• I have tested this issue on the latest Detox release and it still reproduces

Description

No matter what value I set detoxURLBlacklistRegex to in launchArgs when launching the app, it is always nil when picked up in the native code.

If I replace [options arrayForKey:@"detoxURLBlacklistRegex"];with @[@".*"]; my tests run as expected. I've tried setting the values to all of the following:

• The example: '\\("http://192.168.1.253:19001/onchange","https://e.crashlytics.com/spi/v2/events"\\)'
• '\\(".*"\\)'
• '\\(.*\\)'
• ['.*']

Reproduction

1. Update detox/ios/Detox/DetoxManager.m to print out "blacklistRegex"
2. Run detox tests using detoxURLBlacklistRegex in launchApp (as mentioned in the docs)

Expected behavior

The value should be set to what is passed in detoxURLBlacklistRegex

Environment (please complete the following information):

• Detox: 15.1.2
• React Native: 0.61.5
• Node: 12.14.1
• Device: iPhone 8 (tried on multiple)
