I have MacBook Pro 2012 mid - Mac OS High Sierra (10.13.6).
- I used the same laptop but Yosemite and Xcode 7.1 for a long time.
And then upgraded High Sierra and Xcode 10.0.
But it takes a long time to run and shows up a plenty of warning.
I expected it should be better than lower mac OS and Xcode version though.
Q: Which version of Xcode is the best for mine, not getting slow?
