Error: cannot use instance member '_viewPortHandler' within property initializer; property initializers run before 'self' is available

[castus]

After update I have two error during compiling. Please see info below.

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

Update pod to Charts 3.1.1 (was 3.0.3)

What did you expect to happen?

It will compile as before ;)

What happened instead?

Two errors during compilation:

1. Error:(75, 76) cannot use instance member '_viewPortHandler' within property initializer; property initializers run before 'self' is available in BarLineChartViewBase.swift
2. Error:(611, 121) type 'NSAttributedStringKey' (aka 'NSString') has no member 'font' in BarChartRenderer.swift

🤦‍♂️ Now I see, thanks.

But, don't you think that versioning is wrong?
3.0.4 was a first release with Swift 4 which was backwards-uncompatible. In my opinion it should be 3.1 then. I had ~> 3.0.3 in my podfile so it should work up to 3.1, but after an update the project stops to compile.
What do you think?

We don't provide support for legacy swift. I tried on my side, changing to Swift 3.3 won't compile as well, the same errors you are facing. So if you think it should compile, report to Apple.
