– 2.1.2 When scan on difference barcode scanner will ignore the delay time
– 2.1.1 Fixed bugs
– 2.1.0 You can draw a box around the barcode
– 2.0.1 Fixed bugs
– 2.0.0 I learned many more things about SwiftUI then I decide to restructure the scanner I hope you will like it. And this version you can switch front and back camera.
– 1.5.0 Fixed bugs and you can read the barcode type when scanner found it
– 1.4.0 Rename component and add new barcode generator view component
– 1.3.0 You can set a mock barcode when running with an iOS simulator.
– 1.2.0 Add feature allows to turn torch light on or off.
– 1.0.1 Fixed bug camera delay 10 seconds when use on modal.
