Initialization on iOS take some time

[Johny8811]

Hi guys,

this is my implementation of scanner

`export const scanDocument = async () => {
try {
await readLicence();
} catch (error) {
throw error;
}

try {
await setOCRConfig();
} catch (error) {
throw error;
}

try {
return await showScanner();
} catch (error) {
throw error;
}
};`

I call this method in useEffect but scanner will not start on iOS, without any error.

useEffect(() => { scanDocument(); }, []);

I tried add some timeout. 300ms scanner start correctly, below 300ms scanner doesn't work.

Android works correctly, scanner start immediately after component is mounted.

What is wrong??

Hi @Johny8811,

Are you able to successfully start the scanner in our demo project that is available in this repository?

Thanks!

@Johny8811,

Are you experiencing this issue only with one device or with any physical device you have?

I tried it on iPhone 12 pro 14.4 and on another iPhone 12 14.4.2.

I've tried also to run on iPhone 12 pro but didn't notice what you mentioned. Could you please record and send us the video where you demonstrate the reproduction of the issue in our app? You can send the video to support@regulaforensics.com.

Have you changed anything in our demo project to reproduce the issue?

Thanks!
