Hot reloading as a Swift Package
.package(url: "https://github.com/johnno1962/HotReloading.git", from: "1.5.8")

Yes, HotReloading for Swift & Objective-C

The InjectionIII app available as a Swift Package. i.e.:


Then you can do this... Icon

To try out an example project that is already set-up, clone this fork of SwiftUI-Kit.

To use on your project, add this repo as a Swift Package to your project and add the following "Run Script" "Build Phase" to run the HotReloading daemon:

if [ -d $SYMROOT/../../SourcePackages ]; then
elif [ -d "$SYMROOT"/../../../../../SourcePackages ]; then

You should see a message that the app has connected and which directories it is watching for source file changes. The daemon also has an icon on the menu bar you can use to access features such as tracing and remote control. This script also patches your project slightly to add the required "-Xlinker -interposable" "Other Linker Flags" so you will have to run the project a second time after adding the HotReloading package and and the script build phase for hot reloading to start working.

Consult the REAME of the InjectionIII project for more information in paticular how to use it to inject SwiftUI using the HotSwiftUI protocol extension. It's the same code but you no longer need to download or run the app and the project is selected automatically.

If you want to work on the hot reloading code, clone this repo and drag its directory into your project in Xcode and it will take the place of the configured HotReloading Swift Package when you build your app.

The App Tracing functionality uses the OliverLetterer/imp_implementationForwardingToSelector trampoline implementation via the SwiftTrace project under an MIT license.

SwiftTrace uses the very handy https://github.com/facebook/fishhook as an alternative to dyld_dynamic_interpose. See the project source and header file included in the app bundle for licensing details.

This project includes code for video capture adapted from acj/TimeLapseBuilder-Swift

This release includes a very slightly modified version of the excellent canviz library to render "dot" files in an HTML canvas which is subject to an MIT license. The changes are to pass through the ID of the node to the node label tag (line 212), to reverse the rendering of nodes and the lines linking them (line 406) and to store edge paths so they can be coloured (line 66 and 303) in "canviz-0.1/canviz.js".

It also includes CodeMirror JavaScript editor for the code to be evaluated in the Xprobe browser under an MIT license.
