Please specify a platform for this target in your Podfile?

I want to install Firebase pods. I got error link below I mention.

After Executing the commas “pod install”. I got the below error. Can someone please explain it to me? and how to fix it?

[!] Automatically assigning platform ios with version 14.2 on target TryFireBase because no platform was specified. Please specify a platform for this target in your Podfile. See https://guides.cocoapods.org/syntax/podfile.html#platform .

My podfile looks like:

# Uncomment the next line to define a global platform for your project
# platform :ios, ‘9.0’
target ‘TryFireBase’ do
# Comment the next line if you don’t want to use dynamic frameworks
use_frameworks!
# Pods for TryFireBase
pod ‘Firebase/Auth’
pod ‘Firebase/Firestore’
pod ‘Firebase/Storage’
end

Its fine it just because the ios version was commented out in your podfile (anything after # is commented out) so it automatically assigned the latesf ios version
