Right way to add Charts with cocoapods-CodePudding

Charts suggested us to install them with cocoapods without specifying release tag: pod 'Charts' and this is means that we are working with the master / trunk branch, right? So what is about potential risks of the inability of the existing Application with the last changes in Charts? How can I add Charts with specifying the concrete version?

P.S. specifying tag neither

pod 'Charts', '4.0.1'

nor

  pod 'Charts', :git => 'https://github.com/danielgindi/Charts.git', :tag => '4.0.1'

doesn't help, and brings us the error:

% pod update
...
Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "Charts":
  In Podfile:
    Charts (= 4.0.1)

None of your spec sources contain a spec satisfying the dependency: `Charts (= 4.0.1)`.

You have either:
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Looking in GitHub, it appears that their tags have a "v" at the front of the version number. I would change your versioned attempt to be:

pod 'Charts', :git => 'https://github.com/danielgindi/Charts.git', :tag => 'v4.0.1'

Note I've changed 4.0.1 to v4.0.1 to match the tag name on GitHub.

With help of Scott Thompson, I've found that

pod 'Charts', '3.6.0'

is worked and there are no error at build time! So, I think this is the right solution.
