For instance, if your website was www.mywebsite.com, then your BUNDLE ID would be com.mywebsite.yourappname
IMPORTANT — If your website domain or app name starts with a number, then append a letter in front. For instance: www.123test.com would be www.a123test.com / for app name '123test' would be 'a123test'
In this scenario, your bundle ID would be com.a123test.a123test
If you have any special characters in your website url such as hyphens ( — ), then remove the hyphen. For instance, if your website says www.my-website.com, then it would be com.mywebsite.yourappname.
