18. Binary Frameworks
• Now along with swift frameworks we can distribute XCFrameworks
(binary frameworks)
• A single XCFramework can have variant for Simulator and Device.
• Also, it can have variant for any of the platform, iOS, Mac OS, tvOS
and watch OS.
• We can use it to bundle up static libraries like .h or .a files or swift
package or swift and c based code.
• To create XCFramework, update ”Build Libraries for Distribution” and
generate Product Archive.
• xcodebuild –create-xcframework <archive frameworks with space>
