Injection app not responding

[JonLz]

Thanks for the great tool, looking forward to trying it out!

I am trying to get the Injection app (downloaded from http://johnholdsworth.com/Injection9.app.zip) running with Xcode Version 9.0 (9A235). When trying to inject source, the Injection app stops responding.

Steps to repro:

• Run Injection app and install privileged helper
• Created a new Xcode project
• Build and run the project with a simulator open
• Try Inject Source via clicking in the menu item in the Injection app
• Injection app stops responding

Is there some setup step that I am missing? Any tips on how to troubleshoot this? Is there a console log outside of Xcode I can view somewhere? I also tried it with adding an injection function into my code but I don't think this is the issue as the app doesn't seem to be responding at all.

Thank you!

Have you firce-quit and restarted it? This can happen sometimes.

Restarted the app and the OS a few times and it seems to be working now. Now I'm seeing a new problem. Let me know if you would like this as a new issue.

Following the same steps as the initial comment, I'm seeing the below crash when trying to click on Inject Source

The first problem is caused by the second which is the InjectionApp crashing. I can TeamView if you want to try to work out whats going on. Send your ID to injection at johnholdsworth.com if interested.
