Flutter error: xcodebuild: WARNING: Using the first of multiple matching destinations

I had the same problem updating Xcode. Solve just logging back into Xcode.

  1. Open Xcode
  2. Open the project’s Runner.xcworkspace file
  3. Log into Xcode at: “Signing & Capabilities” -> “All” -> “Signing”

Item 3 was my problem. When updating Xcode, I was logged out.
