The app crashes when creating a new album. This crash did not occur in our own testing, but after publishing it to the app store, it seems that the probability of occurrence is very high.
How are we supposed to help you with this? What's an album? What code are you running that's causing the crash?
PHFetchResult<PHAssetCollection *> *collectionResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:@[placeholder.localIdentifier] options:nil];
crash in this line
__block PHObjectPlaceholder *placeholder = nil;
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetCollectionChangeRequest *request = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:title];
placeholder = request.placeholderForCreatedAssetCollection;
} completionHandler:^(BOOL success, NSError *error) {
if (resultBlock) {
PhotoAlbum *resultAlbum = nil;
if (placeholder) {
PHFetchResult<PHAssetCollection *> *collectionResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:@[
placeholder.localIdentifier
