2. Sigma Software, 26.01.19 Background • 7+ years in Software Development • Last 4+ years of developing libraries and frameworks for iOS platform 2
3. Sigma Software, 26.01.19 Swift • ABI stability & Swift 5 • Static and Dynamic frameworks (доклад Юлии Васильченко с CocoaHeads 2018) • Swift Binary Frameworks • Peter Steinberg's talk about Swift Binary Frameworks • Understanding Xcode version and Swift version coupling 3
4. Sigma Software, 26.01.19 Distributing Swift library as a binary - sounds… easy, right? • Xcode update hell (delay in getting latest and greatest sources to customers) • Have to support multiple versions of Xcode - welcome to CI matrixes for multiple Xcode versions • Have to store & manage binaries somewhere (welcome to GitHub Releases or other cloud storage’s) • Customer’s resistance in upgrading to latest version of Swift 4
5. Why not to go… open- source?
6. Sigma Software, 26.01.19 Benefits • Transparency & clarity - no binary “black box” magic • Easy to debug • Ready for security review and assessment • Integration is easier - no longer tied to the specific Swift compiler version • Additional contributors • Benefits your CV heavily 6
7. Sigma Software, 26.01.19 Must have things • Unit tests or other proofs of working library • CI setup + status badge • Playground or demo application setup & ready to tryout • License • README.md • CHANGELOG.md • SEMVER2.0.0 7
8. Sigma Software, 26.01.19 Dependency Managers • Currently Swift lacks built in DM :( 
 (comparing to JS and Golang we have the worst dependency managers ) • Support most popular DMs - CocoaPods, Carthage and even SPM if you are doing Swift on Linux :) 8
