Xcode 11 not updating changes in new build in real device

Have you ever tried building and running your app to device, but your app opens without changes?

It has a workaround but that’s very annoying. You can delete your app in your device and make another build.

But I found out what causes this problem.

Actually it is because your device has more than one developer certificate approved.

The apps with the firstly approved certificate will work just fine, but the second or later ones will experience this problem.

The better workaround is to delete the first developer certificate so that the second one will work.
