Question 1

How do I install FlexLayout using CocoaPods?

Accepted Answer

Add 'pod 'FlexLayout'' to your Podfile and run 'pod install'. FlexLayout also supports Carthage and Swift Package Manager, with detailed setup instructions in the README.

Question 2

Is FlexLayout faster than UIStackView?

Accepted Answer

Yes, the README includes benchmarks showing FlexLayout is 8x to 12x faster than UIStackView on various iPhones, due to its optimized Yoga engine from React Native.

Question 3

Can I use FlexLayout with SwiftUI?

Accepted Answer

No, FlexLayout is built for UIKit and lacks direct SwiftUI support. You would need to wrap it in a UIViewRepresentable for use in SwiftUI projects, adding complexity.

Question 4

How do I handle dynamic content like changing label text in FlexLayout?

Accepted Answer

Call 'markDirty()' on the affected view to flag it for re-layout, then trigger a layout update with 'layout()' or 'setNeedsLayout()', as documented in the README.

Question 5

FlexLayout vs PinLayout: when should I use each?

Accepted Answer

Use FlexLayout for complex, nested layouts with rows and columns; use PinLayout for fine control, absolute positioning, or animations. They can be mixed in the same view for flexibility.

Question 6

Does FlexLayout support percentage-based sizing?

Accepted Answer

Yes, FlexLayout supports percentage values for dimensions, margins, and paddings using the '%' operator, e.g., 'width(50%)', as shown in the examples.

Question 7

What are the main differences between FlexLayout and CSS flexbox?

Accepted Answer

FlexLayout has slight default differences, like 'direction' defaulting to column, and lacks the 'order' property. It also adds iOS-specific methods such as 'markDirty()' for dynamic updates.
