I am struggling to build app with unity on xcode. In the beginning, I could not build the app on my iPhone from xcode because I got this error
我正在努力在 xcode 上统一构建应用程序。一开始，我无法从 xcode 在我的 iPhone 上构建应用程序，因为我收到了这个错误
This iPhone 8 (Model A1863, A1905, A1906, A1907) is running iOS 12.1.2 (16C101), which may not be supported by this version of Xcode.
此 iPhone 8（型号 A1863、A1905、A1906、A1907）运行的是 iOS 12.1.2 (16C101)，此版本的 Xcode 可能不支持。
I also tried to install the older version xcode but it did not work since it requires new version as mentioned above.

Xcode can't be installed on “Macintosh HD” because macOS version 10.13.6 or later is required.
Xcode 无法安装在“Macintosh HD”上，因为需要 macOS 版本 10.13.6 或更高版本。
I am using version 10.12.6 macOS Sierra and I think that there should be available installation version 10.13.6 on my App Store but 10.13 doesn't show up in my app store updates section. Therefore, I went to Apple official page to upgrade to 10.13 but it said that this update requires macOS version 10.13. I cannot install even version version 10.13.
我使用的是 10.12.6 版 macOS Sierra，我认为我的 App Store 上应该有可用的安装版本 10.13.6，但 10.13 没有出现在我的 App Store 更新部分。所以，我去苹果官网升级到10.13，却说这次升级需要macOS 10.13版本。我什至无法安装 10.13 版。
How can I update my OS and install xcode to solve this issue ?
