With Xcode 11.2.1 created a single View project for iOS and enabled the Thread Sanitizer in Scheme. Note: Running the app on Simulator iPhone Xr 13.2.2

Once run the project, getting below error:

The request was denied by service delegate (SBMainWorkspace) for reason: Unspecified ("null").

Details

The request to open "kumar.helloworld" failed.
Domain: FBSOpenApplicationServiceErrorDomain
Code: 1
Failure Reason: The request was denied by service delegate (SBMainWorkspace) 
for reason: Unspecified ("null").
User Info: {
    BSErrorCodeDescription = RequestDenied;
    FBSOpenApplicationRequestID = 0x9e5a;
}
--
The operation couldn’t be completed. (null)
Domain: FBSOpenApplicationErrorDomain
Code: 1
Failure Reason: (null)
User Info: {
    BSErrorCodeDescription = Unspecified;
}

When set the executable as Ask on Launch getting the below error:

Cannot find Thread Sanitizer runtime support library. Please specify it manually by setting DYLD_INSERT_LIBRARIES environment variable.

If disabled the Thread Sanitizer, then app is launching properly in the simulator.

Any help in this case will be appreciated. Thanks!

  • Already tried **Hardware -> Erase All Content and Settings ...** on simulator, deleted the content in derived data folder, restarted Xcode and simulator but nothing helped. – sumit.kumar Nov 18 '19 at 06:05
