I manually deleted my app from the iPhone and now I get this error message when trying to run it again from Xcode.
I cleaned the build folder, restarted the device, Xcod
A solution that solved this issue for me was to check the signing team for my tests target. Selecting the same development team then meant that my app was able to be built and run on device.
Build system: New Build System
Xcode: Version 11.1
