(ios) Apple Mach-O Linker Error

[datnguyen0606]

Hi,
I got error "Apple Mach-O Linker Error" when trying to build the app from XCode.
Could you guys help me to figure out how to fix this issue?
Thanks

Open YourAppName.xcworkspace instead of YourAppName.xcodeproj and build again

We also had a similar issue, when running custom configuration (something other than Debug/Release, e.g Staging).

I think it is somewhat related to facebook/react-native#11813, and even though it looked like facebook/react-native#11813 (comment) would solve our issue, that was not the case.

Instead, I opened YourAppName.xcworkspace as @sksahil030 suggested and relinked libPods-YourAppName.a with the following steps

• Press YourAppName in the Project navigator
• Select YourAppName as the target
• Go to General and scroll down to Linked Frameworks and Libraries
• Remove libPods-YourAppName.a and add it again (either by + or drag it from Pods -> Products)

Hope this helps anyone with a similar issue!
