Cocoapods downloads 5.0.0 instead of the latest

[kmspop]

Hi.

I'm on Xcode 12 + Swift 5
Adding this line to my Podfile

pod 'SwiftEventBus', :tag => '5.1.0', :git => 'https://github.com/cesarferreira/SwiftEventBus.git'

downloads 5.0.0 instead of 5.1.0.

Update all pods
Updating local specs repositories
Analyzing dependencies
Pre-downloading: `SwiftEventBus` from `https://github.com/cesarferreira/SwiftEventBus.git`, tag `5.1.0`
Downloading dependencies
Installing SwiftEventBus 5.0.0

I see the Podspec is set to 5.0.0.
Would that be the reason it pulls 5.0.0?
Sorry I'm new to iOS development.
