Question

I have a slight issue when build my Xcode project, get tones of warning after update pod. It looks like this

Already search the whole site here but still no luck. it doesn't affect the project but it is quite annoying. Anyone could help?

Answer 1

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.

Answer 2

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.
