Have the same problem

[wachunei]

Same issue here!

[taiki-t]

I had the same issue and for my case, deleting ios/build directory and re-running react-native run-ios solved.
Errors shown were something like this:

PCH was compiled with module cache path '/old_path/ios/build/ModuleCache/241WD87OSBWAM', but the path is currently 'new-path/ios/build/ModuleCache/241WD87OSBWAM'

This happened as I imported most of project files from another project.

[jamesfoxlee]

@taiki-t Thank you! Deleting ios/build fixed it.

In my case I hadn't imported files from an old project, but obviously something had gotten stale somewhere.

[hobbyexplorer]

deleting ios/build fixed it!

[amitbravo]

I changed app name and app id(bundle identifier) . since then it was crashing with react-native run-ios . by deleting ios/build fixed it !!

[Luthfiansyah]

thanks deleting ios/build fixed it.

[ODelibalta]

Deleting ios/build did not fix my issue.

[fancyboynet]

I have the same issue, and deleting ios/build did not work.

[oliviachang29]

Strangely, I get this issue but my build succeeds.

[amberv0]

Same here, deleting the ios/build does not help, at the same time, the build succeeds.

[wmonecke]

This issue happened to me once I duplicated my project. I literally copy pasted it and tried to run it. This is the error that I got.

[miguelramosfdz]

same here

[AggarwalAnkit]

I am also getting this issue. It shows build succeeded but hangs at installation. Please someone help me with this. I create a new project using react-native init project and simply ran it using react-native run-ios.

[caseybaggz]

Same here.

[rbivan]

Same for me. The build succeeds with the analyzer issues but app starts and crash in simulator. Also android app runs OK

[MorganIsBatman]

Getting the same problem trying to launch the tutorial project - Simulator launches, it looks like the app is launching in the simulator, then the app crashes. When I click the app icon on the home screen of the simulator, it launches then immediately closes.

Have tried launching it in the simulator from Xcode and it crashes too.

I see 4 logic errors relating to Yoga in Xcode:

YGNodeList.c:26:18: Access to field 'capacity' results in a dereference of a null pointer (loaded from variable 'list')

YGNodeList.c:72:22: Array access (via field 'items') results in a null pointer dereference

Yoga.c:352:3: Null pointer argument in call to memory copy function

Yoga.c:426:3: Null pointer argument in call to memory copy function

Looking at the simulator logs, the crash report contains:
Application Specific Information:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSTaggedPointerString unsignedIntValue]: unrecognized selector sent to instance 0xa313534393830327'
terminating with uncaught exception of type NSException
abort() called
CoreSimulator 338.16 - Device: iPhone 6 - Runtime: iOS 10.2 (14C89) - DeviceType: iPhone 6

[rbivan]

Temporal solution in #15762 by @cxgslegend works for me.

Use previous version of react native in init
react-native init --version 0.47.0 <projectname>

IOS app in simulator working OK

[caseybaggz]

@aashutoshjha check out the comment above by @rbivan . That worked for me and some others.

[AggarwalAnkit]

@aashutoshjha I did sudo npm start to start packager and then ran react-native run-ios and that worked for me. I don't know the reason

[aashutoshjha]

Thanks @caseybaggz @AggarwalAnkit , tried both the things. Solved the analyzer issues but it still fails:

[andreechristian]

I also got this problem. Build succeeds but immediately crash after splash screen opened. While if i run the app via XCode, it runs perfectly. :( whyyyy

[zamudpoe]

SOLUTION:
rm -rf ios/build/ModuleCache/*

@aashutoshjha I'm having the exact same issue you are, did you ever manage to solve it?

[Suraj-Tiwari]

I got a solution that might work for you

1. rm -rf ios/build
2. sudo react-native run-ios

make sure your pc has internet connectivity.

[ahmad2smile]

Please don't do

sudo react-native run-ios

Its the worst advice ever. After doing this command doesn't open simulator and dependency watcher requires sudo permissions too then if you run in normal permissions watcher errors out cause It can't access some files which had elevated privileges previously

[arshbot]

@aashutoshjha Having a similar issue as you, did you ever solve it?

The following build commands failed:

	CompileC build/Build/Intermediates.noindex/hail-react-native.build/Debug-iphonesimulator/hail-react-nativeTests.build/Objects-normal/x86_64/hail-react-nativeTests.o hail-react-nativeTests/hail-react-nativeTests.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

With the associated error message:

[aashutoshjha]

@arshbot @ChristopherSheehan01 Wasn't able to solve it by any of the above solutions. The issue if I correctly remember was due to misplaced files in folders. Had to copy the code, create a fresh new file from X-Code and paste it there.

[arshbot]

I resolved this with this comment after trying every solution under the sun.

1. delete ios/ or android/
2. react-native eject <-- this was what did it for me
3. react-native-git-upgrade
4. react-native link
5. react-native run-ios

[ersinakinci]

I had this exact same problem and found other errors buried in the log:

1. My iPhone was connected but wasn't unlocked and I didn't enter my code to trust my computer.
2. Port 8081 was blocked (in my case, because webpack-dev-server was running in the background for a totally unrelated project), so Metro Bundler couldn't launch.

Once I unlocked/trusted and killed webpack-dev-server, the error went away and the build succeeded in the simulator. Not sure whether/how my physical iPhone is relevant, perhaps port 8081 was the only blocking problem, but I did both just to be safe.

Btw, this was on a new project after having run react-native init.

[Luckygirlllll]

I have the same issue. deleting ios/build didn't help me! any other solutions?

[armaanahluwalia]

Thanks @arshbot ... your solution worked for me -
MacOS 10.11.6

[Jaafar-abusair]

try

pod update yoga
pod install

if you are using Pod

[KunalPaul]

removing the ios folder and then recreating it does the job but don't forget to do react-native link

[mustafaskyer]

i follow these steps simply And it works for me :)
1 - rm -rf node_modules/
2 - yarn install
3 - react-native link
4 - cd ios && pod install
5 - cd .. && react-native run-ios
