IOS: Build crash when use_frameworks! :linkage => :static

[JerakRus]

Before submitting a new issue

• I tested using the latest version of the library, as the bug might be already fixed.
• I tested using a supported version of react native.
• I checked for possible duplicate issues, with possible answers.

Bug summary

When trying to build and run an iOS app on a real device with the :linkage => :static setting enabled in the Podfile, a crash occurs.

@JerakRus Thanks for reporting this issue. It has been resolved in version 1.8.0. Please check with the latest release, and if you encounter the problem again, let me know.

Thanks! I've already tested it and the app now launches! But I've encountered a new problem. When the camera modal opens, my app freezes with an error:

Moreover, the error seems to be intermittent; the camera started successfully once and scanned the code.

[pushpender-singh-ap]

@JerakRus - Can you please test this in a new fresh project as well and confirm if you’re getting the same issue?

[JerakRus]

Yes, I also tested this on the example app (I pushed updates to example repository). The problem persists: immediately after receiving permission to access the camera, the app freezes on a black screen and displays an error in the logs. Here's the full log of the entire launch from xCode:

[pushpender-singh-ap]

@JerakRus Thanks for testing. I’ll make some changes and let you know once I’ve finished my testing.

[pushpender-singh-ap]

@JerakRus I tested this issue in version 1.9.0, and it’s now fixed. You may still notice a slight delay in the camera preview at times while the camera configuration is processing, but it will no longer cause the app to crash. Please let me know if everything works fine in your testing as well.

[JerakRus]

That’s great! I tested the latest version on both iOS and Android, and now everything works perfectly everywhere!
I did notice a bit that on Android the focusing has become worse compared to version 1.5.0, and now the camera needs to be brought closer to the QR code. But that’s absolutely not critical!
Thank you very much for the fixes!

[pushpender-singh-ap]

I’m planning the focus-related changes for the next library version. Thanks for the testing and providing feedback; it’s helpful.
