Known limitations and recommendations
Section titled Known limitations and recommendationsSnapshot fidelity: Combining Visual Effects with Filters
Section titled Snapshot fidelity: Combining Visual Effects with FiltersSymptom: Some elements of the snapshots may not be visible (e.g UITabBar buttons).
Explanation: Our capturing method prevents to capture views when Visual effects are combined with filters. Our tools captures as much as Xcode’s ‘Debug View Hierarchy’ feature. If you want to preview what is going to be rendered, you can use this feature to visualize your screen. Capturing a Snapshot of a UIVisualEffectView.
Gestures not attached to UIImageView
Section titled Gestures not attached to UIImageViewSymptom: When analysing the tap rate on an image, we see 0% when we know it is not possible.
Explanation: By default UIImageView
have their isUserInteractionEnabled
property set to false (See Apple documentation).
This means that the UIImageView
won’t receive any input event. All events will be handled by the first parent to have isUserInteractionEnabled
set to true (usually the first parent will do).
Workaround: Create a zone on the parent view to get the taps on the image.
UICollectionViewCompositionalLayout
TVP lack of consistency
Section titled UICollectionViewCompositionalLayout TVP lack of consistencyExplanation: As explained in the Apple documentation, UICollectionViewCompositionalLayout
is a highly dynamic layout creation object. We are not able to ensure TVP value is the same between different usages.
Zoning Limitation in SwiftUI with VStack / LazyVStack
Section titled Zoning Limitation in SwiftUI with VStack / LazyVStackThe current snapshot and gesture tracking capabilities are limited in some cases when SwiftUI with VStack/LazyStack are used.
