6.0.0 version is not available via cocoapods

Hi there! At first, just want to say the library is just amazing.

Seems latest version is not available via cocoapods, currently using 5.2.1

```
[!] CocoaPods could not find compatible versions for pod "SwiftCLI":
  In Podfile:
    SwiftCLI (~> 6.0.0)
```
