How many times you have to build and run your whole project when you just want to run a small piece of code to test a tiny doubt ?
Now with VWInstantRun, you won't run into this situation any more. An Xcode plugin let you build & run your selected lines of code in Xcode without running the whole project, you'll have the output instantly in your Xcode console.
Installation: You can clone or just download the project, then open project with Xcode, build and run project, and finally restart Xcode to active plugin.
Another way more easier option: This plugin can also be installed using Alcatraz.
Just search for VWInstantRun in Alcatraz.
Generally you just select your code in Xcode, then either use hotkey ⌘⌥⇧ + R or go to Product -> Instant Run to
build and run the lines of code selected.
The purpose of this plugin is to run your code snippet instantly without building the whole project, so obviously it do have some limitations. The code selected should be isolated from other contexts, otherwise you will only have some compiler errors when you run that code snippet. Usually you need to add some stub values as input and add print() phrase to actually view your output in console view. For now, it only support Foundation module.
This plugin is still in a very early stage, here is a TODO list to show you a simple roadmap.
- Swift code support.
- Objective-C code support. (In progress, should be done soon)
- More modules support.
- Run selected code with arguments inputed by user.
- You can checkout more implementation details in this blog post.
