ive made some local changes to the package to kind of enable that, if it helps, there should definitely be better options.
ScannerViewController.swift
func updateViewController(isTorchOn: Bool, isGalleryPresented: Bool, toReset: Bool) { // new toReset binding
if let backCamera = AVCaptureDevice.default(for: AVMediaType.video),
backCamera.hasTorch
{
try? backCamera.lockForConfiguration()
backCamera.torchMode = isTorchOn ? .on : .off
backCamera.unlockForConfiguration()
}
if isGalleryPresented && !isGalleryShowing {
openGallery()
}
if toReset { // if toReset, use reset function in ScannerCoordinator.swift
delegate?.reset()
delegate?.parent.toReset.wrappedValue = false
}
}
CodeScanner.swift
public var isGalleryPresented: Binding<Bool>
public var toReset: Binding<Bool> // new binding variable
public var videoCaptureDevice: AVCaptureDevice?
...
isGalleryPresented: Binding<Bool> = .constant(false),
toReset: Binding<Bool> = .constant(false), // in init function
videoCaptureDevice: AVCaptureDevice? = AVCaptureDevice.default(for: .video),
...
self.isGalleryPresented = isGalleryPresented
self.toReset = toReset
self.videoCaptureDevice = videoCaptureDevice
...
public func updateUIViewController(_ uiViewController: ScannerViewController, context: Context) {
uiViewController.updateViewController(
isTorchOn: isTorchOn,
isGalleryPresented: isGalleryPresented.wrappedValue,
toReset: toReset.wrappedValue // added this
)
}
Followed this to temporarily overwrite with local changes https://developer.apple.com/documentation/swift_packages/editing_a_package_dependency_as_a_local_package

Tip: there are many cool functions in this package, unfortunately Paul is shy to write about them :(
If you look CodeScanner.swift
, there are many params like shouldVibrateOnSuccess
,isTorchOn
, and even completion
though I haven't figured it out how the last one works.
But the one you need is scanMode
, and when using you can choose from .continuous
,.once
and .oncePerCode
. Seems like for your case .continuous
will be the right one.
This is how my code with specified scan mode looks
CodeScannerView(codeTypes: [.qr], scanMode: .continuous, simulatedData: "Paul Hudson") { response in
switch response {
case .success(let result):
print("Found code: \(result.string)")
case .failure(let error):
print(error.localizedDescription)
}
And using scanInterval
you can specify the time in seconds between the scans (it takes double so you can specify like 0.5 seconds and so on)
In this example I have 10 seconds delay between the scans
CodeScannerView(codeTypes: [.code39], scanMode: .continuous, scanInterval: 10 ,simulatedData: "Paul Hudson") { response in
switch response {
case .success(let result):
print("Found code: \(result.string)")
case .failure(let error):
print(error.localizedDescription)
}
}
Hope this helps!
@Sat1l I'm not too shy, I'm too busy – have you considered perhaps contributing some documentation in the README, given that this is an open source project?
@twostraws seems like fun, just give me some time :) Edit: seems like I'm the one who wasn't reading repo info carefully and there is an actual guidance on .scanmode
Closing as it seems to be solved. If not, please reopen and give details about what you're still struggling with.
Right now, I couldn't find a way to restart a new scanning session, other than using the
continuous
option or making a new instance of the class.
