I'm using a beta of Xcode 9. I've archived my iOS Project and whenever I try to validate it, I get this error for every one of the targets in my app:
And I'm getting this error for every target like I said. The provisioning profile for each of the targets is an Xcode Managed Profile. What am I doing wrong?

You should try two options:
1) In
Developer.Apple.comcreate a distribution provisioning profile, download it, and select it. Then re-archive your project and validate. This should dismiss the error.2) If option 1 doesn't work for you, click the
Exportbutton beside archive and save your.appfile to your Desktop. Then openApplication Loader(In Xcode, click Xcode > Open Developer Tool > Application Loader). Enter your credentials, then upload the app using the .app file you generated and saved to your Desktop.Note: Sometimes Xcode shows fake errors when validating and
Application Loaderwill ignore those and allow you to upload a build successfully.When
Application Loaderis finished, you should then be able to see your build in iTunesConnect after about 15-30 minutes.
