The text doesn't get wrapped in swift UI

After spending a lot of time with an error like this, I can't be 100% certain that this is a lineLimit issue. As of writing this post, the solution I found with more complex views is the following snippet of code to prevent wrapping:

.fixedSize(horizontal: false, vertical: true)

This should prevent the interpreter from collapsing text vertically.

I hope this helps someone.

Try changing the second Text's lineLimit to a number instead of nil:

VStack(alignment: .leading) {
  Text("SwiftUI is a modern way to declare user interfaces for any Apple platform. ")
    .font(.title)
    .color(.red)
    .lineLimit(nil)
  Text("Create beautiful, dynamic apps faster than ever before.")
    .font(.system(size: 20))
    .lineLimit(2)
 }.padding(EdgeInsets(top: 0, leading: 10, bottom: 0, trailing: 10))

Result:

The full solution as of Xcode 11.3 / Swift 5.1 is found across multiple answers here.

The explanation for why this is happening is found in Matteo Pacini's answer: using the predefined .font(.title), .font(.headline), etc. seems to bring the behavior that these Text views will size themselves to always ellipsize rather than wrap. However, simply switching to .body doesn't seem like the best work around.

The best workaround is found in Sharpienero's answer: add .fixedSize(horizontal: false, vertical: true) to your Text view. This tells the Text view to NOT do its custom re-sizing horizontal logic of NOT ellipsizing which causes it to follow the standard rules that we're all use to.

Thanks to both of them!
