[fr0l]

When trying to set location using command

fbsimctl D2AFF37C-80DE-4681-8C1B-7DA7C6123E46 set_location 40.1 20.4

then get error

remote object does not recognize selector: 'accessibilityEnabled

Here is full stacktrace:

Did quick analysis of class-dump

class-dump --sdk-ios /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sd /Applications/Xcode-beta.app/Contents/Developer/Applications/Simulator.app/Contents/Resources/Platforms/iphoneos/usr/libexec/SimulatorBridge

and I see that property accessibilityEnabled was removed from SimulatorBridge (see full diff lower)

Although I did apply temporary workaround for the issue — commented out one check in FBSimulatorBridge.m

#pragma mark Interacting with the Simulator

- (FBFuture<NSNull *> *)enableAccessibility
{
  return [[self
    interactWithBridge]
    onQueue:self.workQueue fmap:^(SimulatorBridge *bridge) {
      // Set the Bridge to a good state.

      [bridge enableAccessibility];
//      if (![bridge accessibilityEnabled]) {
//        return [[FBSimulatorError
//          describeFormat:@"Could not enable accessibility for bridge '%@'", bridge]
//          failFuture];
//      }
      return [FBFuture futureWithResult:NSNull.null];
    }];
}

@fr0l hi, did you manage to solve this?
