With the Screenshot that you have attached for errors & provisioning profile, looks like the problem is with the "Case Sensitive" name.
Profile : com.slogangen.slogangen
Error : com.slogangen.SloganGen
From apple documentation:
Typically, the bundle ID in your Xcode project is a string formatted as a reverse-domain name such as com.MyCompany.MyProductName, where you replace MyCompanyName and MyProductName with your domain and product name. However, unlike domain names, app IDs and bundle IDs are case sensitive.
Hope that helps.
