RCTWebSocket - Ignoring return value of function declared with warn_unused_result attribute

Question

I am currently working on a React Native project. Literally, out of nowhere, I just began to experience this error in XCode.

I've done a good amount of Googling to no avail. Has anyone experienced this? More importantly, does anyone have a resolution?

Answer 1

To make this clear:

• Select the error
• click the build settings tab
• look for Apple LLVM 8.0 Custom Compiler Flags
• select the 'other warnings' entry
• select each flag, click the - to remove them.

This makes the build work.
