error message

• Using Xcode 10.3 and Firebase Messaging Cloud.
• After changing provisioning profile and bundle ID, this occurs.
• This uses one year membership account and Provisioning Profile for Development.
• When using simulator, the problem doesn’t occur.
• Though I changed: Product > Scheme > Edit Scheme > Run > Executable to Ask On Launch, this didn’t work.
• Unchecking Product > Scheme > Edit Scheme > Run > Debug executable didn’t work as well.
• rm -r ~/Library/MobileDevice/Provisioning\ Profiles/. didn’t work.
• rm -r ~/Library/Developer/CoreSimulator/Devices/. didn’t work for me as well.
• Because it seems to be a issue of Provision Profile, I tried to fix. However, I couldn’t reach a solution.
• When it comes to another new project, the same error has occurred.
• The issue also occurred with another device.
• What displays in console is below:
  • The process failed to exec
  • Unable to bootstrap process with bundleID MY-APP-NAME
  • Unable to get valid task name port right for pid 635
  • The request was denied by service delegate (SBMainWorkspace) for reason: Unspecified.

If you set the team as Personal Team under the Signing & Capabilities tab and you didn't see any error there. so just one thing left.

1. go to your device Settings.
2. navigate to the General.
3. go to Device Management.
4. trust the row specified under the Developer App.
