I recently upgraded to new beta version of macOS 10.14 but after installing it when I tried to open my older version of Xcode 8.3.2, every time it gets crashed. Below is its details.

Symbol not found: _OBJC_IVAR_$_NSTextViewIvars.sharedData

Answer 1

Xcode 8.X.X is doesn't support on macos 10.12 later version.

Cause of issue: "DYLD, [0x4] Symbol missing"

and also doesn't meet the swift version. so you need to upgrade your Xcode version or downgrade your os version below 10.12

Answer 2

As discussed in a few places like here and here, Xcode 8 does not run on Mojave. The best approach at this point is to either migrate your application to run with the latest Xcode, or run a VM with High Sierra or earlier that still supports your required version of Xcode.
