These come from GUI code, and haven’t/aren’t being fixed, see discussion in https://github.com/bitcoin-core/gui/issues/112. For now, just ignore them entirely. Note that this only applies to ObjCXX code, so will not hide any relevant warnings coming from C or CXX code (and they would be unlikely in any case).
Alternative to #29362 (which disables all compiler warnings, for macOS builds in the CI). This PR includes one commit from that PR.
