App freezing in ion-input lost focus event - ionic 3 - ionic-framework

Question

I’m facing a problem after to update my MacOS to Mojave version, I don’t know why but now, after to build my project to IOS (It happens only in IOS), I have a problem with a ion-input, that I use to enter a money value, always after to lost the focus my App freezes, Do you Know what can I do to fix it?
I’m using this method to apply a mask in ion-input:

tried to remove this method but I still have the same problem…
When I build the same project in a Android device everything is working fine.
This is my environment
