DeveloperDiskImage.dmg for iOS 17 not found in Xcode 15

[vashworth]

As of Xcode 15 and iOS 17, DeveloperDiskImage.dmg is no longer found in the expect path, which is Xcode.app > Contents > Developer > Platforms > iPhoneOS.platform > DeviceSupport > 17.x.

This appears to be a permanent change:

Expected behavior

Debugging starts properly

Actual behavior.

Debugging phase fails due to missing DeveloperDiskImage.dmg.

------ Debug phase ------
Starting debug of xxxx (J617AP, J617AP, uknownos, unkarch, 17.0, 21A5248v) a.k.a. 'xxx' connected through USB...
2023-06-09 11:42:16.219 ios-deploy[45135:1129696] [ !! ] Unable to locate DeviceSupport directory with suffix 'DeveloperDiskImage.dmg'. This probably means you don't have Xcode installed, you will need to launch the app manually and logging output will not be shown!

Steps to reproduce the problem

1. Download Xcode 15 beta
2. Select new Xcode

xcrun xcode-select --switch /Applications/Xcode-beta.app/Contents/Developer

3. Download iOS 17 on a physical device
4. Run ios-deploy

ios-deploy --id xxxx --bundle path/to/Runner.app --app_deltas path/to/app-delta --debug --no-wifi

I'm not sure if we want to have ios-deploy work with Xcode15; it's possible Xcode14 will be the final version supported. Apple has FINALLY created a non-hack mechanism with devicectl(e.g. try running xcrun devicectl --help). https://developer.apple.com/documentation/Updates/Xcode

@gabebear Nice! Maybe worth adding to the readme 🙂

Summary of install & just launch with devicectl:

xcrun devicectl device install app --device 00008110-001XXXXXXXXXX ./xgen/Build/Products/Release-iphoneos/nilo.app
xcrun devicectl device process launch --device 00008110-001XXXXXXXXXX file:///private/var/containers/Bundle/Application/1604D2D5-35F3-4E43-8B47-1DEF5D778480/nilo.app

You get the second path from the output from the install command, or just use the bundle ID (sadly the app name isn't enough, unlike for xctrace)

Even using xcrun to install/launch there's still the issue of connecting to lldb and managing stderr/stdout. That's the majority of what I use ios-deploy for. I think that purpose is still legit in xcode15-land
unless there's a simple command for that as well that should go in the readme?

[gabebear]

Ideally Apple will add a way to connect to lldb to devicectl.

Apple tracks feedback/radar reports to gauge interest in products. People who need iOS device debugging scripting support should file requests via https://feedbackassistant.apple.com/ . This could possibly get Apple to add this before the team that created devicectl moves to other things.

xcrun devicectl device install app --device 00008110-001XXXXXXXXXX ./xgen/Build/Products/Release-iphoneos/nilo.app
crun devicectl device process launch --device 00008110-001XXXXXXXXXX file:///private/var/containers/Bundle/Application/1604D2D5-35F3-4E43-8B47-1DEF5D778480/nilo.app

Seems Apple's devicectl is not easy to use, can we wrap it under the hood after Xcode 15?

Ideally Apple will add a way to connect to lldb to devicectl.
Yep. That'd be pretty nice. With CoreDevice there are IPv6 tunnels created to each device. You can point lldb directly at one of those and connect to it. The filehandle/socket forwarder is no longer required. The trick is figuring out the port that the debugserver is running on. That seems a tad convoluted currently. Doable but convoluted. I did take your advice and submit a feedback suggestion.

xcrun devicectl device install app --device 00008110-001XXXXXXXXXX ./xgen/Build/Products/Release-iphoneos/nilo.app
xcrun devicectl device process launch --device 00008110-001XXXXXXXXXX file:///private/var/containers/Bundle/Application/1604D2D5-35F3-4E43-8B47-1DEF5D778480/nilo.app

devicectl is not as simple to use, we print some results to std::out and it seems like there is no way to capture this data like ios-deploy used to do. Also, we are stuck installing, launching, and then continuously polling the device to see if the application ran, as there is no way to attach to process launch

In addition with ios-deploy I was able to easily upload files to the bundle and it seems like with devicectl I keep getting errors
