如何传递类型参数并与对象类型进行比较

Question

I an learning the generic portion of Swift, and want to implement something like get a object according to the parameter.

The code seems like:

public func getChartRenderer(classType: anyClass) -> ChartDataRendererBase?
{
    for renderer in _renderers
    {
        if renderer.dynamicType is anyClass
        {
            return renderer
        }
    }

    return nil
}

This is how I call it:

let rendererType = LineChartRenderer.self
if let lineChartRenderer = renderer.getChartRenderer(rendererType) {
    // do something
}

But I never get it work... I certainly misunderstood something, but I tried google, but still not clear how to do it. Thank in advance

Use isKindOfClass

public func getChartRenderer(classType: AnyClass) -> ChartDataRendererBase?
{
    for renderer in _renderers
    {
        if renderer.isKindOfClass(classType)
        {
            return renderer
        }
    }

    return nil
}
