About The Project

With this project, we can edit, crop and share photos on social media with presets filters.

Here's why:

• To learn CoreImage and Photos Library
• To learn RxSwift and reactive programming.

Built With

The frameworks I used in this project are listed below.

• RxSwift
• CoreImage
• Photos

Getting Started

This is an example of how you may give instructions on setting up your project locally. To get a local copy up and running follow these simple example steps.

Requirements

• Xcode 12.x
• Swift 5.x

For Xcode 11 and below, use RxSwift 5.x.

Installation

RxSwift doesn't contain any external dependencies.

These are currently the supported installation options:

Manual

Open Rx.xcworkspace, choose RxExample and hit run. This method will build everything and run the sample app

CocoaPods

# Podfile
use_frameworks!

target 'YOUR_TARGET_NAME' do
    pod 'RxSwift', '6.1.0'
    pod 'RxCocoa', '6.1.0'
end

# RxTest and RxBlocking make the most sense in the context of unit/integration tests
target 'YOUR_TESTING_TARGET' do
    pod 'RxBlocking', '6.1.0'
    pod 'RxTest', '6.1.0'
end

Replace YOUR_TARGET_NAME and then, in the Podfile directory, type:

$ pod install

Usage

Here's an example
Filter a photo...
private func applyFilter(to inputImage: UIImage, value: Float, myFilter: Filters, completion: @escaping ((UIImage) -> ())) { let filter = CIFilter(name: myFilter.filterName)! filter.setValue(value, forKey: myFilter.filterKey) if let sourceImage = CIImage(image: inputImage) { filter.setValue(sourceImage, forKey: kCIInputImageKey) if let cgimg = self.context.createCGImage(filter.outputImage!, from: filter.outputImage!.extent) { let processedImage = UIImage(cgImage: cgimg, scale: inputImage.scale, orientation: inputImage.imageOrientation) completion(processedImage) } } }
