Answer 1

A bundle ID or bundle identifier identifies an application in Apple's ecosystem. Apple advice to use reverse domain name(reverse DNS notation) to create it.

For example:

com.companyname

Bundle identifier is a string in Info.plist[About] which is required for any Bundle

To set it using Xcode

//Info.plist
Bundle identifier
//by default it points on `$(PRODUCT_BUNDLE_IDENTIFIER)` which is you can setup in Build Settings

//Build Settings the mirror of Target Settings
Build Settings -> Product Bundle Identifier

//Target Settings the mirror of Build Settings
General -> Bundle Identifier

To get it programmatically

//Objective-C
[[NSBundle mainBundle] bundleIdentifier];

//Swift
Bundle.main.bundleIdentifier
