Feature: Add option to draw limit lines on top of data

[siltrifork]

Is there any chance that the existing Android feature "drawGridlinesBehindData" is coming to the Swift library as well? https://github.com/PhilJay/MPAndroidChart/pull/3451/files

drawLimitLinesBehindDataEnabled

No, that feature doesn't do what I want. I want the grid lines above the data like asked here:
PhilJay/MPAndroidChart#3446

What exactly lines are you asking? You are asking limit lines and I told you use drawLimitLinesBehindDataEnabled

if you are asking grid lines, we currently don't; but you can easily do that by following how drawLimitLinesBehindDataEnabled is done, and maybe file a PR for us.
