I get the error: xcrun: error: unable to find utility “instruments”, not a developer tool or in path when I try to run the program below:

react-native run-ios

The error appears the system notifies as follows:

Found Xcode project TestProject.xcodeproj
 xcrun: error: unable to find utility "instruments", not a developer 
 tool or in PATH
 
 Command failed: xcrun instruments -s
 xcrun: error: unable to find utility "instruments", not a developer 
 tool or in PATH

I tried to solve it with another sample. I got the reference in the community forum, but it still returned an invalid result. If someone knows the solution, please give me the support. Thanks!

    The cause: This error appears because of  the place of Command line tools.

    Solution: You can resolve this error by doing the following process:

    1. In your Xcode, choose Xcode menu.
    2. When Xcode menu open, select Preferences.
    3. After that choose Locations tab.
    4.  Finally from the dropdown, let’s choose Xcode version and get out of Xcode.

  2. You might need to install the Command Line Tools or change its location.

    Via command line

    To set the path, you will need Xcode installed. 

    sudo xcode-select -s /Applications/Xcode.app

    You may have to install the command-line tools first if they aren’t installed. 

    xcode-select --install

    Before installing command-line tools, you may be required to accept the Xcode licence. 

    sudo xcodebuild -license accept

    Via Xcode

    You can also adjust the Command Line Tools setting using Xcode (Xcode > Preferences > Locations).
