When updating to Chart 4.1.0 Xcode can't find protocol definition for; ChartViewDelegate IChartValueFormatter

This is in old OBJ-C code

Exactly same to me. Cannot find type (IAxisValueFormatter, IValueFormatter) in scope.

• I guess if you want to solve the problem it's about removing #import bridging header of files contained in you're pods libraries..and there's another solution ( Go to build settings and build after setting Precompile Bridging Header YES -> NO. You can show no errors. But codes defined by objec aren't recognized. It is not able to jump to definition.)

Hey guys, I was confused too before I noticed that they have been renamed to (AxisValueFormatter, ValueFormatter) https://github.com/danielgindi/Charts/issues/4775#issuecomment-1026495171

@nailaobaba you are right, it works by replacing the name. Thank you.

[JorgenAndreasson]

@nailaobaba Any update to the ChartViewDelegate name?

[nailaobaba]

@JorgenAndreasson Sorry, no idea about that

I found one solution please follow:

1. pod 'Charts', '3.6.0'
2. Find below code and add code after that

extension ChartDataSet: RangeReplaceableCollection {
// add this method
        public func replaceSubrange<C>(_ subrange: Swift.Range<Index>, with newElements: C) where C : Collection, Element == C.Element {
            entries.replaceSubrange(subrange, with: newElements)
            notifyDataSetChanged()
        }

This solution works for me
