Swift Locksmith：不存储价值

我正在使用https://github.com/matthewpalmer/Locksmith updateData方法.

它在Github Repo上说

as well as replacing existing data,this writes data to the keychain if it does not exist already

try Locksmith.updateData([“some key”: “another value”],forUserAccount: “myUserAccount”)

这就是我所拥有的：

let dictionary = Locksmith.loadDataForUserAccount("gameKeyChainValues")

print("Ended (EndDateAndTimeString)")

do {
   try Locksmith.updateData(["BattleEnd": "12345678"],forUserAccount: "gameKeyChainValues")

}
catch {
    print("Unable to set time")
}

print("This line ran")

if let timeBattleEnded = dictionary!["BattleEnd"] as? String {
    print("Stored for END: (timeBattleEnded)")
}

此行打印(“Ended(EndDateAndTimeString)”)输出：

Ended 19:33:38+2016-08-05

此行打印(“无法设置时间”)不执行任何操作

此行打印(“此行运行”)输出：

This line ran

这一行：print(“存储为END
