I have facing this issues when running ,this issues found in crypto swift frame work please check and fix it

[jesuasir007]

pod 'web3swift', :git => 'https://github.com/lvyikai/web3swift'

I have used but it's fixed ,it's show some bugs Cannot find 'keystoreManager' in scope

[jesuasir007]

let pkData = try! keystoreManager.UNSAFE_getPrivateKeyData(password: pw, account: ethereumAddress).toHexString()

[jesuasir007]

keystoreManager not found

[RaviRanjan-11]

`private var aKeyStoreManger: KeystoreManager?

fileprivate func getPrivateKey() {
    
    DispatchQueue.main.async {
        self.walletAddressLabel.text = self.walletAddress
    }
    
    guard let manager = FilestoreWrapper.getKeystoreManager() else {
        print("Manager not found ")
        return
    }
    aKeyStoreManger = manager
    self.walletAddress = self.aKeyStoreManger?.addresses.first?.address
    if let address = self.walletAddress {
        let ethereumAddress = EthereumAddress(address)
        print(ethereumAddress, " is the ethereum addess ")
        do {
            let privateKeydata = try aKeyStoreManger?.UNSAFE_getPrivateKeyData(account: ethereumAddress).hex
            print(privateKeydata as Any, " iss the private key ")
            if let key = privateKeydata {
                self.privateKeyString = key
               
            }
        } catch {
            print(error.localizedDescription)
        }
    }
}`

Create another file for keystore and you can use anywhere class FilestoreWrapper: NSObject { static func getKeystoreManager () -> KeystoreManager? { let userDir = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] let path = userDir+"/keystore/" let userLoginType = UserDefaults.standard.value(forKey: KeyConstants.UserDefaults.kUserLoginType) as? String ?? "create" return KeystoreManager.managerForPath(path, scanForHDwallets: true, suffix: "json") } static func getWalletAddress () -> String? { return getKeystoreManager()?.addresses.first?.address } }

PLEASE LET ME KNOW IF THERE SNY ISSUE

update your Podfile pod 'web3swift', :git => 'https://github.com/skywinder/web3swift.git' then pod update

[soharang]

This problem is caused since the latest official release of web3swift is a bit old and uses CryptoSwift 1.0.0. If you can update CryptoSwift from 1.0.0 to ~> 1.3.2, the problem must be solved. https://github.com/skywinder/web3swift/pull/330 fixes this problem. You can refer to also this issue.

update your Podfile pod 'web3swift', :git => 'https://github.com/skywinder/web3swift.git' then pod update

This is a good solution and will work when you use Podfile in a project whose dependencies are managed by CocoaPods.

---

Here is the same issue but in a different place. When developing a framework and using *.podspec there is no option to specify the source URL (correct me if I'm wrong) making it impossible to use web3swift as a dependency because it fails on pod lib lint. https://github.com/CocoaPods/CocoaPods/issues/4921#issuecomment-801286927

Note that there is an Unreleased version of the web3swift in CocoaPods repository that will solve this issue: https://cocoapods.org/pods/web3swift#changelog

Here is my podspec:

Pod::Spec.new do |s|
    s.name             = 'my-framework'
    s.version          = '0.1.0'
    s.summary          = 'My first framework'
    s.description      = <<-DESC
    My first framework: the main goal is to learn.
    DESC
    
    s.homepage         = 'https://github.com/JeneaVn/my-framework'
    s.license          = { :type => 'MIT', :file => 'LICENSE' }
    s.author           = { 'Evghenii Vranceanu (JeneaVn)' => '[email protected]' }
    s.source           = { :git => 'https://github.com/JeneaVn/my-framework.git', :tag => s.version.to_s }
    s.ios.deployment_target = '11.0'
    s.swift_version = '5.0'
    s.source_files = 'my-framework/Classes/**/*'
    
    s.dependency 'Alamofire', '~> 5.4'
    s.dependency 'web3swift', '~> 2.3.0'
    
end

Here is the output of pod lib lint --no-clean:

$ pod lib lint --no-clean

@skywinder Maybe there is something blocking you from releasing the "Unreleased" version?
