I encountered the \"This app could not be installed at this time\" error. I have tried several methods such as reloading the simulator, deleting the app in the simulator and
XCode: 11.3.1 Cocoapods: 1.9.1
None the previous solutions worked for me.
This should be related to the pod info.plist file setting. You might want to select Pods directory in the navigation panel of XCode and then set the info list files for each pod framework.

If there's anything goes wrong with this, there will be a button to choose the info.plist file.
Just click on that button and navigate to the bottom of the Pods directory from popup file dialog, and select your project’s pods-info.plist file.
It will automatically assign the correct identity for that pods framework like you see in the above image. This will solve the problem.
