I've been developing an app over the last 8 or 9 months with a decent degree of success. However, I had to step away from the project for about 6 weeks. When I came back, I realized I could not get my mobile application to downlaod to my iPhone which I had been using as a test device (this is required because the app uses Bluetooth). I realized the issue was because I had a lot of different softwares all fighting with each other. My iPhone and Mac were both running on beta versions of their respective softwares. I tried using all three of the different Xcode betas with these operating system betas but to no avail. So I reset my iPhone and Mac to the standard release versions of their respective OSes. Still no luck, with any form of Xcode (Release or Beta).
So now I'm really stuck with the following error:
"Could not locate device support files.
This iPhone 8 Plus (Model A1864, A1897, A1898, A1899) is running iOS 12.2 (16E5181f), which may not be supported by this version of Xcode."
I'm running macOS 10.14.3 and iOS 12.2 on my iPhone 8 Plus.
I have attempted running this on Xcode 10.1 (newest release) all the way through all three betas of Xcode.
The only difference is that when I attempt to run on XCode 10.1 Beta 3, the software "runs" but displays nothing on the iPhone before I get this Xcode error:
"dyld: Symbol not found: _OBJC_CLASS_$__TtCs12_SwiftObject

Expected in: /usr/lib/swift/libswiftCore.dylib
Now I'm really lost and completely stuck on this project. It's quite infuriating. Any help would be very appreciated.
