問題：
modified: SwiftDemo (modified content, untracked content)
SwiftDemo目錄沒有被跟蹤术唬，嘗試幾次都沒有add上去薪伏，從SourceTree上看SwiftDemo只是一個空目錄，目錄下的文件沒有加進去粗仓。
解決辦法：
SwiftDemo目錄里有一個.git目錄嫁怀，就是說SwiftDemo本身也是一個代碼庫。
admin:SwiftDemo Red$ rm -rf .git
刪除.git目錄后借浊，git add . 還是不行塘淑。
最后把SwiftDemo目錄移動到其它目錄，再移回去蚂斤，git add . 正常存捺。
