keychain 生成uuid 使用获取不到数据

 问题 :一直获取不到数据

之前代码

let keychain = KeychainSwift()
        keychain.accessGroup = "xxx.xxxxxxx"
    
        var cuserId: String!
       
        if let userID = keychain.get("cuserId") {
            cuserId = userID
        } else {
            let uuid = UUID().uuidString
            keychain.set(uuid, forKey: "cuserId")
            cuserId = keychain.get("cuserId") ?? ""
            debugPrint(cuserId!)
        }
        print("c_uuid"+cuserId)
        debugPrint("c_uuid"+cuserId)

     keychain.accessGroup = "xxx.xxx"

这句话删掉就行。。可能最新得api里面已经不需要这么设置了 但是他们得文档没有更新

let keychain = KeychainSwift()

    
        var cuserId: String!
       
        if let userID = keychain.get("cuserId") {
            cuserId = userID
        } else {
            let uuid = UUID().uuidString
            keychain.set(uuid, forKey: "cuserId")
            cuserId = keychain.get("cuserId") ?? ""
            debugPrint(cuserId!)
        }
        print("c_uuid"+cuserId)
        debugPrint("c_uuid"+cuserId)

补充 要开启这个功能
