ios.previewDocument is not working anymore

Hi Everyone! Around two weeks ago previewDocument was broken for me without any packages updates. Before that, I was able to download PDFs and preview them also. Now only an empty file is coming.

Here is my code:

RNFetchBlob.config({
	fileCache: true,
	indicator: true,
	addAndroidDownloads: {
		useDownloadManager: true,
		notification: true,
		mime: 'application/pdf',
		title: `${fileName}`,
		path: `${dirs.DownloadDir}/${fileName}`,
		description: 'Diagnostic result',
	},
})
	.fetch('GET', `${BACKEND_URL}/${url}`, {
		Authorization: `Bearer ${authToken}`,
	})
	.then((res) => {
		const status = res.info().status;

		if (status === 200) {
			RNFetchBlob.fs.writeFile(filePath, res.data, 'base64');
			RNFetchBlob.ios.previewDocument(filePath);
		}
	})

I checked and file is being saved correctly in the temporary folder and it’s not empty there, but then when I read it with ios.previewDocument, the file is always empty. in popup which is appearing. After copying it’s also empty, in quick-look it’s also empty.

"rn-fetch-blob": "0.11.2" "react-native": "0.61.2"

I figure out my problem, I was pointing to RNFetchBlob.fs.dirs.DownloadDir, but this is only available for Android. Changed to point to RNFetchBlob.fs.dirs.DocumentDir.

Hey @qasimgit,

I would suggest finding a different library as this has been archived
