Get application bundle information

You can use this simple struct to easily get app bundle information.

struct App {
    /// Bundle identifier
    static var bundleID: String? {
        Bundle.main.bundleIdentifier
    }
    
    /// Application version
    static var version: String? {
        Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String
    }
    
    /// Build number
    static var buildNumber: String? {
        Bundle.main.infoDictionary?["CFBundleVersion"] as? String
    }
}

print("Bundle identifier: \(App.bundleID ?? "empty")")
print("Version: \(App.version ?? "empty")")
print("Build number: \(App.buildNumber ?? "empty")")
