Do you mean limit lines? There is an addLimitLine(_:) method on the 3 axes (leftAxis, rightAxis, and xAxis) so you can do something like this:

let lowLimitLine = ChartLimitLine(limit: 100, label: "Low Threshold")
lowLimitLine.lineWidth = 1.0
lowLimitLine.lineDashLengths = [1, 2]
lowLimitLine.lineColor = UIColor.lightGray
lowLimitLine.valueTextColor = UIColor.lightGray
    
leftAxis.addLimitLine(lowLimitLine)

That will produce something like this:

You can add as many limit lines as you like as far as I know! See also the first example in ChartsDemo.

I already knew about limit lines and I am using that also in my app. What I want is something like this in the below pic :

I want to add 4 colours to the background of the chart. The colour zones depend on the y values.

grid color stripe is not supported yet. However, you can add your own methods in drawExtra() or override some methods, to draw color grid. You can refer how the limit line/grid line is drawn, and you would know the coordinates to draw your rect then.
