有没有办法在带有过时版本的Xcode和macOS的iOS 12.2上运行应用程序？

Question

I'm developing a React Native application that I test and build on a real iPhone 7 using Xcode. However, the iPhone recently automatically updated to iOS 12.2, which requires Xcode version 10.2. The problem is that I can't update Xcode because my Mac is running on High Sierra 10.13.6 and is too old to get the Mojave update (2011).

So the question is: Is there any way I can still use the Mac to run the app on my real device, or am I forced to use the emulators/buy a new Mac from now on? Most importantly, is there I way I can still get the Mojave update on my old Mac?

Answer 1

You can download the support files that you want from this repo

Close your xcode, right click on xcode ->Show Package Contents->Contents->Developer->Platforms->iPhoneOS.platform->DeviceSupport, and unzip your file there.

Restart xcode and voilà, your device is supported.

Answer 2

There is some trick for you to install Mojavae and so Xcode 10.2.

I hope that can help you, and think to deactivate the auto update.
