I'm new in iOS development and want to create an app with some charts. I decided to start development with swift because it seemed to be more easy to learn for me as Java developer. But meanwhile I think using objective-c would have been the better choice because AFAIK there is no chart library available that match my criteria:
As noted in the comments on the linked Core Plot issue, you can use Core Plot in Swift as long as you use the code from the
release-2.0 branch. The changes on that branch resolve the issues with
NSDecimal that 1.x versions of Core Plot have.
