I am experiencing the same issue as well. on my IOS12 device, without calling any scanner function, it crashes

[egops]

Can the developers of this project help take a look at how to implement the solution I provided in this plugin?

[navaronbracke]

I can have a look to see if switching on that linker flag fixes it for now.

any progress?

After I update xcode to version 15.1, it solved

[navaronbracke]

@arnabonetraker As stated above, could you try switching to XCode 15.1 ?

[arnabonetraker]

I haven't faced any crashes so far after updating to xcode 15.1, so maybe yeah it was fixed with their update

[navaronbracke]

Then I will close this issue. If it ever happens again, we can reopen this issue.
