Hot reloading failing on real iOS device

Adrien Baron commented a year ago

Seems like I can't get hot reloading to work on my iOS device.

Setup:

iPhone 14 Pro running iOS 16.5 (20F66)
macOS 13.4.1 (22F82) (M1 Pro)
XCode 14.3 (14E222b)

What I've done:

Downloaded and installed InjectionIII (latest version: 4.7.0).
Added this library to my new Swift project

Added the linker flags

Ran defaults write com.johnholdsworth.InjectionIII deviceUnlock any
Added an environment variable to my scheme with my computer local IP

Added the Run Script/Build Phase

I can see it being set when reading from the terminal:

➜  ~ defaults read com.johnholdsworth.InjectionIII
{
    "/Users/adrien.baron/perso/volumizer-new/Volumizer/Volumizer.xcodeproj" = 55B1F64367A6DB4244C5D555C6062DAC71AF1B7F;
    deviceInform = Informed;
    deviceUnlock = any;
    lastProject = "/Users/adrien.baron/perso/volumizer-new/Volumizer/Volumizer.xcodeproj";
    lastWatched = "/Users/adrien.baron/perso/volumizer-new/Volumizer";
}

What I'm seeing:
App starts on the phone, and connect successfully to the InjectionIII app:

It does warn about test bundles, but I don't have test for this app yet (so assuming this is unrelated).

What fails:
When I do some change to the code, the app rebuilds but complains about .dylib having invalid code signing:

Nothing I've tried so far seemed to have made any difference, but I also can't find anyone online having this issue, am I holding it wrong 😅?

Note
I sadly can't use the simulator while working as I'm using RoomPlan and it doesn't run in a simulator

Hi, getting codesigning right is difficult and the code sign (errno=1) doesn't give you much to go on.

The first thing to check is that Injection is signing correctly. Can you run the Injection app from the command line

$ /Applications/InjectionIII.app/Contents/MacOS/InjectionIII

Then look for the line 💉 InjectionIII Signing with identity: 511C1148E461780FD8B3C04906E..., check the identity is the same as for the app in the build logs and look for any error that might follow it.

@johnno1962 thank you for coming back to me that quickly! I've ran the app in a terminal and I'm getting a similar error there too. Nothing in those logs strike me as super suspicious, but I'm quite new to Swift dev 😅

It seems to sign with identity: 55B1F64367A6DB4244C5D555C6062DAC71AF1B7F

I've checked the build log and the signature do seem to match:

Feel free to ask if I can provide anything else 👍!

Thanks for the detailed reports. The next thing to try is to update the HotReloading package and replace the "Build Phase" you added with the following instead of running the InjectionIII.app:

if [ -d $SYMROOT/../../SourcePackages ]; then
    $SYMROOT/../../SourcePackages/checkouts/HotReloading/start_daemon.sh
fi

This runs the app's code but as a daemon which is easier to work on. If this doesn't work I can TeamView to investigate further. Would that be possible?

Adrien Baron · Answer 4 · Mon Jun 26 2023 17:21:27 GMT+0800 (China Standard Time)

@johnno1962 replaced the script with the code to start the daemon, and killed the InjectionIII app. Then started the app, it does start the daemon and connect, but still the same issue with dylib.

Happy to TeamView (or similar) if that can help! You can DM me on Twitter?

John Holdsworth · Answer 5 · Mon Jun 26 2023 18:06:01 GMT+0800 (China Standard Time)

Very strange problem. Using the daemon eliminated a couple of things. Could you try switching HotReloading to branch "include-entitlements" which adds the entitlements file to the code signing arguments? HotReloading uses a cache and to make sure it gets flushed remove the file /tmp/iOS_builds.plist before you start your app. You should see the new -entitlements argument in the com.johnholdsworth.InjectionIII defaults after that.

Adrien Baron · Answer 6 · Mon Jun 26 2023 21:18:28 GMT+0800 (China Standard Time)

@johnno1962 ok done this, still the same issue 😅:

I do get the entitlements flag:

    lastWatched = "/Users/adrien.baron/perso/volumizer-new/Volumizer";
}

I did delete the cache file, although it was called /tmp/maciOS_builds.plist

Here are the logs/cache I've found in /tmp (hot_reloading.log, maciOS_builds.plist and unhide_object.log).
I've cleared them, started the app, did one change and then got them. Hope this helps 🙇‍♂️!

John Holdsworth · Answer 7 · Mon Jun 26 2023 21:20:50 GMT+0800 (China Standard Time)

Still looking at this, about the only progress I've made is to replicate the code signing error=1 if you add the following to the Build phase (which stops the --entitlements "fix" being bypassed by values in the environment):

unset EXPANDED_CODE_SIGN_IDENTITY
unset CODE_SIGN_IDENTITY

Give me a little longer, I've not seen this code signing problem before. Usually it is connecting over the network that is the problem.

Adrien Baron · Answer 8 · Mon Jun 26 2023 21:34:09 GMT+0800 (China Standard Time)

@johnno1962 the code is also very new, so I'm also happy to give you access to that repo if that helps debugging 👍 (sorry should have offered that before)

EDIT: Added you, the branch is feature/inject 👍

This turned out to be a change to the default value for the PATH environment variable. This should be fixed in the 4.7.4 release.
