Xcode无法建立

Question

昨天晚上我可以在手机或模拟器上构建项目，但是现在我无法使用，因为Xcode正在使用计算机的所有内存，我不知道问题出在哪里，但是昨天我可以构建，今天我不是，我的计算机真的很慢，我没有收到任何错误，但它根本无法构建，我曾尝试清洁，重新启动计算机，运行终端等。

Answer 1

On my last two contracts I was given a mini with 4GB and that is not enough, you will be paging memory and that will make Xcode basically unusable. I upgraded to 16GB and the system was usable.

In the Activity Monitor Application, not in Xcode, look at "Swap Used"; if it is not 0 and you do not have other apps running there is not sufficient memory.

My advice: get 16GB, 8GB is a bare minimum for development. 4GB can work but also can by so slow as to be unusable.
