SiliconDevKit vs Xcode
When to describe a Mac app to SiliconDevKit, and when to write it yourself in Xcode.
Xcode is Apple's free development environment. It is where most Mac apps are written, tested, signed and submitted to the App Store. SiliconDevKit is a way to get a small, working Mac app by describing it in plain English, without installing or learning Xcode.
At a glance
| SiliconDevKit | Xcode | |
|---|---|---|
| You provide | A description of the app | The code (Swift or Objective-C) |
| You need a Mac to build | No | Yes |
| Output | A downloadable .app (as a .dmg or .zip) | Whatever you build and package yourself |
| Learning curve | Write sentences | Learn Swift, SwiftUI and Xcode |
| App size and complexity | Small single-target SwiftUI apps | Anything Apple supports |
| Signing and notarization | Ad-hoc signed; you notarize yourself | Built in, with your Apple Developer account |
| Mac App Store | Not directly; extra steps | Yes |
| Cost | Free samples, then $29 a month | Free (the Apple Developer Program is $99 a year if you distribute) |
Choose SiliconDevKit when
- You want a small utility, menu bar tool, notes app or visual toy and do not want to write code.
- You do not have a Mac to build on, or do not want to set up the toolchain.
- You want to try an idea in a minute and change it by sending another message.
Choose Xcode when
- You need full control of the code, or an app that is large, has a server, or uses special Apple permissions and services.
- You are shipping to the Mac App Store, or need sandboxing, extensions or in-app purchases.
- You want to learn to build Mac apps yourself.
They work together
The Swift package SiliconDevKit builds is ordinary SwiftUI code. Nothing stops you from continuing in Xcode with your own copy of the source if you want to take an app further.
