A customizable gradient progress bar (UIProgressView). Inspired by iOS 7 Progress Bar from Codepen.
To run the example project, clone the repo, and open the workspace from the Example directory.
- Swift 5.0
- Xcode 11
- iOS 9.0+
CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate GradientProgressBar into your Xcode project using CocoaPods, specify it in your
pod 'GradientProgressBar', '~> 2.0'
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate GradientProgressBar into your Xcode project using Carthage, specify it in your
github "fxm90/GradientProgressBar" ~> 2.0
Run carthage update to build the framework and drag the built
GradientProgressBar.framework, as well as the dependency
LightweightObservable.framework, into your Xcode project.
Swift Package Manager
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the
swift compiler. It is in early development, but Gradient Progress Bar does support its use on supported platforms.
Once you have your Swift package set up, adding Gradient Progress Bar as a dependency is as easy as adding it to the
dependencies value of your
dependencies: [ .package(url: "https://github.com/fxm90/GradientProgressBar", from: "2.0.3") ]
How to use
Simply drop a
UIView into your View Controller in the Storyboard. Select your view and in the
Identity Inspector change the class to
Don't forget to change the module to
Setup the constraints for the
UIView according to your needs.
GradientProgressBar in your view controller source file.
IBOutlet of the progress view in your view controller source file.
@IBOutlet weak var gradientProgressView: GradientProgressBar!
After that you can set the progress programmatically as you would do on a normal UIProgressView.
gradientProgressView.setProgress(0.75, animated: true)
gradientProgressView.progress = 0.75
Adjusts the animation duration for calls to
progressView.animationDuration = 2.0 progressView.setProgress(progress, animated: true)
Adjusts the colors, used for the gradient inside the progress-view.
progressView.gradientColors: [UIColor] = [ .red, .white, .blue ]
Adjusts the timing function for calls to
setProgress(_:animated:), with animated set to
progressView.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut)
Interface Builder Support
Unfortunatly the Interface Builder support is currently broken for Cocoapods frameworks. If you need Interface Builder support, add the following code to your Podfile and run
pod install again. Afterwards you should be able to use the
GradientProgressBar inside the Interface Builder :)
post_install do |installer| installer.pods_project.build_configurations.each do |config| next unless config.name == 'Debug' config.build_settings['LD_RUNPATH_SEARCH_PATHS'] = [ '$(FRAMEWORK_SEARCH_PATHS)' ] end end
Source: Cocoapods – Issue 7606

Based on my gist, the example application also contains the sample code, for attaching the progress view to a
UINavigationBar. Using "Key-Value Observing" we change the progress of the bar accordingly to the property
estimatedProgress of the
Please have a look at the example application for further details :)
