I get conflicting provisioning settings error when I try to archive to submit an iOS app

I had this same error, but I had already checked "Automatically manage signing".

The solution was to uncheck it, then check it again and reselect the Team. Xcode then fixed whatever was causing the issue on its own.

I had the same problem, I noticed that If you want to make a release of your iOs app and publish it on the App Store you don't need at all to put in the "Code Signing Identity" as release, just keep it as iOs developer.

Go to Your project -> Build Settings -> Code Signing Identity and put everything to iOs developer.

For those coming from Ionic or Cordova, you can try the following:

Open the file yourproject/platforms/ios/cordova/build-release.xcconfig and change from this:

CODE_SIGN_IDENTITY = iPhone Distribution
CODE_SIGN_IDENTITY[sdk=iphoneos*] = iPhone Distribution

into this:

CODE_SIGN_IDENTITY = iPhone Developer
CODE_SIGN_IDENTITY[sdk=iphoneos*] = iPhone Developer

and try to run the ios cordova build ios --release again to compile a release build.
