What is the output of this Swift code related to App Store presence?
Consider this Swift code snippet that simulates app download count update:
let downloads = ["AppA": 1200, "AppB": 800]
let newDownloads = downloads["AppA"] ?? 0 + 300
print(newDownloads)
What will be printed?
iOS Swift
let downloads = ["AppA": 1200, "AppB": 800] let newDownloads = downloads["AppA"] ?? 0 + 300 print(newDownloads)

💡 Hint
Remember operator precedence and how the nil-coalescing operator works.
✗ Incorrect
The expression `downloads["AppA"] ?? 0 + 300` is parsed as `(downloads["AppA"] ?? 0) + 300` because + has higher precedence than ??. `downloads["AppA"]` returns 1200 (non-nil), so ?? returns 1200, then 300 is added, resulting in 1500.
