Swift SDK 报线程警告错误

IDE：Xcode14 Version 14.0 (14A309)
问题：通过SMP集成后，初始化即报线程警告
位置：Sources - Foundation - Extension - 第312行代码
'''
func expect(_ task: @escaping (_ fulfill: @escaping (T) -> Void) throws -> Void) rethrows -> T {
var result: T!

let dispatchGroup = DispatchGroup()

dispatchGroup.enter()

try task { value in
    result = value
    dispatchGroup.leave()
}

dispatchGroup.wait()

return result

}
'''
错误内容：
/Users/amos/Library/Developer/Xcode/DerivedData/AmosGym-btebomjeycktrwftqekiucmchfrm/SourcePackages/checkouts/swift-sdk/Sources/Foundation/Extension.swift:312: warning run: Thread running at QOS_CLASS_USER_INTERACTIVE waiting on a lower QoS thread running at QOS_CLASS_DEFAULT. Investigate ways to avoid priority inversions

最后：开发版连汇报bug的工单都无法创建这是我没有想到的，望尽快修复。

SDK就是swift版本master最新的版本，从去年11月到现在没更新过的17.10.1。
https://github.com/leancloud/swift-sdk
初始化使用教程里说的：
LCApplication.default.set()
每次调用object.save()储存数据都会报错

每次都会出现的错误详情：
保存LeanCloud数据成功：

今天使用object.fetch()，指定属性刷新的时候，数据decode的时候报错崩溃了。

原因是nil直接调用.stringValue
