How can I translate the following code snippet from Swift to Objective-C?

Question

#if compiler(>=5.5)
if #available(iOS 15.0, *) {
    myTableView.sectionHeaderTopPadding = 0.0
}
#endif

Alternatively, is there any macro in objective c side that assists to know the compiler version?

Cy-4AH suggested and answer that used,

#ifdef __IPHONE_13_0
if (@available(iOS 13.0, *)) {
    ...
}
#endif

However, in my case #ifdef __IPHONE_15_0 is not available in Xcode 12.x.

Of course condition compiler >= 5.5 is not valid for objective-c. What you are trying to achieve? — Cy-4AH, Jan 17 '22 at 07:28
@Cy-4AH I want to build the code for ios15 in xcode12.4 by restricting compilation. — Sazzad Hissain Khan, Jan 17 '22 at 07:34
@Cy-4AH yes, thus that does not help of achieving what I need. — Sazzad Hissain Khan, Jan 17 '22 at 08:02
Yes they should be missing, `_IPHONE_15_0_` appeared in Xcode 13.0 — Cy-4AH, Jan 17 '22 at 08:06
You need somehow put iOS 15 SDK inside Xcode 12. The easiest way to do it is to update to 13 :) — Cy-4AH, Jan 17 '22 at 08:10
@Cy-4AH My MacBook Pro, mid 2012 does not support latest macOS to support xcode13. I need this workaround. — Sazzad Hissain Khan, Jan 17 '22 at 08:26
Try to check the clang version : https://stackoverflow.com/questions/37608546/how-to-know-the-objective-c-language-version-in-xcode — IluSioN, Jan 17 '22 at 09:03

I have managed to solve this problem with a workaround discussed here.

#if __clang_major__ >= 12
    NSLog(@"My Objective-C language support is what Apple Clang/Xcode 12.x can support.");
#endif

Note that the clang_major, clang_minor, etc. variables resemble (are almost the same as) the Xcode versions and need careful investigation before usage.
