In the XCode, if I build then I get such these 2 errors.

RCTWebSocket 2 issues

• XCode 8.0
• Mac OS X EI Captain
• Node v6.4
• npm v3.10.7

I check this issue in the previous closed issues. but currently it is not working on my side.
How can I do?

[davidtian719]

I removed XCode 8.0 and reinstall XCode7.3.1, then building is okay.

[davidtian719]

Yes, version is 0.28.
The building was okay. But it is not working in the simulator again.
Error message is "Native module cannot be null.".

@TianDaGe I am getting build errors for the iOS app. I am going to try uninstalling Xcode 8 and installing 7.3.1 as you suggest. Please tell me, is your react-native version 0.28?

[davidtian719]

Yes, version is 0.28.
The building was okay. But it is not working in the simulator again.
Error message is "Native module cannot be null.".

[StuartAshby]

I got that same error, but was able to fix it by first making sure I had Xcode 7.3.1 installed and then starting all over from scratch from the instructions here https://github.com/fbsamples/f8app/blob/master/README.md. I've got the app opening in the iOS Simulator now.

[davidtian719]

When f8app and react-native-fsdk will be suitable with XCode8 and iOS10.0.1?

[gavinxyang]

Same question here.

[jiazil]

Same question for me.

For build error, if using xcode8, open F8v2.xcworkspace in xcode, then you will find some _refreshControl errors. Change _refreshControl to refreshControl, then the build will pass.

For Native module be null, ...undefined...issues, please check out https://github.com/fbsamples/f8app/issues/106#issuecomment-242624950
