---------------------------------------

[~mobidev3], we've been trying to reproduce these warnings without any success. Looks like all file reading operations already run in separate threads:
- readAsText: https://github.com/apache/cordova-plugin-file/blob/21298dce51568a2662adee8ff4bfc9b8c838d3a7/src/ios/CDVFile.m#L860-L879
- readAsDataURL: https://github.com/apache/cordova-plugin-file/blob/21298dce51568a2662adee8ff4bfc9b8c838d3a7/src/ios/CDVFile.m#L901-L914
- readAsArrayBuffer: https://github.com/apache/cordova-plugin-file/blob/21298dce51568a2662adee8ff4bfc9b8c838d3a7/src/ios/CDVFile.m#L935-L946
- readAsBinaryString: https://github.com/apache/cordova-plugin-file/blob/21298dce51568a2662adee8ff4bfc9b8c838d3a7/src/ios/CDVFile.m#L959-L971

If your issue still actual, please post a repro code that produces the warning.
