叠加过渡问题

Question

我有一个叠加层，它会在切换为真时显示。当它显示时，它应该有一个从视图的右到左的过渡，以便在视图之间实现良好的过渡。问题是动画从右上角以对角线运动向下移动。

我假设动画不正确或者叠加层的动画有问题。

预先感谢您的帮助。

试试这个

.overlay(
   VStack {
      if showFitnessForm {
        FitnessForm(...)
          .transition(transition)   // << here !!
      }
   }
   .animation(Animation.easeInOut(duration: 1.0), value: showFitnessForm)  // << here !!
)
