以下是SwiftUI中Text一些简单API使用Demo：

        .fontWeight(.bold)
    //fontWeight可选 black bold heavy light medium等等

设置字体大小

   Text("Stay Hungry.Stay Foolish.")
        .fontWeight(.bold)
        .font(.title)
    //font可选 largeTitle title headline subheadline body callout footnote caption等等

使用.system设置字体

   Text("Stay Hungry.Stay Foolish.")
        .font(.system(size: 25, design: .rounded))
        //design可选 serif rounded monospaced

字体颜色

   Text("Stay Hungry.Stay Foolish.")
        .foregroundColor(.red)

使用.custom自定义字体

   Text("Stay Hungry.Stay Foolish.")
        .font(.custom("Helvetica Neue", size: 24))
        .foregroundColor(.red)

处理多行

   Text("Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.Stay Hungry.Stay Foolish.")
        .font(.title)
        .multilineTextAlignment(.center)//居中对齐
        .lineLimit(5)//限制显示5行，多余字符以...代替
        .truncationMode(.head)//多余字符以...代替出现的位置放置在头部而不是尾部

显示所有字符

.lineLimit(nil)

行间距

.lineSpacing(10)
