Hi which version of Xcode is this? Are you able to upload the stack trace/crash file? Can you try the new release candidate 4.7.3? https://github.com/johnno1962/InjectionIII/releases/tag/4.7.3

[y500]

yes, version of 4.7.3.

Thanks, the stack track is very useful, this is something to do with injecting a generic class in your app. Let me think about how to track this down. This is something that usually works but intermittently fails? Does this always happen injecting one particular file?

[y500]

Yes, it usually works but intermittently fails before.
But from a couple of days ago, it has become crashing so often that I almost can't use it.
And I can't figure out if that was because of injecting one particular file or not.

[johnno1962]

It would most likely be related to the file you're injecting. Let me see if there is something I can do or you could try a recent Xcode (15)?

[y500]

ok, thank u very much.

[johnno1962]

The only thing I could do at this point is a "TeamView" session to review the code being injected and see if there is anything I can do to avoid the crash. If this is possible, email your details through to github at johnholdsworth.com.

[y500]

I would like to but I can't do that, cause it is not a personal project, and thank you all the same.

[johnno1962]

I've uploaded a new release candidate https://github.com/johnno1962/InjectionIII/releases/tag/4.7.4RC2 if you'd like to try it out to see if it is more reliable. If you could get back to me a little more quickly that would help me resolve this issue.
