Unable so as to add iOS platform to Cordova challenge with cordova-plugin-firebasex

The firebasex Cordova plugin is driving me up the partitions! That is the error I get after working Cordova platform add ios:

Failed to put in 'cordova-plugin-firebasex': Error: pod: Command failed with exit code 31
at ChildProcess.whenDone (/Customers/mmhayes/Paperwork/MyQCWeb/MyQC_v6_7/node_modules/cordova-common/src/superspawn.js:136:25)
at ChildProcess.emit (node:occasions:390:28)
at maybeClose (node:inner/child_process:1064:16)
at Course of.ChildProcess._handle.onexit (node:inner/child_process:301:5)

My setting:

Cordova -v
11.0.0

Cordova platform ls
Put in platforms:
  ios 6.2.0
Obtainable platforms: 
  android ^10.1.1
  browser ^6.0.0
  electron ^3.0.0
  osx ^6.0.0

Cordova plugin ls
cordova-plugin-firebase-analytics 6.1.0 "FirebaseAnalyticsPlugin"
cordova-plugin-firebase-dynamiclinks 6.1.3 "FirebaseDynamicLinksPlugin"
cordova-plugin-firebasex 14.1.0 "Google Firebase Plugin"

I imagine the problem has one thing to do with the pod variations however I am undecided. There is not a lot on the net concerning the “exit code 31” error. What little there was, I attempted their advised options with no luck. This included working

Cordova clear
Cordova plugin rm cordova-plugin-firebasex
Cordova plugin add cordova-plugin-firebasex
pod repo replace
sudo gem set up cocoa pods

I do know this goes with out saying, however any assist is way appreciated! I can present extra data about my setting if it will be useful.
