i just follow the apple’s SwiftUi tutorial class (Building Lists and Navigation) and download the file to learn how to code in Swift. when i created a landmarkrow in supporting views. it said that Failed to register bundle identifier. The app identifier “com.example.apple-samplecode.Landmarks” cannot be registered to your development team. Change your bundle identifier to a unique string to try again. And said that (No profiles for ‘com.example.apple-samplecode.Landmarks’ were found: Xcode couldn’t find any iOS App Development provisioning profiles matching ‘com.example.apple-samplecode.Landmarks’.) what should i do ??
Am I need to create a developer account and pay for it if I want to use this file ???
