ASN1Swift provides a transparent interface to decode ASN.1 data structures. The ASN.1 Data Structure must be encoded using BER/DER Encoding Rules. To simplify encoding and decoding process ASN1Swift implement Encoder/Decoder protocol provided by swift foundation. In other words it works preciesly the same as JSONEncoder/JSONDecoder.
To integrate ASN1Swift into your project using CocoaPods, specify it in your Podfile
:
platform :ios, '13.0'
target 'YOUR_TARGET' do
use_frameworks!
pod 'ASN1Swift'
end
Then, run the following command:
$ pod install
In any swift file you'd like to use ASN1Swift, import the framework with import ASN1Swift
.
To integrate using Apple's Swift package manager, add the following as a dependency to your Package.swift
:
.package(url: "https://github.com/tikhop/ASN1Swift.git", .branch("master"))
Then, specify "ASN1Swift"
as a dependency of the Target in which you wish to use ASN1Swift.
Lastly, run the following command:
swift package update
Make the following entry in your Cartfile:
github "tikhop/ASN1Swift"
Then run carthage update
.
If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained over at Carthage.
