...You can build apps with Xcode and the official SDK from Apple with this. I also made a small example app for using the libraries with Xcode and the iPhone/iPhone Simulator. This repository contains an iOS 15.0 Xcode Project which uses the OpenSSL Libraries. The examples uses the MD5 or SHA256-algorithm to calculate an md5 or sha256 hash from an UITextfield. iOS 12.0 - iOS 16.2 (x86_64 , arm64, arm64e bitcode), tvOS 12.0 - tvOS 16.2 (x86_64, arm64, bitcode), WatchOS 8 and MacCatalyst 15.6 (MacOSX_x86_64) are currently supported.
