QRCodeSwift: cross-platform/watchOS QRCode generator in Swift (without CIFilter)

QRCodeSwift (swift_qrcodejs)

Cross-platform QRCode generator written in pure Swift, aiming to solve the awkward situation that there's no CIFilter for QRCode generation on Apple Watches.

Installation

Swift Package Manager

with Xcode

More details in the Official Guide, but in general:

1. Select in the menu bar of Xcode: File > Swift Packages > Add Package Dependency
2. Enter https://github.com/ApolloZhu/swift_qrcodejs.git
3. Next, specify the version resolving rule as "Up to Next Major"
4. Finish with choosing QRCodeSwift library and add it to your app target.

with Package.swift

dependencies: [
    .package(url: "https://github.com/ApolloZhu/swift_qrcodejs.git", from: "2.3.0"),
]

... then add QRCodeSwift module/target from package swift_qrcodejs as your dependency.

CocoaPods

pod 'swift_qrcodejs', '~> 2.3.0'

Carthage

I assume you know what you are doing (because I don't), but you probably need something like this:

github "ApolloZhu/swift_qrcodejs" ~> 2.3.0

Note that Carthage doesn't work with Xcode 12 (but here's a workaround).

Manually

Add all the .swift files from the Sources folder into your project.

Usage

import QRCodeSwift

guard let qrCode = try? QRCode("Hello World!") else {
    fatalError("Failed to generate QRCode")
}
print(qrCode.toString(filledWith: "##", patchedWith: "  "))
