如图，需要对字符串中部分字符改变颜色和字体。

在 SwiftUI 中合并带有不同样式的文本，应该使用不同的 Text 实例并将它们合并起来。将实例使用 + 运算符合并起来，每个 Text 实例都保持其自己的样式设置。这种方式可以正常编译并运行，同时支持文本换行。

示例如下：

import SwiftUIstruct ContentView: View {var body: some View {VStack {let priceText: String = "Free trial for 3 days, then $4.99 per week"let restOfTheText = "Humans are part of nature and we follow the laws of the universe to find the meaning of life "let subscriptionInfo = ". Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Subscriptions can be managed and auto-renewal can be turned off in Account Settings in iTunes after the purchase."Text(restOfTheText).font(.system(size: 13)).foregroundColor(Color.gray)+Text(priceText).font(.system(size: 15)).fontWeight(.bold).foregroundColor(Color.white)+Text(subscriptionInfo).font(.system(size: 13)).foregroundColor(Color.gray)}.frame(maxWidth: .infinity, alignment: .center).multilineTextAlignment(.center).padding(.horizontal, 25)}
}struct ContentView_Previews: PreviewProvider {static var previews: some View {ContentView()}
}
