App Crash if formatString is Array (iOS)

[two-bridges]

If you pass an array to format attribute, the app running on a physical iOS device will crash.

eg. [formats]="['QR_CODE']"

Error: formatsString.split is not a function

It was my error to try to send an array, but it was very painful to solve this issue in a production app.

I guess it could throw an ugly error but best if it did not to crash the whole app.

Possible Solution:

add typeof formatsString before trying to use formatsString, as shown below:

/node_modules/nativescript-barcodescanner/barcodescanner.ios.js

const getBarcodeTypes = (formatsString) => {
    const types = [];
    if (typeof formatsString === "string" && formatsString) {
        let formats = formatsString.split(",");
        for (let format of formats) {
            format = format.trim();
            if (format === "QR_CODE")
