💡 Hint

Common Mistakes

Including the file extension in the resource name.

Using lowercase or incorrect profile names.

The path(forResource:ofType:) method expects the resource name without extension as the first argument and the extension as the second argument.

4fill in blank

Fill both blanks to create a dictionary that maps certificate types to their descriptions.

iOS Swift

let certificateDescriptions = ["Development": "[1]", "Distribution": "[2]"]

Drag options to blanks, or click blank then click option'

AUsed for testing on devices

BUsed for submitting to App Store

💡 Hint

Common Mistakes

Mixing up the descriptions of Development and Distribution.

Using descriptions for Enterprise or AdHoc instead.

The Development certificate is for testing on devices, and the Distribution certificate is for submitting apps to the App Store.

5fill in blank

Fill all three blanks to create a Swift dictionary comprehension that filters provisioning profiles by type and returns their names.

iOS Swift

let profiles = ["DevProfile": "Development", "StoreProfile": "AppStore", "AdHocProfile": "AdHoc"]
let filteredProfiles = profiles.filter { $0.value == "[1]" }.map { $0.[2] }
let result = filteredProfiles.sorted(by: { $0.[3]($1) == .orderedAscending })

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Filtering by Development instead of AppStore.

Using value instead of key to map profile names.

Sorting with < instead of localizedCaseInsensitiveCompare.

This code filters profiles for the AppStore type, maps to their keys (names), and sorts them alphabetically ignoring case.
