當我選擇源代碼管理時，Xcode會一直崩潰>歷史記錄

Question

當我選擇源代碼管理>歷史記錄時，我的Xcode總是崩潰。它已經發生了很長一段時間，可能會回到Xcode 6，並繼續通過Xcode 7.2。

我重視其大跌後顯示出來的日誌：

Xcode是試圖解析存儲庫的日誌條目，並有一個與日期的問題。

__NSCFCalendar組件：FROM日期：]：日期不能是零

你需要確定的第一件事是，如果這是具體到一個單一的存儲庫。如果是這樣，存儲庫中的某些內容無效。您可以嘗試運行git fsck以查看它是否識別出任何損壞或丟失的物體。

• 根據問題，您可能能夠修復，恢復或恢復對象。
• 最糟糕的是，您可能必須犧牲全部或部分歷史記錄，方法是初始化新的存儲庫，或者恢復到較早的存儲庫備份，然後提交最新的更改。

如果問題影響所有存儲庫，請確定問題是否特定於您的系統。將存儲庫克隆到不同的系統上，看他們的Xcode是否可以顯示歷史記錄。

• 如果問題是特定於您的系統，這可能是從一個問題的任何與已安裝的軟件包或第三方工具（這會影響您的存儲庫），或已損壞的屬性列表（影響的Xcode或它的工具）。按照嚴重性順序，您可以嘗試：
  • 刪除並重新安裝Xcode。
  • 刪除特定於Xcode用戶數據的〜/ Library/Developer/Xcode中的目錄。
  • 在自定義帳戶和重新安裝其他應用程序和工具的每個步驟中，執行操作系統的全新安裝，恢復您的存儲庫，然後檢查Xcode不會崩潰。

在最壞的情況，這可能不是在Xcode的問題，因此很難對別人有一個具體的答案事業。但是通過系統地採取步驟來確定和解決問題，您應該能夠回到可以查看源代碼管理歷史記錄的狀態。
