InjectionIII is a macOS application that injects changes to Swift and Objective-C source code into a running iOS/tvOS/macOS app without rebuilding or restarting it. It dramatically shortens the edit-run cycle for Xcode developers by patching compiled code at runtime.
Use cases
- speed up iOS development iteration times
- inject Swift code changes into a running app without rebuilding
- avoid full Xcode rebuilds when tweaking UI code
- live-update view controllers while the simulator is running
- reduce compile times during SwiftUI or UIKit development
When to choose
- you develop iOS, tvOS, or macOS apps in Xcode and want near-instant feedback on code changes
- you want to iterate on UI layout and logic without waiting for full builds
- you work primarily in the iOS simulator
When to avoid
- you need injection on a physical device (sandboxing prevents it)
- your project relies on adding new methods or classes at runtime, which is unsupported
- you use a very recent Xcode/Swift version that the tool has not yet been updated for
