Pod not building on Xcode 13 Beta & iOS 15 Beta

[juliansteenbakker]

Information
I tried building this pod for a flutter plugin with the Xcode 13 Beta, however it gives a lot of errors. Seems to be something with unwrapping the service from the characteristic object. See the logs for more information.

DFU Bootloader version:

• Library version: 4.10.3

Device information:

• Device: iPad Air 2
• OS: iOS 15 Beta

Logs
(Image because full stack trace is too long for Github)

Thank you for creating the issue. I really like Apple for caring about backwards compatibility.

This seems to be because of this kind of API changes

At least its not like Android where everything gets deprecated after a new api release.. 😅
