Instance Property


The selection type of the asset in a burst photo sequence.


var burstSelectionTypes: PHAssetBurstSelectionType { get }


When the user takes a sequence of photos in burst mode with the Camera app (on supported devices), the Photos app user interface groups the resulting assets together and allows the user to select favorite members of the sequence. Photos also automatically marks members of the sequence as potential user favorites. See PHAssetBurstSelectionType for possible values.

Because an asset may have more than one selection type, you use bit masks to identify an asset. For example, the code below tests an asset’s selection type:

if (asset.burstSelectionTypes & (PHAssetBurstSelectionTypeAutoPick | PHAssetBurstSelectionTypeUserPick)) {
    // display two badges in UI
} else if (asset.burstSelectionTypes & PHAssetBurstSelectionTypeAutoPick)) {
    // display auto-selected badge in UI
} else if (asset.burstSelectionTypes & PHAssetBurstSelectionTypeUserPick)) {
    // display user-selected badge in UI
