I am testing an app on IOS and for some reason every simulator except iPhone 5 works (my physical device is also IPhone5 and that does not work either). Anyone have an idea of why only iPhone 5 fails? (also receives a lot of warnings)
Deployment target 9.0
Xcode: Version 8.3.2 (8E2002)
I suspect it’s something to do with that device using a 32-bit processor, though theoretically this project should build for both 32- and 64-bit devices. What happens if you play with the “only active arch” flag (or related) in xcode?
I have tried different combinations, but same problem exist.
I managed to get it to work.
If I just play from xcode I always get the linking error. To get it to work with simulators (except iphone 5) I have to run this command:
Iphone 5
Physical device
This is a bit weird because “react native run-ios” is usually enough with stock react projects.
I have managed to work around this case until now that I have to run “Archive” to create a app for Appstore. Anyone have an idea of what is wriong? Are there any commands I can run to create an archive from React-native ?

I found that React is not built in Xcode when my app is detached (Regular react native apps react is build is first element). Isn´t that a problem?
Hi, can you try detaching a totally blank project and see if the issue appears there as well? I just tried this:
And it worked for me. Xcode 8.3.2, target is an iPhone 5 simulator. So I wonder if there is something else going on with your specific project.
Hi Ben
I have tried again with a new project and I am having the same issues with this project. Linking error. I have Xcode: 8.3.2. Updated to 8.3.3 with no change. Could there be some missing info in my exp.json file or something?
Created new project in expo
expo detach
Run pod install from your project’s ios directory.
Linking error.
Hmm, what version of cocoapods do you have?
Cocoapods version is 1.2.1
react-native-cli: 2.0.1
Mac 10.12.5 (Sierra)
i have same problem,everything fine in expo client app when i detaching my project and i run in xcode i got same error ld: library not found for -lAmplitude-iOS
clang: error: linker command failed with exit code 1 (use -v to see invocation) .
anybody have solution !!???
Can you paste the contents of your Podfile and package.json as well? I’m still not able to reproduce this behavior with a new project.
Hope this is helpful with the linking errors. As stated before I can send you the entire project if that can help.

same issue:
Cocoapods version is 1.2.1
error: linker command failed with exit code 1 (use -v to see invocation)
Anyone working on this issue?
Make sure that you are opening proper xcode file .xcworkspace
Regards
this problem doesn’t seem to be resolved- i am getting the exact same Apple Mach-O Linker (Id) Linker command failed error. Please respond if anyone has resolved the issue
Hello! Sadly “linker command failed error” is just a generic message which indicates that any number of things could have failed when Xcode tried to link your project. Without other information, we have no way of knowing if anybody in this thread is reporting the same issue, or a variety of different issues that happen to all break the linker.
I’m going to close this particular thread since it’s very old, full of a variety of potentially unrelated problems, and more likely to cause confusion than to help anybody.
As a generic hint, here’s what I would try:
pod install and you are opening the xcworkspace file rather than the xcodeproj file.Podfile and any other error output besides the message “linker command failed”.
