RxExample-The app crashes when building iOS.

keisukeYamagishi commented 4 years ago

It's probably a bug.

Short description of the issue: When I build 'RxExample-iOS' and launch the app, the app crashes.

Expected outcome:

Being able to build an app and launch it without crashing the app

What actually happens:

When I build 'RxExample-iOS' and launch the app, the app crashes.

Self contained code example that reproduces the issue:

When RxExample-iOS build and launch Logs are listed below

dyld: Library not loaded: @rpath/RxCocoa.framework/RxCocoa
  Referenced from: /private/var/containers/Bundle/Application/35E29B7E-8EC5-41AE-AE74-F339DFFBEED0/RxExample-iOS.app/RxExample-iOS
  Reason: image not found
Message from debugger: Terminated due to signal 6

RxSwift/RxCocoa/RxBlocking/RxTest version/commit

5.1.1(The latest version of the master branch)

Platform/Environment

[x] iOS
[ ] macOS
[ ] tvOS
[ ] watchOS
[ ] playgrounds

How easy is to reproduce? (chances of successful reproduce after running the self contained code)

[x] easy, 100% repro
[ ] sometimes, 10%-100%
[ ] hard, 2% - 10%
[ ] extremely hard, %0 - 2%

Xcode version:

 Version 11.6 (11E708)

Installation method:

[ ] CocoaPods
[ ] Carthage
[ ] Git submodules
[x] git clone (Added.)

I have multiple versions of Xcode installed: (so we can know if this is a potential cause of your issue)

[ ] yes (which ones)
[x] no

Level of RxSwift knowledge: (this is so we can understand your level of knowledge and formulate the response in an appropriate manner)

[ ] just starting
[x] I have a small code base
[ ] I have a significant code base

Note

This event is occurring only on the actual device of iPhone. The devices i have checked are OS version: 13.5.1 Device: iPhone 7

A similar issue already exists, but only on an actual device. I think that should be fixed How about this?

Thanks! Can you provide a crash report or direct the place of the crash?

freak4pc commented 4 years ago

Hey @keisukeYamagishi I've tried this with a couple of friends and everything works fine for me and the other testers I've asked to check this.

That error seems related to some kind of bad Derived Data, please clean that folder and try again.

keisukeYamagishi commented 4 years ago

Thank you for response @freak4pc I've cleaned and tried it, but it still seems to cannot launch

keisukeYamagishi commented 4 years ago

Hi @freak4pc Shouldn't it be reopened? You haven't done enough testing.

freak4pc commented 4 years ago

Did you remove the entirety of your derived data folder ?

There isn't much that can be done here so I'm not sure there's a reason to reopen:

It doesn't crash for other user I've asked to check (well over 10 by now)
The crash you're having is not in the code itself but early in the launch of the app
The stack only includes dyld (dynamic loader) along with the error message saying that RxCocoa cannot by dynamically loaded, that sounds like some local configuration issue or bad local cache.

I'd be really happy to help some more but it doesn't seem to be anything reproducible I can look at, unfortunately.

keisukeYamagishi commented 4 years ago

@freak4pc Really? You cannot reproduce?

My procedure for reproducing it is to clone it from github and use When I build with Xcode 12.0 and install it on my iPhone 7 (13.5.1), it fails to start and crashes. I removed the entirety of my derived data folder But I am reproduce it The fact that you can't launch it on a device is a problem. If you can't clone it and build it and start it up in the first place, I think it's not a good situation

This problem isn`t only me , it is all user's problem

freak4pc commented 4 years ago

Does it launch for you on a simulator ?

keisukeYamagishi commented 4 years ago

Yes Simulator can build and launch

quanffq commented 2 years ago

I also encountered this problem。Is there a solution？ I imported rxswift through cocoapods and the app crashed. Works fine if rxswift is removed。

ReactiveX / RxSwift

RxExample-The app crashes when building iOS. #2222

It's probably a bug.
