In Swift 2, pointers are permitted to be `nil` even if they're not `Optional`. Swift 3 changes this, and so this parameter would either return `GDALDatasetH?` or, if it hadn't been audited yet, `GDALDatasetH!`. -- Brent Royal-Gordon Architechies _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
