[xcode] error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65

In my case, the issue was with my Xcode build scheme. When you run react-native run-ios you may see something like,

  • info Found Xcode workspace "myproject.xcworkspace"*

  • info Building (using "xcodebuild -workspace myproject.xcworkspace -configuration Debug -scheme myproject -destination id=xxxxxxxx-xxxxx-xxxxx-xxxx-xxxxxxxxx -derivedDataPath build/myproject")*


In this case, there should be a scheme named myproject in your ios configurations. The way I fixed it is,

Double clicked on myproject.xcworkspace in ios directory (to open workspace with Xcode)

Navigate into Product > Scheme > Manage Schemes...

Created a Scheme appropriately with name myproject (this name is case-sensitive)

Ran react-native run-ios in project directory
