In v3 we had the compareWith on ion-selects that allowed us to put our own comparison method in place to handle objects etc.
Whats the best way to do this now in v4 that compareWith is missing?
Hi @Slavrix 
Yeah, I reported this a while back in issue #14598 and a contributor has recently posted PR #17358 to add compareWith back. As a workaround I’m using the select component from Angular Material (not the same thing, I know).
Let’s hope the changes are OK and they get merged soon.
Best,
Rodrigo
