How to remove the Xcode warning Apple Mach-O Linker Warning 'Pointer not aligned at address

It probably means their binary file has non-aligned pointer when they compile their code. In those cases the alignment basically defaults to 1 byte and hypothetically might impact performance. After updating to Xcode 8.3 public release I am still seeing this error, so Google might need to compile their static library with different settings to make it go away.

Got this response from firebase support:

This is a known issue with Xcode 8.3 beta, so it might be a beta thing and Xcode being extra verbose. It works well though with 8.2.1 so I recommend temporarily use it to avoid the warnings or ignore the warnings on 8.3 beta if it does not affect your app.

This has been fixed in Firebase 3.16.0 (Firebase Core 3.6 + Firebase Analytics 3.8.0)
