@pmiotto Hi, I see swift_willThrow, do you have Swift Error breakpoint set in Xcode? Just want to confirm this is an Error throwing and not crash

[pmiotto]

Hi, Yes it was just a swift error breakpoint. Closing issue now.

@pmiotto Hi, I see swift_willThrow, do you have Swift Error breakpoint set in Xcode? Just want to confirm this is an Error throwing and not crash

How can I ignore this swift error breakpoint？
