoapods. It seems to me that you have two conflicting versions (one via "brew install ..." and one via "gem install"). You can use "gem uninstall cocoapods" and "brew uninstall cocoapods" to uninstall. Afterwards, run flutter doctor again to verify there is no installation present. Then reinstall via gem install. — jraufeisen, Nov 17 '22 at 00:35
I would assume that you have an outdated brew version which causes you to load an old version (1.5) of cocoapods. Might be worth to run brew update / brew upgrade — jraufeisen, Nov 17 '22 at 00:35
@jraufeisen tried all that then had issues trying to run brew update: https://pastebin.com/PnPJtPig — Ten Digit Grid, Nov 17 '22 at 00:41
Try the gem command with sudo in front of them. So "sudo gem uninstall cocoapods". For the brew error, try "rm -rf $(brew --repo homebrew/core)" followed by "brew tap homebrew/core". More info on the brew problem here: https://github.com/Homebrew/discussions/discussions/1512 — jraufeisen, Nov 17 '22 at 00:52
so looks like I got back on track with cocoapods: https://pastebin.com/4Vz8J1hh Still having issues now with flutter build ios which gave me this: https://pastebin.com/rmNuUXjE Then I ran: pod repo update but I still get build error after — Ten Digit Grid, Nov 17 '22 at 01:02
I am running pod update Firebase/Firestore Right now. Its takign awhile but fingers crossed this fixes it — Ten Digit Grid, Nov 17 '22 at 01:09

To summarize a few keypoints here:

Your cocoapods installation was broken. So try removing the brew version first via "brew uninstall cocoapods" Then install cocoapods via sudo gem install cocoapods.
Your Podfile is referencing two different versions of the same package.

  [!] CocoaPods could not find compatible versions for pod "Firebase/Firestore":
      In snapshot (Podfile.lock):
        Firebase/Firestore (= 9.3.0)
 
      In Podfile:
        cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 4.0.5, which depends on
          Firebase/Firestore (= 10.1.0)

This might also cause the build error. You could try to find versions of the plugins snapshot and cloud_firestore that don't conflict with one another.

thanks for all the help. Attempting this right now: You have either: * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`. * changed the constraints of dependency `Firebase/Firestore` inside your development pod `cloud_firestore`. You should run `pod update Firebase/Firestore` to apply changes you've made. — Ten Digit Grid, Nov 17 '22 at 01:11
