Time profiler in instruments is not working
提问by Carusd Ray
I recently update my Xcode to version 9.3, so is instruments. After that, time profiler won't work anymore, it usually works fine before.
我最近将我的 Xcode 更新到了 9.3 版，仪器也是如此。在那之后，时间分析器将不再工作，它之前通常可以正常工作。
I tried to run it via Xcode, and I tried to run it manually. Doesn't work. The life cycle row stuck in initializing, and I got a bunch of warnings complain about the data volume is too high for a recording mode of "immediate" and some data had to be dropped to move forward.
我尝试通过 Xcode 运行它，并尝试手动运行它。不起作用。生命周期行卡在初始化中，我收到一堆警告，抱怨数据量对于“立即”记录模式来说太高，不得不丢弃一些数据才能继续前进。
Then I switch to delay mode, still got nothing. Then I create a simple new project, which should have "little data volume", still got nothing.
然后我切换到延迟模式，仍然一无所获。然后我创建了一个简单的新项目，它应该是“数据量很小”，但仍然没有任何结果。
I checked help, I googled, seems like no one has encountered this before. Does anyone have any clue about this?
我查了帮助，我用谷歌搜索，似乎以前没有人遇到过这种情况。有没有人对此有任何线索？

I had two versions of Xcode installed, and was experiencing this when using the Instruments associated with the oldest version of Xcode (9.4.1).
我安装了两个版本的 Xcode，并且在使用与最旧版本的 Xcode (9.4.1) 相关联的仪器时遇到了这个问题。
I solved the issue by using the Instruments associated with the newest version of Xcode I had installed (10.0)
我通过使用与我安装的最新版本 Xcode (10.0) 相关联的 Instruments 解决了这个问题
