What are the differences between XCFramework and a regular framework in the context of iOS app development?

XCFramework is a framework format introduced by Apple to simplify the distribution of binary libraries supporting multiple platforms and architectures. Key differences from a regular framework:

• Multiplatform support: XCFramework can contain compiled binaries for iOS, iOS Simulator, macOS, watchOS, and tvOS in a single package, whereas a regular framework is usually designed for one platform and architecture.
• Simplified integration: XCFramework helps avoid architecture issues (e.g., arm64 and x86_64) that often occur when using universal frameworks.
• Modularity support: XCFramework is better suited for distributing closed libraries, as it contains only binary files and headers.

Example of using XCFramework in Xcode:

xcodebuild -create-xcframework \
  -framework MyFramework-iOS.framework \
  -framework MyFramework-macOS.framework \
  -output MyFramework.xcframework

Thus, XCFramework is a more modern and flexible way to package libraries for iOS and other Apple platforms.
