Xcode 默认只有对应的的模拟器，我们作为开发者就必须适配多个版本的系统.这个时候就需要我们在多个模拟器中进行联调适配.但由于网络问题,下其它版本的模拟器总是下载一半又失败,并Xcode还没断点续传,一直下载不了,下面提供方法思路,一劳永逸.(至少目前是这样的.)
- 打开
Xcode, 进入Preference中的Components面板
- 点击任意的下载按钮，稍等一会儿，进入
~/Library/Caches，能看到com.apple.dt.Xcode文件, 就可以取消下载了。 - 点击击
com.apple.dt.Xcode文件选择显示包内容 - 进入
Downloads目录 (如果没有, 则手动创建一个 Downloads 目录) - 将下载好的文件移动到
Downloads目录 (不要改动文件名) - 重启
Xcode, 回到Components面板, 点击对应下载好的 Simulator - 静静等待奇迹的发生~~~
