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

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.

I also tried to install the older version xcode but it did not work since it requires new version as mentioned above.

Then, I attempted to reinstall xcode now and got error

Xcode can’t be installed on “Macintosh HD” because macOS version 10.13.6 or later is required.

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.

How can I update my OS and install xcode to solve this issue ?

You need to download macOS version 10.13.6. You can download it from here You may need to have a developers account but you can get a free one by going to Apple developers. You may need to google that. Once you get 10.13.6 loaded you can then download Xcode 10.1
