I tried all the possible solutions in the SO, but none of them giving legit solution. Can anyone figure what's the root cause of this error ? Is the problem with iPhone or Xcode or Keychain ?

Error in Debug mode in Xcode 11 targeted iPhone SE:

Could not launch "My App xyz" has denied the launch request. Internal launch error: process launch failed: Unspecified

Open your target -> Signing and Capabilities->Set your development certificate

In my case i was using distribution profile instead of development one.

For the iPhone software version 13.5, I had to trust the Developer App from the Device Management

Settings > General > Device Management > Select the Apple Development Account you want to Trust

Clear project -> Unplug iPhone -> Restart Xcode -> Plug iPhone again helped me as well.

Xcode 11.1 (11A1027) & iPhone 7 iOS 13.1.3

You can make it work either with manual or automatic signing, you just need to disable "Debug executable" on your Xcode build scheme:
