There is no formal team; this is, officially, a peer support forum.

app_swift is not part of Asterisk, so this is not the place to obtain support for it.

The bad magic number errors is typically the result of memory corruption, which may have happened some time ago, or failure to use locks properly. Both can be difficult to diagnose.

Even if Asterisk didn’t crash and restart, I would advise restarting after this error, as the corruption may will be long lasting.
