Actual results

When I run my app on iOS 14.1 real device, there is a crash from Facebook SDK.
But they just give only Thread 1: EXC_BAD_ACCESS (code=1, address=0x0).

If I don't initalize facebook SDK, then it works to run.
I updated facebook SDK version 14 to 16, but it doesn't work.

How can I fix? Please let me know.

Maybe you can try this solution https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes

Binaries using symbols with a weak definition crash at runtime on iOS 14/macOS 12 or older. This impacts primarily C++ projects due to their extensive use of weak symbols. (114813650) (FB13097713)

Workaround: Bump the minimum deployment target to iOS 15, macOS 12, watchOS 8 or tvOS 15, or add -Wl,-ld_classic to the OTHER_LDFLAGS build setting.

Weak symbol imports are linked as non-weak imports, when used from LTO object files. (115521975) (FB13171424)

Workaround: Add -Wl,-weak_reference_mismatches,weak or -Wl,-ld_classic options to the OTHER_LDFLAGS build setting.

I add -Wl,-ld_classic options to the OTHER_LDFLAGS build setting, and it works! thank you.

Xcode 15.1 should fixed the problem, no need add link flag.
