使用'時間分析器'時的BLANK儀器屏幕。最新版本的Xcode 6

Question

幾天前，'時間剖析器'停止工作。其他樂器仍然有效......核心動畫，分配等時間分析器只是一個空白屏幕。沒有函數調用顯示，沒有圖形，什麼都沒有。多個項目的結果相同。

我剛剛重新安裝Xcode（本身）。同樣的問題。我無法找到任何可以刪除樂器的偏好文件。我真的很需要這個工作。我沒有時間重新安裝整個操作系統。

HELP

編輯：刪除com.apple.dt.instruments.plist不會改變任何東西。從儀器（下）中找到這些日誌在控制檯。看起來像是有趣的事情發生，並且可能值得向蘋果提交一個bug。現在，問題是 - 我該如何重新設定儀器的狀態？

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.
