RxTimelane provides RxSwift bindings for profiling RxSwift code with the Timelane Instrument.
Note: To observe the output of using TimelaneCombine you need to install the Timelane Instrument in advance. More information at: http://timelane.tools.
Import the RxTimelane framework in your code:
import RxTimelaneUse the lane(_) operator to profile a subscription via the TimelaneInstrument. Insert lane(_) at the precise spot in your code you'd like to profile like so:
downloadImage(at: url).
.lane("Download: \(url.path)")
.assign(to: \.image, on: myImageView)Then profile your project by clicking Product > Profile in Xcode's main menu.
Select the Timelane Instrument template:
Inspect your subscriptions on the timeline:
For a more detailed walkthrough go to http://timelane.tools.
Use lane("Lane name") to send data to both the subscriptions and events lanes in the Timelane Instrument.
lane("Lane name", filter: [.subscriptions]) sends begin/completion events to the Subscriptions lane. Use this syntax if you only want to observe concurrent subscriptions.
lane("Lane name", filter: [.events]) sends events and values to the Events lane. Use this filter if you are only interested in values a subscription would emit (e.g. for example subjects).
Additionally you can transform the values logged in Timelane by using the optional transformValue trailing closure:
lane("Lane name", transformValue: { value in
return "Value: \(value)"
})I . Automatically in Xcode:
- Click File > Swift Packages > Add Package Dependency...
- Use the package URL
https://github.com/icanzilb/RxTimelaneto add TimelaneCombine to your project.
II . Manually in your Package.swift file add:
.package(url: "https://github.com/icanzilb/RxTimelane", from: "2.0.0")CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate RxTimelane into your Xcode project using CocoaPods, add it to your Podfile:
pod 'RxTimelane', '~> 2.0'Not supported. More info
This repo contains a simple demo app. To give it a try open RxTimelaneExample/RxTimelane.xcodeproj and run the "RxTimelaneExample" scheme.
