Question 1

How to handle dynamic content changes with FlexLayout?

Accepted Answer

Use the markDirty() method on flex items when content changes, then call layout() on the container. This forces a re-layout, as explained in the README's markDirty() section.

Question 2

Can FlexLayout be used with Auto Layout constraints?

Accepted Answer

No, FlexLayout is designed as a replacement for Auto Layout and should not be mixed with constraints. It operates independently within a view hierarchy for layout calculations.

Question 3

FlexLayout vs UIStackView: which is better for performance?

Accepted Answer

FlexLayout is significantly faster, with benchmarks showing 8–12x speed improvements over UIStackView, making it ideal for complex or scroll-heavy interfaces where performance matters.

Question 4

How to debug layout issues in FlexLayout?

Accepted Answer

Use methods like sizeThatFits() to inspect calculated sizes, ensure containers are laid out in layoutSubviews(), and check for common issues like incorrect shrink values, as noted in the README's FAQ.

Question 5

Does FlexLayout work with SwiftUI?

Accepted Answer

No, FlexLayout is built for UIKit-based iOS apps. For SwiftUI, use SwiftUI's native layout system or explore other third-party options tailored for SwiftUI.

Question 6

How to integrate FlexLayout with UITableView cells?

Accepted Answer

Define flex containers within cell subviews and layout them in the cell's layoutSubviews() method. The README provides example apps demonstrating this with table and collection views.

Question 7

FlexLayout or PinLayout: when should I use each?

Accepted Answer

Use FlexLayout for complex, multi-item flexbox layouts; use PinLayout for absolute positioning, fine control, or animations. They can be combined, as highlighted in the README's integration section.
