Gradient fill is not working for bar chart in iOS

[sathishchinniah]

let column = cartesian.column(data: barData)
let palette = ["#42aade","#236ba0","#14245a"]
column.fill(keys: palette, angle: 90, mode: true, opacity: 1)

This gradient fill is not working in iOS , it just showing the first color ("#42aade") alone. But in android it's working fine.

Tried in both 1.0.3, 1.0.4 pod versions
