Updating Charts to 3.0.4 and Swift 4 doesn't work

[Wh1rlw1nd]

Hi, and thanks for this great library!

I have updated Charts to 3.0.4 version, and in Pods -> Targets -> Charts have set Swift Language version to 4.0. This is how related section looks like:

And these are errors I am seeing when I try build :

This is my Podfile :

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.2'
pod 'Charts'
use_frameworks!

project 'myProject.xcodeproj'

target 'myProject' do
  pod 'Charts'
end

and this is how Podfile.lock looks like:

PODS:
  - Charts (3.0.4):
    - Charts/Core (= 3.0.4)
  - Charts/Core (3.0.4)

DEPENDENCIES:
  - Charts

SPEC CHECKSUMS:
  Charts: 0705898046257443f0afbbc3179f4b67507b6e48

PODFILE CHECKSUM: 2550099e0fb5ee6e78531ab01d41df014f8df3c4

COCOAPODS: 1.3.1

Any idea why I am getting these errors ?

you don't use Charts 3.0 right? The method name seems 2.x style and has been removed. You should update your code then. read #1474
