Split native targeting rule support for semantic versioning comparisons

This relates to setting up split targeting rules around app versions (necessary for mobile iOS/Android apps).

Right now, split targeting rules only allow greater/less than operations on integers. We are able to get around this by converting the app semantic version (in format MAJOR.MINOR.PATCH - https://semver.org) to an integer. We do this like so:

MAJOR*1,000,000 + MINOR*1,000 + PATCH*1 = APP_VERSION

e.g. an app version of 2.12.45 becomes 2*1,000,000 + 12*1,000 + 45*1 = 2012045

It would be great if there was some native support in the split.io targeting rules interface to treat client app versions in a more natural way.

Hi Dean,

From our end, we'd recommend you do version matching by using regex/matching matchers. We wrote a blog post about this topic a while ago:

Let us know this doesn't solve your needs!

Regards,

Hey Kevin, appreciate the reply!

The way you mentioned is likely not a realistic option for us for two reasons:
1. Non-engineers would definitely not be able to set these up
2. High risk of human error
3. Human readability is low, difficult to visually parse what version information is being checked
If there was a product solution it would simplify the user facing configuration and remove the risk of human error.

Thanks!

Hi

We are facing the same issue so even if there is possible workarounds it would make things a lot more stream lined if we would get semantic versioning comparisons.
