在下面的类中，构造函数崩溃：

class Locations
    def initialize
        @index = [{}]
        file = File.new(NSBundle.mainBundle.pathForResource('suburbs', ofType: 'txt'), 'r')
        while (line = file.gets)
            location = Location.parse(line)
            for x in 0...@index.length do
            end
        end
        file.close
        self
    end
end

如果我删除 for 循环，它不会崩溃：

class Locations
    def initialize
        @index = [{}]
        file = File.new(NSBundle.mainBundle.pathForResource('suburbs', ofType: 'txt'), 'r')
        while (line = file.gets)
            location = Location.parse(line)
        end
        file.close
        self
    end
end

如果我交换 for 循环和location赋值的顺序，它也不会崩溃：

class Locations
    def initialize
        @index = [{}]
        file = File.new(NSBundle.mainBundle.pathForResource('suburbs', ofType: 'txt'), 'r')
        while (line = file.gets)
            for x in 0...@index.length do
            end
            location = Location.parse(line)
        end
        file.close
        self
    end
end

任何想法？

编辑：这是控制台输出：
