Still seeing undeclared UIColor, CGFloat error with latest code

[liuxuan30]

I am trying to add the whole charts directory into my Objective-C project, so the structure is:

ThirdParty
|
ios-charts
|
classes
|
Animation, Charts, Components, Data, Filters, Renderers, Utils

What I changed the project setting:

1. enable embedded content contains swift code
2. Defines Module: YES

I also see the setting shows the $Module_name-Swift.h was set, but I don't see xcode generates it.

After I try build,

It throws lots of errors like undeclared CGFloat, UIColor, etc. I searched the closed issues, but they are not my case. My code is the latest.

What did I miss?

The files having errors:
BubbleChartDataSet.swift, BubbleChartDataEntry.swfit, BubbleChartDataEntry,swift, BubbleChartData.swift, BubbleChartRenderer.swift

Alright, I found that the BubbleChart related swift file is missing something like:

import Foundation
import CoreGraphics.CGBase
import UIKit

After I manually add them, errors gone.

Now the questions are:

Q1: chart demo code does not report any issue even without import UIKit stuff. Why? Do I have to set any flag in my objective-C project?

Q2: I see some files are using import CoreGraphics.CGBase while some are import CoreGraphics, and some are import UIKit, while some are import UIKit.UIColor

I am not sure if we should follow the small package scope principle? I am not sure if I use import UIKit.UIColor will better than import UIKit in performance perspective

Same issue here with the swift files drop method (for iOS 7 support). Had to add the imports you specified.
