            //ok
            make.left.equalTo(self.view.mas_safeAreaLayoutGuideLeft);
            make.right.equalTo(self.view.mas_safeAreaLayoutGuideRight);
            make.top.equalTo(self.view.mas_safeAreaLayoutGuideTop);

        } else {
            make.edges.equalTo(self.view);

Same here!

[yimao009]

same here; why demo is ok?

When using leading and trailing it crashes (left and right are ok). I guess this is why using edges crashes too as it'll translate to use leading and trailing

//crash make.leading.equalTo(self.view.mas_safeAreaLayoutGuideLeft); make.trailing.equalTo(self.view.mas_safeAreaLayoutGuideRight); make.top.equalTo(self.view.mas_safeAreaLayoutGuideTop); make.bottom.equalTo(self.view.mas_safeAreaLayoutGuideBottom);

//ok make.left.equalTo(self.view.mas_safeAreaLayoutGuideLeft); make.right.equalTo(self.view.mas_safeAreaLayoutGuideRight); make.top.equalTo(self.view.mas_safeAreaLayoutGuideTop); make.bottom.equalTo(self.view.mas_safeAreaLayoutGuideBottom);

Strangely, just mas_safeAreaLayoutGuide is mapped to bottom. Also, leading and trailing are missing

Turns out, I was using an older version. Leading and Trailing are there now, so you should use something like:

make.top.equalTo(self.contentView.mas_safeAreaLayoutGuideTop).with.insets(margins);
make.leading.equalTo(self.contentView.mas_safeAreaLayoutGuideLeading).with.insets(margins);
make.trailing.equalTo(self.contentView.mas_safeAreaLayoutGuideTrailing).with.insets(margins);
make.bottom.equalTo(self.contentView.mas_safeAreaLayoutGuideBottom).with.insets(margins);

The regular mas_safeAreaLayoutGuide doesn't seem to work if you want to use the shorthand edges.equalTo
