I haven't tested beta4 yet, this may be related to #468

When Xcode12 hits GM I will look into this and #468 further.

libimobiledevice/libimobiledevice#1004 (comment)

The problem is that the com.apple.debugserver service is no longer present as of Xcode 12 beta 4. The libimobiledevice code needs to use com.apple.debugserver.DVTSecureSocketProxy instead. (But it also needs to be smart enough to know which service to use, if you want to stay compatible with older iOS/Xcode versions. It seems that the "new" name also works with iOS 13, but I don't know how far back support for it goes.)

[albertdai]

The workaround/fix in libimobiledevice side could be replacing the service name com.apple.debugserver.DVTSecureSocketProxy and removing one line about SSL disable. See details in libimobiledevice/libimobiledevice#1004.

But I could confirm that only replacing the service name in ios-deploy could not fix the issue. May need more change same as the line about SSL in libimobiledevice

Seems like https://github.com/libimobiledevice/libimobiledevice/pull/1012/files was a working solution for libimobiledevice. @gabebear would you be able to map it to ios-deploy?

I took an initial look into this and I don't think that fix will map over to ios-deploy because that fix looks like it is done at a layer below where ios-deploy operates i.e. configuring and enabling SSL is done at the MobileDevice framework level.

ios-deploy might be able to drop down to that level to create and configure the connection to the device with SSL by following what other third_party tools do but i think the MobileDevice framework might already do this. I spent some time this morning into looking MobileDevice to see if there's something we're missing that tells it to establish an SSL connection with the device. Will look further in the next couple of days.

Been referencing this reimplementation of the framework: https://github.com/samdmarshall/SDMMobileDevice/blob/c3e1e97b1310c7a7a10f68281752760038b75e16/Framework/src/SDMMD_Connection.c#L194

I created an pull request that should work. It would be nice to get some feedback if it also works for others.
