使用＆＃39; Time Profiler＆＃39;时BLANK Instruments屏幕。最新版本的Xcode 6

Question

几天前，＆＃39; time profiler＆＃39;停止工作。其他乐器仍然有效...核心动画，分配等。时间分析器只是一个空白屏幕。没有显示函数调用，没有图表，没有。多个项目的结果相同。

我刚刚重新安装了Xcode（自身）。同样的问题。我无法找到任何可以删除仪器的偏好文件。我真的，真的需要这个工作。我没有时间重新安装整个操作系统。

HELP

修改：删除com.apple.dt.instruments.plist并不会改变任何内容。在仪器的控制台中找到这些日志（如下）。看起来有趣的事情正在发生，并且可能值得向Apple提交一个错误。目前，问题是 - 如何将仪器的状态重置为应该的状态？

Will attempt to recover by breaking constraint 
<NSAutoresizingMaskLayoutConstraint:0x61000009f7c0 h=-&- v=--& H:[NSSlider:0x6180001435a0]-(34)-|   (Names: '|':NSView:0x610000136760 )>

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens.  And/or, break on objc_exception_throw to catch this in the debugger.
