Before building a Passport App, you must have an Apple Developer account. Without this account, you cannot build and deploy Passport App.
To build Passport App:
Launch the Passport App in Xcode by double-clicking the NokNokPassport.xcodeproj file.
Connect a Touch ID or Face ID-capable device to your build machine.
Select the connected iOS device as the target.
Click ► to build and run on the device.
Apple enforces that apps in its ecosystem must have a unique bundle ID. Since your version of Passport App is different from Nok Nok's version, you must provision a bundle ID. See the Apple documentation.
