To debug a program on a device running iOS 13 you need Xcode 11. That includes Swift 5.2, and thus is incompatible with this third-party framework.
The best way forward here is to nag the third-party framework’s author to create a more up-to-date version of their framework. Now that Swift supports both binary and module stability, this new version of their framework should be able to support Swift 5.2 and all future versions of Swift. Yay!
If your nagging efforts are unsuccessful, your options are rather limited. One possibility is to build the app, export it as a
.ipa, and then install the
.ipausing the Devices and Simulators window (or iTunes). You won’t be able to debug, but you can at least run the app that way.
