Build extremely slow after upgrade to Xcode 12

After upgraded to Xcode 12, the build progress will last for about 10 minutes when the target is a real device. But it's only need less then 1 minutes in Xcode 11 with the same project and the same device.

When i check the build log, i found the signing progress cost a lot of time

I found there is 'replacing sign' in the log. So it can be caused by duplicated sign.

And then remove Pods directory and reinstall all pods via pod install. Then build speed is normal.
