Non-ASCII character in app name causes crash in +[NSBundle bundleWithIdentifier:]

[burkaslarry]

I use firebase firestore to develop . In this morning , no crash

as night, it gives exception at [NSBundle bundleWithIdentifier:@“org.cocoapods.grpcpp”] as screenshot stated . I have no clue on my pod settings or code... Would you please tell me what to fix?

Below is my screen shot :

Below is my code :

    Auth.auth().signInAnonymously() { (result , error) in
        guard let authResult = result else {
            return
        }
        let user = authResult.user
        let isAnonymous = user.isAnonymous  // true
        if(isAnonymous){
            let uid = user.uid
            User.shared.userId = uid
            print("user id : \(User.shared.userId)")
           self.writeProgressInitial()

        }
        // Do any additional setup after loading the view.
    }




   func writeProgressInitial() {
        let db = Firestore.firestore()
        let userRef = db.collection("user").document(User.shared.userId)
        userRef.getDocument { (querySnapshot, err) in
        if let err = err {
            print("Error getting documents: \(err)")
        } else {
            if (querySnapshot?.get("progress") == nil) {
                   var  dataDict : Dictionary<String , Any> = [:]
                   dataDict["progress"]  = 0
                   userRef.setData(dataDict)
                }else{
                    let dict = querySnapshot?.data()
                    let sssresult = dict!.filter{ $0.key == "progress" }.first?.value as? Int ?? 0
                    User.shared.progress = sssresult
                }
            }
        }
    }

Personally, I have tested that even using Dispatch async to update the progress but it fails .

@burkaslarry can you share the full stack trace of the crash? You can print the stack trace in the debugger by running bt all.

[wilhuff]

Also, there's some logging we have in this area that may help narrow down possible causes. Could you enable debug logging and post the output?

[google-oss-bot]

Hey @burkaslarry. We need more information to resolve this issue but there hasn't been an update in 7 days. I'm marking the issue as stale and if there are no new updates in the next 3 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[google-oss-bot]

Since there haven't been any recent updates here, I am going to close this issue.

@burkaslarry if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

I have same problem when my app name is chinese, once I change app name to english then it work fine, how can i fix it?

It work fine when I use Firestore 5.9.0, but crash when I upgrade to 6.11.0.

[morganchen12]

@flyingbacon can you share the full stack trace of the crash and debug logs mentioned above?

@flyingbacon can you also share the debug logs mentioned in this comment: #3951 (comment)

[flyingbacon]

@morganchen12
is there anything i can help?

i only got this log after i enable debug logging
after enable logging.txt

[mikelehen]

@flyingbacon Based on the callstack it looks like the crash is actually happening in iOS CoreFoundation code, not in Firestore, which would be pretty strange. As a sanity-check, can you just call [NSBundle bundleWithIdentifier:@"org.cocoapods.grpcpp"]; directly from your code and see if it works?

Also, just to confirm, the problem only happens if you have Chinese characters in the app name? Can you provide an example of a problematic name and how you are setting it (i.e. Packaging > Product Name under the Target settings in XCode? Or something else?). I can try to reproduce and see what happens. Thanks!

I call [NSBundle bundleWithIdentifier:@"org.cocoapods.grpcpp"]; like the image show, and it work fine.

About the app name with chinese characters, this is how I setting it
Packaging > Target > Display Name
chinese : 中文 (crash)
english : English (work)

and the problem just happen with project using latest version firebase, my old project with version 5.9.0 just fine.

maybe you can give me some suggestion to downgrade?
thx

[mikelehen]

Thanks! Unfortunately I wasn't able to reproduce this myself. But I also couldn't figure out where to find Packaging > Target > Display Name so this is what I changed:

That did change the name of the app as it appears in the Home Screen and the app switcher, but maybe it's different than what you're doing?

maybe you can give me some suggestion to downgrade?

I think you can just change your Podfile to specify the version you want to use, e.g.:

  pod 'Firebase/Firestore', '5.9.0'

Does that work?

there is no different than what I done.
maybe just xcode's problem, and no one can figure it out.

maybe you can give me some suggestion to downgrade?

  pod 'Firebase/Firestore', '5.9.0'

Does that work?

I will try it later
thanks a lot.

[mikelehen]

OK. If you keep having issues or are able to come up with a way for us to reproduce it, please let us know.

[rolfb]

Seeing the exact same issue with app name containing the letter "Ø".

[mikelehen]

@rolfb Thanks! Can you provide exact instructions in order to reproduce? Or an existing project that we can just open / run?

[rolfb]

@mikelehen Fastest way to reproduce is to change the target product name of an existing app to something like Ører, clean build and build, and try to do a set() with firestore. I think you can verify that you set if correctly if the built product is called Ører.app. Failure is reproducible in simulator.

[mikelehen]

@rolfb Thank you! The tip about looking for Ører.app was helpful. It turns out I had changed the display name but not the actual app name, and it seems to be the non-ASCII characters in the filename that are causing issues.

It looks like this is most likely an Apple bug. I can reproduce the same crash by just calling Bundle(identifier:"org.cocoapods.grpcpp") directly from my code (with Firestore as a dependency). I'll try to log a bug against Apple and in the meantime we're looking into potential workarounds. I'll update here once we have more info.

[morganchen12]

Potentially related to rdar://26897226, since it's failing in bundle path validation.

[mikelehen]

I created a minimal-ish repro here and (I think?) logged a bug against Apple using their "Feedback assistant" here: https://feedbackassistant.apple.com/feedback/7454511 though I'm not sure if that's public or not.

For now, we have a possible workaround for Firestore that @var-const is working on implementing.

[rolfb]

@mikelehen that’s really great. The link wasn’t available even if I logged in with my Apple Developer ID. Appreciate the thoroughness.

[rolfb]

Manually setting CFBundleDisplayName in Info.plist –– viewed as source, not Plist –– to Ører works too.

[wilhuff]

FYI, we shipped our workaround for this issue as a part of FirebaseFirestore 1.8.1.
