My Flutter app is not working on my iOS device, while its working perfectly on android. I'm getting an error on pod install
This is the output of pod install --verbose

Resolving dependencies of `Podfile`
[!] CocoaPods could not find compatible versions for pod "Firebase/CoreOnly":
In snapshot (Podfile.lock):
Firebase/CoreOnly (= 5.20.2)
In Podfile:
firebase_auth (from `.symlinks/plugins/firebase_auth/ios`) was resolved to 0.0.1, which depends on
Firebase/Auth (~> 6.0) was resolved to 6.0.0, which depends on
Firebase/CoreOnly (= 6.0.0)
It seems like you've changed the constraints of dependency `Firebase/CoreOnly` inside your development pod `firebase_auth`.
You should run `pod update Firebase/CoreOnly` to apply changes you've made.

- family: WorkSansMedium
fonts:

The error is happening mainly because of a conflict between cloud functions and authentication firebase libraries.
I'm totally new to pod, and can't seem to find a solution online of my case. I've tried the answer from https://stackoverflow.com/a/40102370 but it did not work.
Any recommendations on how to fix this?
回答1:
Go to your flutter project. Navigate to ios and open Podfile Replace the second line of that file with this:
platform :ios, '10.0'
simple_permissions doesn't work for iOS versions below 10.0
回答2:
It worked for me after delete Podfile.lock file and Pod directory, and again install pod manually using pod install command.
回答3:
Try to use these command in terminal :
rm -rf ~/.cocoapods/repos
pod setup
回答4:
uncomment the ios version from the podfile
platform :ios, '9.0' // ios/Pods/podfile
and then install the pods using
pod install
and then try running the app
回答5:
I have the same issue.
You should not let pubspec.yaml versions set to "any". After resolving the versions, you should fix it to have it stable.
回答6:
Simply uncommenting line 2 of Podfile worked for me.
回答7:
Changed this from platform :ios, '9.0' // ios/Pods/podfile
to platform :ios, '10.0' // ios/Pods/podfile
And it worked for me. Thanks, Guys.
