Can't Build Xcode Project

Your maximum app ID limit has been reached. You may create up to 10 app IDs every 7 days.

• Since using a free Apple Developer account, Xcode unable to create an app ID due to exceeding the limit of 10 app IDs

Solution

Temporary Solution

1. go to Xcode project/workspace that successfully built
   xcodeproj/xcodeworkspace > Xcode Target > General > Bundle Identifier
2. copy bundle identifier
3. go to Xcode project/workspace that can't built
   xcodeproj/xcodeworkspace > Xcode Target > General > Bundle Identifier
4. paste it in to current Xcode project/workspace that you have to built to change app ID
5. build

Permanent Solution

Just wait 7 days...
