Folks, looks like there’s an active pull request for the fix for this, but fb is disowning instruments-without-delay and recommending that someone just forks the project. I have tried the fix and it works, but it’s a bit hairy since new permissions issues in Xcode 7 require some plist editing to work.

Source:

I took notes of my steps to implement it the fix:

`
cd ~
git clone https://github.com/lawrencelomax/instruments-without-delay.git
cd instruments-without-delay/
git checkout xcode7-quirks
./build.sh
`

Next, you’re going to want to edit the plist file at:  
**/Applications/Xcode-7.0.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/Developer/Library/LaunchDaemons/com.apple.instruments.deviceservice.plist**

And replace it with the one from the url below. **Be sure to replace the paths ("/Users/lawrencelomax/src") with your own build dirs**:
