Using PatternImages in SwiftUI that continue out of ScrollView

Hi All,

Currently we migrate out App from UIKits CollectionView to SwiftUI with a Grid. Currently we have encountered two problems:
a) How can we add a Background-Pattern as the Background? Before it was possible with UIColor.colorWithPatternImage and assigning this to the background property of e.g. a UICollectionView. With the SwiftUI color this seems impossible. Do you know how to do this?
b) How can a Background-Color of a ScrollView being set, also as an Pattern-Image, so if we do overscrolling of the ScrollView the pattern should continue. The UICollectionView did this with the background property as well.

Does someone know how to fix this? Thanks a lot in advance!
