我在使用Xcode 6 beta 6构建Swift程序时,从链接器收到一条错误消息,目标是iOS 8.这段代码在beta 5中编译并正确运行.

Undefined symbol for architecture x86_64:
__TFSs26_forceBridgeFromObjectiveCU__FTPSs9AnyObject_MQ__Q_", referenced from:
 __TFC8RayTrace14RayTracingPlot15drawFocalPointfS0_FT_T_ in RayTracingPlot.o
ld: symbol(s) not found for architecture x86_64

这是有问题的代码:

private func drawFocalPoint() {
    var attributes = Dictionary<String, AnyObject>()

    let FString: String = "F"
    let distance: CGFloat = focalDistance

    let centerX = CGRectGetMidX(bounds)
    let centerY = CGRectGetMidY(bounds)

    let circleRadius: CGFloat = 4.0
    let focalPointFrame = CGRectMake(0, 0, circleRadius * 2.0, circleRadius * 2.0)
    var path = UIBezierPath(ovalInRect: focalPointFrame)
    let color = UIColor.blackColor()

    let currentContext = …

对于在Bata 6中遇到类似问题的任何人,我通过删除/ Users/[您的用户名]/Library/Developer/Xcode/DerivedData中的内容解决了这个问题,这可以在这篇文章中看到.在Swift中突然出现编译器崩溃"arrayForceCast" XCode beta 6

我刚刚安装了Xcode beta 6,并且遇到了非常不寻常的错误.我无法弄清楚它们是什么.

我最近更新到Xcode 6 Beta 6,现在我在Beta 5中运行良好的应用程序中遇到这些错误.我一直在浏览每个方法并注释掉引起问题的行,但是还有另一个解决方案.这是日志.
