最近在使用fastlane的时候，发现踩了不少坑，但是大部分由于时间的原因没能即使记录下来
这次简单的记录了一下前两天遇到的一个坑
事情是这样的，由于公司的一个测试机不知道被谁脑残似的点点了升级，于是系统直接到11.3，从而导致我的Xcode版本不支持对应真机的调试，
于是想着网上找对应的真机包，发现并没有找到，可能是我搜索能力不行，如果你有最新的，多多分享哦。
然后我就开始升级Xcode，但是发现升级Xcode又要升级系统，麻蛋。
- 于是就有了下面的一路
升级系统
升级Xcode 9.3
编译一下，发现报错，报错的位置是WCDB，
于是在官方群里问了一下，发现是WCDB的一个大坑，于是github有人提出了两种方式
在 Xcode 9.3 来 Swift 4.0.3 的方法，该方法可以临时解决 WCDB 的问题。
1. 下载并安装 Swift 4.0.3 的 toolchain: https://swift.org/builds/swift-4.0.3-release/xcode/swift-4.0.3-RELEASE/swift-4.0.3-RELEASE-osx.pkg
2. 在 Xcode 中选择 Preferences -> Components -> Toolchains，选择 Swift 4.0.3 Release
3. Clean 并重编你的 Xcode 工程
综合考虑之后，我暂时选择放弃的那台11.3的真机调试功能，只能通过扫描安装
- 于是又有了下面的一路
下载并安装Xcode 9.2
编译项目

就在下班的时候，准备打包，没过几分钟就发现，变态的fastlane报错了（这是要闹哪一出，我都打算打完包直接闪人的）

我尝试着杀进程，重启电脑，升级fastlane，然而并没有什么卵用
于是网上到处寻找答案：
按照stack中的方案一，卸载fastlane重新安装，捣鼓了一会打算重新打包的时候，还是这个错，我就很奇怪了，
然后，我整理了一下思路
- Xcode9.2直接升级到9.3，升级和运行fasrlane，再次安装9.2，于是有了两个Xcode，当时我就蒙圈了
就根据具体问题网上找到了一个重置默认Xcode的方式：
sudo xcode-select --switch /Applications/Xcode\ 9.2.app/Contents/Developer
以上错误是因为安装了 xcode , 但并不是系统默认的位置, 所以可以使用以下命令把 xcode 的路径修改为你安装的位置即可
switch后面部分就是安装的 xcode 的自定义路径.
再次运行fastlane，发现成功了，当时我真想扇自己两耳光.
这问题貌似并没有撒难度，只是当时急着上线，有点脑残了，耗费了我将近4个小时，然后悄悄的回家了，
