Charts with swift

P

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:

usable with swift
has line and bar charts
ability to draw charts with date and time axis
free to use or low price < 100 USD

Common chart libraries like JBChartView, ~~Core-Plot~~ and iOSPlot do not fulfill my criteria so I'm thinking about either to use a JavaScript chart library in a WebView or switching completely to objective-c

Is it good practice to use a JavaScript chart API in a WebView? If so, may this make problems on different devices with different screen sizes and orientations? What are common pitfalls with this approach?

Edit: Core-Plot release-2.0 works well with Swift

I think it's pretty clunky using JS and UIWebView - avoid IMHO. What's wrong with core plot? – Assuming 16/3, 2015 at 13:11

@Assuming Core-Plot seems not be usable with swift because of incompatible datatypes github.com/core-plot/core-plot/issues/96 – Polky 16/3, 2015 at 14:3

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.

I already tried to use the release-2.0 version and thought there are still problems with NSDecimal in CPTPlotRange.length, but after trying it again it turned out that it works perfectly! So core-plot works great with Swift but this little difficulties has taught me to better switch to Objective-C because it is a more proved technology and especially for me as iOS beginner its important that there is much more documentation available. – Polky 17/3, 2015 at 9:45

You could use iOS-Charts

This is a great chart library written in swift and is on github:

There are some great tutorials going through the basics here.

iOS-Charts seems to fit your criteria

It is completely free
It is written specifically for Swift
It has 8 different graph types
