Regarding to label of axis, I think it displays .03 instead of 0.03

when it has decimal places and smaller than 1.
I want it to be 0.03 or 0.15 instead of .03, .15
I couldn't find a way to handle it.

use valueFormatter....

Awesome, thank you so much.
Just put what I did at the end and hope this will help someone else has the same issue.

leftAxis.valueFormatter = DefaultAxisValueFormatter(block: { (value, _) -> String in
    //.toString() is a function I coded to convert double to string with decimal places. 
    return "\(value.toString(AppConstants.decimals))" 
})
