Setting up for macOS app dev

[hboon]

I've been able to use InjectionIII for iOS apps running on the simulator previously. However I can't figure out how to make it work for macOS apps. With and without InjectionIII running, I get something like this that mentions bazel.

InjectionClient/Could not connect: Operation not permitted
🔥 Unable to connect to InjectionIII app, falling back to standalone HotReloading.
<SwiftEval: 0x123604440>.deinit()
🔥 Standalone HotReloading available for sources under ["/Users/hboon"]

🔥 ⚠️ Locating response file failed (see: /Users/hboon/Library/Containers/com.motionobj.disksweeper/Data/tmp/command.sh)
/Users/hboon/Library/Containers/com.motionobj.disksweeper/Data/tmp/command.sh: line 2: cd: /Users/hboon/Documents/bazel-out/../external/build_bazel_rules_swift: No such file or directory

error: tools/worker/swift_runner.cc: No such file or directory

error: tools/worker/swift_runner.h: No such file or directory

I'm using the Inject package. I have tried with and without the HotReloading package. Have tried with and without running "Prepare Project". Have tried installing bazel. Have tried the Run Script phase for iOS (like described in the README). Have tried loading the bundle in code.

I use XcodeGen and not tuist, nor bazel for the project, if it matters. Have also renamed project.yml so it shouldn't accidentally trigger any checks.

Help :) 😭

Hi, Can you try turning off the sandbox?

[hboon]

Hi John! I read in the docs to turn off ENABLE_APP_SANDBOX (it's already off for me) and I also turned off ENABLED_USER_SCRIPT_SANDBOXING, but I forgot where I read about it.

Both are off for the console out above.

[johnno1962]

You're not running the app? Do you have a WORKSPACE file somewhere? You seemed to have turned on the Bazel support.

[hboon]

The output is for when the app is not running. It would say connected if it is, but still shows the same Bazel related errors. The directory (that I would choose in InjectionIII if it's running) looks like this:

I renamed the project.yml just in case. Oh, could it be buildServer.json?

[hboon]

Nope, remaining buildServer.json still triggers the same error.

[hboon]

Is there an example where it works with macOS? I found a couple for iOS which worked for me and I used to use it with iOS.

[johnno1962]

Not that I'm aware of. The best thing you could do at this stage is to create a new macOS app without sandbox and get things running and then work your way back to your app.

[hboon]

Thanks. I started a fresh project with Xcode's macOS wizard and did it step by step and got a different error below:

1. Add to OTHER_LDFLAGS:

    		OTHER_LDFLAGS = (
    			"-Xlinker",
    			"-interposable",
    		);
   

2. Add Injection package:

https://github.com/krzysztofzablocki/Inject.git

3. Run InjectionIII and choose the project directory

Run project and still nothing in the console

4. Add import Inject, @ObserveInjection var, .enableInjection()

Run project and still nothing in the console. But it complains about team and platform ID and signature

5. ENABLE_USER_SCRIPT_SANDBOXING = NO

6. Add Run Script build phase

RESOURCES=/Applications/InjectionIII.app/Contents/Resources
if [ -f "$RESOURCES/copy_bundle.sh" ]; then
"$RESOURCES/copy_bundle.sh"
fi

Complains falling back to standalone mode but wouldn't because we are using Injection

7. Add INJECTION_STANDALONE as scheme's env var

Getting:

This could be due to one of the following:
1. Injection does not work with Whole Module Optimization.
2. There are restrictions on characters allowed in paths.
3. File paths in the simulator are case sensitive.
4. The modified source file is not in the current project.
5. The source file is an XCTest that has not been run yet.
6. Xcode has removed the build logs. Edit a file and re-run.

I've verified this file exists and is non-empty: /Users/hboon/Library/Developer/Xcode/DerivedData/Foo-cjazpklsqoadreakjxbqxfoaivdf/Logs/Build/1A16774D-8E6B-4A21-8EB7-C6FA219A8E98.xcactivitylog

This path is the source file I have modified: /Users/hboon/Desktop/Foo/Foo/ContentView.swift

1. Injection does not work with Whole Module Optimization.

It's disabled

2. There are restrictions on characters allowed in paths.

Is this the source path "/Users/hboon/Desktop/Foo/Foo/ContentView.swift"? Seems OK

3. File paths in the simulator are case sensitive.

macOS, but looks OK?

4. The modified source file is not in the current project.

It is

5. The source file is an XCTest that has not been run yet.

Nope.

6. Xcode has removed the build logs. Edit a file and re-run.
   Try a build clean then rebuild to make logs available or

Tried while observing the Build/ mentioned above.

Any idea what to look for or troubleshoot? If you don't mind looking, I've pushed the repo to https://github.com/hboon/Foo (unfortunately I wasn't planning to publish this when I created it, so please excuse the dirty commits and repo name)

[johnno1962]

Can you try moving your project out of the Desktop folder. The has special permissions which sometimes cause problems.

[johnno1962]

You may be better off running the app rather than using "standalone" injection.

[hboon]

I tried again, this time with a fresh project that is somewhere in my ~/Documents/ directory. Didn't use the Injection package. But it complains that it's falling back to HotReloading and I get the bazel related error again.

InjectionClient/Could not connect: Operation not permitted

Here's what I tried:

1. Load bundle in app:

#if DEBUG
Bundle(path: "/Applications/InjectionIII.app/Contents/Resources/macOSInjection.bundle")?.load()
#endif

2. Add to OTHER_LDFLAGS:

				OTHER_LDFLAGS = (
					"-Xlinker",
					"-interposable",
				);

3. ENABLE_USER_SCRIPT_SANDBOXING = NO

4. Add Run Script build phase

RESOURCES=/Applications/InjectionIII.app/Contents/Resources
if [ -f "$RESOURCES/copy_bundle.sh" ]; then
"$RESOURCES/copy_bundle.sh"
fi

5. Modified code in step 1 to:

if let path = Bundle.main.path(forResource: "iOSInjection", ofType: "bundle") ??
                Bundle.main.path(forResource: "macOSInjection", ofType: "bundle") {
                Bundle(path: path)!.load()
            }

What does this mean:

InjectionClient/Could not connect: Operation not permitted

[johnno1962]

Can you try running the app please. That give you control over the project directory and does "fall back". Do you have an environment variable INJECTION_BASEL or a user default "bazelLight set?

[johnno1962]

InjectionClient/Could not connect: Operation not permitted

This means you still have the sandbox turned on.

[hboon]

Can you try running the app please.

The app is running. I also chose the project directory with Open Project.

InjectionClient/Could not connect: Operation not permitted

This means you still have the sandbox turned on.

I verified that ENABLE_USER_SCRIPT_SANDBOXING and ENABLE_APP_SANDBOX are off for the target, is there another option I might have missed?

Do you have an environment variable INJECTION_BASEL or a user default "bazelLight set?

I did:

$ defaults read > foo

and these returned 0 hits:

$ ag injection_ba foo
$ ag bazel foo

Not for these too:

$ echo $INJECTION_BASEL
$ echo $INJECTION_BAZEL

Not set in the scheme's env var too.

The first part of these file /Users/hboon/Library/Containers/com.motionobj.InjectionIIIOnly/Data/tmp/command.sh is puzzling perhaps? —

# search through bazel args, most recent first

[johnno1962]

If you are still seeing "Operation not permitted" instead of "Connection refused", the sandbox is still on.
