Can core-plot be used with Swift?

[marklivingstone]

I am wondering if anyone has successfully used core-plot with Swift yet? Are there any tutorials or sample code available?

That's probably better suited for sites like www.stackoverflow.com, not an issue tracker.

Hi Mike,

Thanks for your comment. In fact I went to www.stackoverflow.com and
searched for "core-plot swift" and found exactly one message where the OP,
after trying the answer, comments it did not work.

Since I am just starting out with both core-plot and swift, I wanted
reassurance from the core-plot devs or others whether they had tried it yet?

Cheers,

MarkL

I understand, but still this is not a question for an issue tracker. You report problems here or ask for enhancements, not to get support.

And no, I haven't heard of any user of coreplot having tried to use it with swift.

I'm working on converting one of the example apps to use Swift, but it's not done yet.

Mike's right, questions belong on StackOverflow or the discussion board.

Right now, with Xcode 6 beta 4, it's not looking easy (or maybe even possible) to use Core Plot from Swift for anything other than pie charts. The problem is a lot of methods that take NSDecimal parameters. Swift does not support bit fields in structs, which means any function or method that references NSDecimal does not get imported into Swift code. If Apple does not add support for NSDecimal in Swift, we'll need to look at redesigning the Core Plot API to accommodate this.

[eskroch]

This is still an issue with Xcode 6 beta 5. If Apple does not address this before releasing Swift 1.0, we will look into updating the Core Plot API so it can be used from Swift.

Xcode 6 beta 6 was released, does it work there? i'm hoping because I really want to use this api :)

[eskroch]

No, still no NSDecimal support in Xcode beta 6. :-(

I believe swift has NDecimalNumber, although I image there would be a performance cost associated with switching wholesale to that.

[eskroch]

Switching all of the external API methods that currently take NSDecimal numbers to NSDecimalNumber or NSNumber is one possible solution to this problem. That's a major API change that will either break a lot of existing code (the 2.0 release is a good time to do that) or require maintaining two versions of many methods for a while.

I want to wait until the Swift language reaches 1.0 before undertaking a big change like this. If Swift gains support for NSDecimalor a native decimal type bridged to NSDecimal, we won't need to make this change.

May I ask what's the progress of this issue?
We may need do some workaround for it's using swift and CorePlot ...

[eskroch]

I've done some changes to the Core Plot API to replace all external references to NSDecimal with NSNumber. This way you can still use decimals if the extra precision is needed (via NSDecimalNumber), but between NSNumber literals in Objective-C and the automatic bridging in Swift, it's much easier to use. I want to do a little more testing before I push it up to GitHub. I'm hoping to have this done by the coming weekend.
