Solution 1:
- You can get this type of error if your class' .m file is not listed under the "Compile Sources" step of the "Build Phases" tab of your target. Normally Xcode does this for you, but sometimes it loses the plot and you need to add the .m file manually.
- To do this:
TargetSettings -> Build Phases -> Compile Sources -> add your .m class ->Build and Run
Solution 2:
- Check the Valid Architectures & Build Active Architecture only properties.
Solution 3:
- If you are using cocoapods make sure your target's build settings contain $(inherited) in the other linker flags section
Solution 4:
- If you importing some other project in xcode and if current and import project both have same files in Compiler source then just remove same file in current project in "Build phase' settings.
