[iOS] using Xcode recommended settings throws "This function declaration is not a prototype" warnings when deploying the App
Reproduction steps:
1. Create an empty project
2. Switch the platform to iOS
3. Build the project and open it in Xcode
4. Go to warnings tab in Xcode
5. Press on "Update to recommended settings" warning
6. Press "Perform Changes" in the window that appeared
7. Try deploying the project to an iOS device and inspect the warnings tab
Unexpected behaviour: thousands of "This function declaration is not a prototype" warnings are thrown
Reproducible with: 2018.4.22f1, 2020.2.0a13
Tested with Xcode Versions 11.4.1 (11E503a), 11.3.1 (11C504)
Couldn't test with tvOS build because switching to recommended settings removes deployment targets
Notes:
1. The deployed Application seems to work fine
2. The user suggested a workaround: Replacing () with (void) in the function prototypes resolves the warnings
3. A video is attached

Resolution Note (fix version 2020.2):
We have fixed the -Wstrict-prototypes warning, but there are other warnings in Xcode's "recommended settings" that will still be triggered by IL2CPP generated code so some errors are still expected when using recommended settings in Xcode.
