App Installation Failed! Unrecognized Status

My app has no errors when built. I connected my phone to test the Swift app, which had previously been working consistently on my phone. But this time, it stated that the app failed to install. After hours of going through my code and fixing all possible errors, this issue is extremely frustrating. I have a free developer account, but I'm only testing one app. I tested with my phone on my iMac, and it didn't work. So, I took a friends phone and tested it on a DIFFERENT mac with the same version of Xcode and the problem was here too! I deleted derived data, restarted computer and phone multiple times, and cleaned and rebuilt project multiple times already. I deleted the app from my phone as well. I don't know whether this is a problem with Xcode or something that I'm doing.


I get an error which states "unrecognized status -67030 from codesigning library".


At this point, I'm extremely frustrated and would greatly appreciate a solution.


Thanks
