Describe the bug

TextView's size didn't update

Steps to reproduce

Provide numbered steps to follow that reproduce the bug.

2. Delete Presentation and Browsers packages since they can't run on Xcode 12.5.1
3. Delete PresentationDemo and ScrollViewDemo since the package has been deleted

Expected behavior

The text2 string should be fully displayed

Stack trace, compiler error, code snippets

Nope

Screenshots

Only display the first line of string

Additional context

Changing TextView.swift's calculatedHeight default value to 0 fix the problem.

I'm confused as to what issue you're having here. From the screenshots all looks ok?

The screenshot of Expected behavior is captured after I modify TextView.swift's calculatedHeight to 0

@retsohuang I'm thinking you're misunderstanding how its supposed to work, maybe?

So the 1st screenshot is correct. The view is automatically sizing itself to fit the text, growing and shrinking as required.

The 2nd screenshot it what you'd expect from a TextField (which SwiftUI already provides) where only a single line of text is possible, no wrapping.

Setting the calculatedHeight = 0 will actually break autosizing completely, so that's definitely not a 'solution' to any problem.

Let me know if that clarifies things, but I think you're looking for a lineLimit feature on this view, which is not currently supported as TextField already performs that task perfectly.
