Frida 12.1.0 for iOS breaks "String(some_nsobject)"

[pachoo]

I noticed that with Frida 12.1.0 that objection explore blows up with a message [hook failure] cannot string coerce Symbol.

this is happening in objection/hooks/ios/device-information.js where the lines constructing a String from an NSObjecty thing no longer work.

            data: {
                applicationName: String(NSBundle.mainBundle().objectForInfoDictionaryKey_('CFBundleIdentifier')),
                deviceName: String(UIDevice.currentDevice().name()),
                systemName: String(UIDevice.currentDevice().systemName()),
                model: String(UIDevice.currentDevice().model()),
                systemVersion: String(UIDevice.currentDevice().systemVersion()),
                identifierForVendor: String(UIDevice.currentDevice().identifierForVendor())
            }

Switching to using .toString() instead seems to fix the issue.

I don't know if this behavioral change in Frida 12.1.0 was intentional or not, but there should be no issue changing these.

Oh snap thanks for the report! Will make some time today to quickly test this one out and push a fix.

Should be fixed in v1.4.2. pip3 install --upgrade objection to get it!

@leonjza thanks! Next time I'll fork and actually submit a PR :)
