version

Minor improvements, icons supports, Swift 3.1

supports icon for PieChart but it does not draw images on a good position regard to the related value label. it has an iconOffset with x and y but it won't fully support for all different values.

The first question seems too generic and the answer you should already know. The real issue should be your second qestion, It's better can can explain with details for

but it does not draw images on a good position regard to the related value label. it has an iconOffset with x and y but it won't fully support for all different values.

If it's a bug or need enhancements so we can take a look.

at first I didn't know about the feature of having icon in your new version, but then I realize that there is a parameter for DataEntry that receive an NSUIIMage. but it will place the image in side the pie chart.
But what i need for my project is to have the image beside the labels (see the image above -> 5%).

I found that the icon has an offset property, which will receive x and y for moving the image, but It does not handle the overlaying of images. I mean if use this icon you provide in your new version and moving it to outside the pie chart, it will overlay with other images and labels.

can you please fix this issue to handle this? or maybe you need a Bool to determine image should be outside the piechart or inside the piechart.

I have also posted a question in stackOverFlow which you can track here

I cannot find any reference in the wiki on how to do this?

@sashalondon yes , still not merged with the origin repo, but I have created the pull request which is waiting to be merge. although you can find my commits in my pull request

about how to do this:
you have to pass UIImageView to the PieChartDataEntry init class, which the name is imageView not the icon.
for example :

for i in 0..<dataPoints.count {
    let dataEntry = PieChartDataEntry(value: values[i], label: dataPoints[i], icon: nil, data: dataPoints as AnyObject, imageView: UIImageView()) //your imageView to be shown for each dataEntry
     dataEntries.append(dataEntry)
}
