Charts/Source/Charts/Renderers/BarChartRenderer.swift:620:121: Type 'NSAttributedStringKey' (aka 'NSString') has no member 'font'

Having the same issue, just updated to Xcode 9, running Charts version 3.0.4.

[GerardoMR]

Ok, so the issue happens because NSAttributedStringKey was introduced in Swift 4 for a more convenient handling of the attribute keys.

I was using Swift 3.2, but after updating my application, all the problems went away.

Change Swift Language Version to Swift 4.0

Is there any alternative to not update to swift 4.0?

[NadyaCherniavskaya]

Had the same issue. Fixed by using an older version of Charts.

[liuxuan30]

any one who uses 3.0.4 must use Swift 4. If there are any frameworks requires lower, you should roll back chart or upgrade those old frameworks.
